National Summary

Background

This annual report on New Zealand’s drinking-water quality spans the period July 2008 to June 2009 and covers the second year of reporting by financial year rather than calendar year. This is also the third year for which the Drinking-Water Standards for New Zealand: 2005 (DWS 2005) could be used to assess the microbiological and chemical quality of drinking-water. However, as the transition from the Drinking-Water Standards for New Zealand: 2000 (DWS 2000) to the DWS 2005 is scheduled to take several years and drinking-water suppliers may elect which of these they are to operate under, compliance is assessed against the standard which the supplier has chosen to comply with. These standards are referred to collectively as DWSNZ. The report comprises the following sections: a general overview of the quality of drinking-water of all supplies within New Zealand; a summary of the nation’s drinking-water quality, with supplies separated into local authority (LA)-operated supplies, school- and early childhood centre (ECC)- operated supplies; an overview of drinking-water quality in each district health board (DHB) area; a summary of the quality of drinking-water in each LA area; Appendix 1 (microbiological and chemical compliance with the DWSNZ of individual water supplies); Appendix 2 (supplies that ceased to be monitored in 2008/9); Appendix 3 (supplies with inadequate corrective action); Appendix 4 (LA-run supplies serving 500 or more people that were technically non-compliant); Appendix 5 (supplies in which bacteriological compliance ceased); Appendix 6 (waterborne outbreaks summary); Appendix 7 (Public Health Service Providers); Appendix 8 (compliant zones with excessive Escherichia coli transgressions at the treatment plant); and, Appendix 9 (supplies in which anomalies occurred between monitoring and surveillance results). The information on the quality of drinking-water was obtained from the Drinking Water Assessors (DWAs) using questionnaires that sought data concerning surveillance and monitoring programmes carried out by DWAs and water suppliers, respectively. Water suppliers fall into two groups: LAs, including commercial water supply companies contracted by LAs, and private organisations or communities responsible for the operation of their own drinking-water supplies, of which schools have been considered separately. Water suppliers are responsible for water quality monitoring, whereas the DWAs carry out surveillance of the management of drinking- water quality in their health districts. The survey sought information about both distribution zones and water treatment plants. In addition to microbiological and chemical quality information, the questionnaire collected information about the water treatment processes in use and the means used to demonstrate compliance with the DWSNZ. Information was also gathered about the status of the Public Health Risk Management Plan (PHRMP) for each supply. To evaluate the public health significance of the water quality data they are expressed primarily in terms of the population affected rather than the numbers of water supplies involved because different-sized populations are served by different water supplies.

Annual Review of Drinking-Water Quality in New Zealand 2008/9 1

While the distribution zone figures refer to the percentage of the total population of New Zealand, double-counting caused by many treatment plants supplying multiple zones, has meant that in the past the plant population percentages were estimates of the percentage of the population served by registered supplies. For the 2008/09 Annual Survey an alternative approach to population counting has been used because most of the population figures relate to treatment plants. Where a zone is supplied by more than one treatment plant, and the treatment plants are not equally compliant, the zone assumes the compliance status of the lowest-complying treatment plant. For example, protozoal compliance is reported for the zone and will be the same as the the treatment plant that has the lowest compliance (eg. where two plants supply a zone with one plant protozoal-compliant and one not, the zone and its corresponding population is regarded as non-compliant). The 2009 Register of Community Drinking-water Supplies in New Zealand (the Register) contained 2,339 distribution zones and 2,296 water treatment plants and covered an estimated 89% of the New Zealand population. The microbiological and chemical quality of drinking-water was assessed against the DWSNZ using a survey of all treatment plants and distribution zones. The version of the DWSNZ being used by water suppliers as a measure of compliance was fairly evenly split between the DWS 2000 and DWS 2005, these being applied in 785 and 819 distribution zones, respectively, with the remainder not applying the DWSNZ. Information was received from DWAs about all supplies reported on, but 77 water suppliers could not be contacted and a further four were either unable or unwilling to provide monitoring data. The microbiological health risk was assessed using compliance criteria based on two main microbiological reference organisms, Escherichia coli and Cryptosporidium. Bacteriological compliance is determined primarily using E. coli monitoring, whereas protozoal compliance is based on monitoring the effectiveness of the treatment processes used to remove or disinfect Cryptosporidium. The chemical health risk for selected supplies was assessed with respect to those specifically-assigned chemical determinands which required monitoring.

Key findings

The overall level of drinking-water quality in 2008/9 was as follows: E. coli compliance

Percentage of New Zealand population served by registered reticulated drinking-water 80% supplies known to comply with the distribution zone E. coli requirements of the DWSNZ. [These are generally located in towns with populations in excess of 5,000 people.] Percentage of New Zealand population served by reticulated drinking-water supplies 9% not compliant with the distribution zone E. coli requirements of the DWSNZ. [These are generally located in towns with populations of less than 5,000 people.] Percentage of New Zealand population not served by registered reticulated drinking- 11% water supplies. [In most instances these people are in buildings that are self supplied with drinking-water eg. from a roof tank or bore.]

Protozoal compliance (new and old method of population estimation)

Percentage of New Zealand population served by registered reticulated 63% drinking-water supplies known to comply with the protozoan requirements of the DWSNZ. [These are generally located in towns with populations in excess of (76%)* 5,000 people.] Percentage of New Zealand population served by reticulated drinking-water 26% supplies not compliant with the protozoan requirements of the DWSNZ. [These are generally located in towns with populations less than 5,000 people.] (13%)* Percentage of New Zealand population not served by registered reticulated 11% drinking-water supplies. [In most instances these people are in buildings that are self supplied with drinking-water eg. from a roof tank or bore.] * the figures in brackets represent the proportion of the populations as estimated using the previous method (see comment on p2) and are included for comparison. During 2008/9, water supplies to 80% of New Zealanders were served by community drinking-water supplies that complied with the E. coli criteria of the DWSNZ. This represents a decrease of 3% from the previous survey and a return to 2006/7 compliance status. Most large communities were served by water supplies which demonstrated microbiological compliance with the DWSNZ during 2008/9. However, many smaller communities were supplied with microbiologically non-compliant drinking-water. The general trend in bacteriological compliance is best assessed at the distribution zone and is shown in Figure 1 which shows the changes since the Ministry of Health drinking-water quality surveys commenced in 1994. The complete details of distribution zone compliance for each health district are given in Appendix 1.

Figure 1: Trend in bacteriological compliance at the distribution zone The general trend in protozoal compliance is assessed at treatment plants and is shown in Figure 2. The estimated proportion of the population supplied by protozoal- compliant plants (76%) has not changed since the previous survey. However, to estimate the population that may be exposed to protozoal contamination it is necessary to include only supplies that were entirely protozoal-compliant (ie. zones supplied by multiple plants of mixed protozoal compliance are non-compliant). When

viewed this way, 63% of the population were served only by plants that had protozoal compliance during 2008/9. The dip in compliance shown on Figure 2 is an artefact resulting from the changed method of reporting and should not be interpreted as a decline in overall protozoal compliance.

Figure 2: Trend in protozoal compliance at the treatment plant There was a general trend for the percentage of distribution zones complying bacteriologically within a population band to decrease as the population of the band decreased (ie. the smaller the community water supply, the less likely it is to comply with the DWSNZ). Approximately 849,000 (20%)1 of New Zealanders were supplied with drinking-water that either failed to comply bacteriologically with the criteria of the DWSNZ or for which there are no data because they were unregistered. The causes of non- compliance and the number of people affected are listed below:

• 93,000 (2%) were served by registered supplies with unacceptable levels of E. coli.

• 34,000 (1%) were served by registered supplies where water suppliers failed to take appropriate corrective action once E. coli had been found.

• 87,000 (2%) were served by registered supplies where E. coli monitoring was either not carried out or where monitoring data were not available.

• 247,000 (6%) were served by registered supplies that did not comply bacteriologically with the DWSNZ because the frequency of sampling during the year was insufficient to demonstrate E. coli compliance according to the DWSNZ.

• 1,500 (0.04%) were served by registered supplies that did not comply bacteriologically because the compliance testing was not analysed by a

laboratory registered by the Ministry of Health for drinking-water compliance testing.

• 456,000 (11%) were household supplies (eg. bore or tank etc.).

The number of people in zones with unacceptable levels of E. coli, inadequate corrective actions following bacteriological transgressions, or that were monitored by laboratories not recognised by the MoH, fell since 2007/8. However, in 2008/9 there was an increase in the number of people in supplies that were not monitored or inadequately monitored. There is a perception that water that is shown to contain E. coli is a greater risk to public health than water that is not tested. The reality is that, apart from groundwater from a confined aquifer, all source waters are faecally-contaminated and so will contain the faecal indicator bacterium E. coli unless the water is adequately treated. To discourage the practice by some water suppliers of attempting to avoid scrutiny by ceasing monitoring, details of the 125 supplies that ceased monitoring in 2008/9 are given in Appendix 2. One of the reasons for monitoring is to identify hazards and remedy them rapidly if they occur. The number of people served by supplies in which E. coli transgressions occurred and that were not appropriately followed up by immediate corrective action decreased markedly between 2007/8 and 2008/9. Although a decrease occurred, this issue remains a concern because failure to remedy the cause of a transgression subjects the population to prolonged exposure to faecally-contaminated drinking- water and imposes an unacceptable risk of waterborne disease on the community. Details of the LA-run supplies that failed to take appropriate corrective action in 2008/9 are given in Appendix 3. Of these 33 LA-run supplies, 15 were reported for the same practice in the previous review (2007/8). Otorohanga, Marlborough, Hurunui, Selwyn and Waitaki District Councils should urgently review and improve their corrective action procedures following bacteriological transgressions. It is acknowledged that some of these supplies are subject to permanent boil-water notices, however this is not considered to be appropriate long term solution. A further 512,000 people were supplied with drinking-water from 96 zones that failed to comply bacteriologically with the criteria of the DWSNZ for technical reasons. These fell into two groups. Supplies serving less than 500 people that failed only to comply with the minimum number of days-of-the-week sampling requirement of the DWS 2000 were deemed to comply because there is no such requirement in the DWS 2005. Supplies serving communities of 500 or more people that were adjudged by the DWA to have addressed the deficiency were deemed to have complied with the DWSNZ. Details of the latter group are given in Appendix 4. There were 160 supplies, serving a total of approximately 55,000 people that complied bacteriologically in 2007/8 but not in 2008/9. Details of these supplies are given in Appendix 5. During 2008–09, approximately 3,699,100 people were supplied by water that met the chemical compliance requirements of the DWSNZ. This represents 86% of the population in registered water supplies, and is an improvement on the 82% chemical compliance in 2007–08. Included in this count are those people receiving water from

distribution zones to which Priority 2 (P2) determinands2 have not been assigned (chemically compliant by default), and those drawing from distribution zones to which P2 determinands have been assigned and that have demonstrated compliance through monitoring. The trends in the causes of bacteriological non-compliance of distribution zones are displayed in Figure 3. Overall, there is a steady downward trend in the number of zones that are not monitored or are inadequately monitored and those that use non- recognised laboratories for compliance monitoring. The former reflects the slow but sustained updating of monitoring programmes to comply with the procedures specified in the DWSNZ.

Figure 3: Trend in the causes of distribution zone non-compliance

The large increase in the number of inadequately monitored supplies between 2000 and 2001 was caused by the increased stringency in monitoring requirements prescribed in the DWS 2000 compared to the requirements of the DWS 1995, particularly regarding the minimum days-of-the-week and maximum interval between successive samples criteria. While this aspect of compliance has steadily improved since 2001, many water suppliers have still not yet updated their monitoring programmes.

Chemical substances or determinands that are present in a water supply at potentially health-significant concentrations (usually 2 greater than 50% of their MAV) are the only chemical determinands that must be monitored to comply with the chemical criteria of the DWSNZ:2005. These chemical determinands are known as Priority 2 (P2) determinands and are of two types: determinands introduced in treatment chemicals, including intentionally-added fluoride, (P2a); and determinands from any other source (P2b). At present, P2 classifications are only notified in the Register for distribution zones with populations of 500 or more people. Water supplies that have not been assigned a P2 determinand are classed as compliant with the chemical requirements of the DWSNZ:2005. Where a supply has no P2 assignation because the supply has not been assessed with respect to its chemical contaminants the safety of the supply with respect to chemical determinands is uncertain. The relative softness of New Zealand’s water sources results in a general tendency for our drinking waters to dissolve metals from plumbing fittings: a property termed plumbosolvency in the DWSNZ:2005. All drinking waters are designated as plumbosolvent unless the water supplier can show they are not. Metals arising from plumbosolvency do not have to be monitored, provided the public is advised to flush their taps before drawing water for consumption.

Annual Review of Drinking-Water Quality in New Zealand 2008/9 6

This survey cannot distinguish between the two main reasons for inadequate monitoring: poor understanding of the DWSNZ monitoring requirements, or a reluctance to address the monitoring deficiencies. The failure to take appropriate corrective action immediately following E. coli transgressions is a serious cause of concern because of the public health consequences that could follow if the failure coincided with elevated pathogen concentrations in the source water. Failure to reduce this risk by increased disinfection or by taking appropriate steps to reduce the hazard (ie. closing or changing the supply) or exposure (ie. recommending that people do not drink unboiled water) increases the likelihood of waterborne disease. Inadequate corrective action is indicative either of the failure of the water supplier to recognise this issue or to accept that it poses a potentially serious health risk. Numerous waterborne disease outbreaks have occurred in New Zealand in recent years. During 2008/9, 33 waterborne outbreaks involving 115 cases were recorded3 (see Appendix 6), of which untreated or contaminated supplies were identified as a contributing factor in most of them. It is unlikely that this situation will change appreciably while so many drinking-water supplies, particularly those serving small communities, do not employ adequate risk management practices including treatment. Two hundred and twenty three distribution zones had at least one P2 determinand assigned to them, or received water from a treatment plant with at least one P2 determinand. These zones supplied water to 2,606,700 people. Zones with P2 assignations that demonstrated chemical compliance provided water to approximately 2,446,200 people. Distribution zones in which a maximum acceptable value (MAV) was exceeded supplied water to 73,560 people. Unsatisfactory monitoring remains a major reason for non-compliance with the chemical criteria of the DWSNZ. Monitoring for fluoride as a Priority 2a (P2a) determinand was required at 51 treatment plants where fluoride was intentionally added ─ these treatment plants supplied a combined population of approximately 2,243,800 people. Water from treatment plants meeting the fluoride MAV specified in the DWSNZ was provided to almost 100% of this population.

Detailed summary of survey data To evaluate the public health significance of the water quality data contained in this report, summary statistics are expressed in terms of the population affected. Since expression of the zone numbers may be of more value for regulation and water supply management, data are summarised in both ways. Information was received for each of the 2,339 distribution zones and 2,296 water treatment plants listed in the Register as at June 2009 covering approximately 3,860,000 people. The remaining 456,000 people were not connected to a registered supply. During 2008/9, the number of registered zones increased by 37, and the number of people served by registered supplies rose by 14,000 due to revised distribution zone population estimates exceeding the population in zones deregistered

3 NB as most GID cases are sporadic and not related to outbreaks, and the proportion of cases that are notified is very small, this figure will greatly under-estimate the prevalence of w/b disease.

or closed by June 30. During the same period the number of people on household supplies increased by 137,000 or 3%, of which 1,000 people were from zone closures. The likely explanation of this increase is that the zone populations have generally not been updated in line with the census estimates.

Distribution zone bacteriological monitoring and compliance Less bacteriological monitoring was carried out in smaller supplies than in larger supplies, both in terms of the percentage of zones monitored and the percentage of zones adequately monitored. During 2008/9, 98% of the population served by registered supplies lived in distribution zones where some monitoring was conducted. This situation has not changed since 2007/8.

Water supplied to 82% of the New Zealand population, or 37% of distribution zones, was adequately monitored as per the requirements of the DWSNZ. This represents a decline of 3% in population terms since 2007/8. During 2008/9, 80% of the population lived in distribution zones supplied with drinking-water that complied with the distribution zone E. coli criterion, a 3% decrease since 2007/8 (Table 1). By the end of the 2008/9 period there were 264 graded supplies listed in the Register.

Annual Review of Drinking-Water Quality in New Zealand 2008/9 8

Treatment plant microbiological compliance An estimated 71% of the population, supplied by 7% of treatment plants4 was supplied with drinking-water that fully complied with the microbiological criteria of the DWSNZ during 2008/9. Bacteriological compliance increased slightly in 2008/9 with 53% of treatment plants demonstrating E. coli compliance. In terms of the population served, 87% of the population served by bacteriologically-compliant treatment plants, an improvement of 4% since the previous year. Cryptosporidium compliance was demonstrated in 8% of treatment plants supplying 63%5 of the population on registered water supplies (Table 1). Treatment plants serving small supplies tended to be less adequately monitored and a smaller proportion complied with the DWSNZ. A number of zones were reported as being E. coli-compliant when the treatment plants were bacteriologically non-compliant due to excessive E. coli transgressions (Appendix 8). While it is possible for this to be accurate, it indicates a possible problem with the sampling and/or accuracy of the data and warrants further investigation.

Cyanobacterial blooms Cyanobacterial blooms that are potentially toxigenic can occur in surface waters and anecdotally appear to be increasing in occurrence. The presence of cyano-blooms is noted as part of treatment plant grading. As of December 2009, cyano-blooms have been noted in 35 of the 354 graded treatment plants and 28/96 (29%) surface source waters. This aspect will be examined in more detail in future reports.

Surveillance Surveillance is carried out by DWAs either by auditing or surveillance testing of selected water supplies. During 2008/9, E. coli was detected by surveillance testing in six supplies (Appendix 9) that were reported by the water supplier as bacteriologically compliant with the DWSNZ. This is indicative of a likely problem with some aspect of zone monitoring and should be investigated by the water supplier. This situation is a little worse than in 2007/8, when three zones showed discrepancies of this nature.

Validity of compliance monitoring All compliance testing for LA-run supplies is now being carried out by Ministry of Health-recognised laboratories. However, 23 non-LA supplies are still using other laboratories to analyse compliance samples. Laboratories seeking to be included on this register should apply to: International Accreditation New Zealand Private Bag 28908 Remuera, Auckland 1136 Ph: (09) 525 6655 Fax: (09) 525 2266 Email: [email protected]

4 A treatment plant is defined as the point where water enters the distribution system, irrespective of whether the water is treated or not. 5 The apparent decrease from the 76% compliance in the previous report is an artefact caused by the change from estimated to actual populations reported for treatment plant compliance (see p2 of this report).

Use of non-recognised laboratories will result in the water supply not being in compliance with the DWSNZ. If the water supplier cannot access a recognised laboratory, the DWA should be consulted about possible options.

School and early childhood centre drinking-water supplies Compliance with the DWSNZ at school- and ECC- supplies was about the same as in 2007/8. The 597 school/ECC supplies comprised one-fifth of all registered drinking- water supplies in 2008/9. During 2008/9, 421 (71%) of the schools/ECCs with their own water supplies conducted some bacteriological monitoring, seven more than in 2007/8. Of these, 118 supplies (20%) complied with the bacteriological criteria of the DWSNZ, 3% more than in 2007/8 Many of the schools have installed ultraviolet (UV) treatment in conjunction with cartridge filtration in recent years. Most UV treatment devices used provide adequate treatment to kill bacteria and therefore reduce the likelihood of bacteriological transgressions. However, a greater dose of UV is required to kill some viruses and protozoan parasites. The first four school supplies achieved protozoal compliance in 2008/9. It is possible that some of the UV devices installed will not be adequate to comply with the drinking-water standards for protozoa.

Private drinking-water supplies There were 1,049 distribution zones designated as private supplies during 2008/9, supplying water to approximately 143,000 people. Of these, 11%, serving 30% of people connected to private supplies complied bacteriologically with the DWSNZ. This represents a decline during the past 12 months.

Hospital and health services drinking-water supplies At the end of the 2008/9 period, 12 hospitals and health services were not connected to municipal drinking-water supplies. Five of these were bacteriologically non- compliant with the DWSNZ. Waiheke Health Trust and Princess Margaret Hospital failed to follow appropriate corrective action procedures following a bacteriological transgression. Excessive bacteriological transgressions were reported in two supplies (Waiheke Health Trust and Te Puia Springs Hospital and Village). Two supplies were not monitored (Aotea Health and Great Barrier Community Health).

Corrective actions The DWSNZ prescribes that any transgression is immediately followed by a corrective action and is documented. Corrective actions following transgressions in 39 zones were inadequate and/or tardy and were probably not carried out in a further 62 zones. This aspect has improved greatly since 2007/8. Note: Section 69ZF of the Health (Drinking Water Amendment) Act 2007 requires the drinking-water supplier to take remedial (corrective) action if drinking-water standards are breached.

Disinfection Several methods of drinking-water disinfection have been reported in New Zealand, comprising chlorination, ozonation and UV irradiation. Chlorination remains the most popular means of drinking-water disinfection and served 77% of people connected to registered drinking-water supplies or 25% of treatment plants. Secure groundwater supplies are used by 16% of people connected to registered drinking-water supplies; these comply with the DWSNZ without the need for disinfection. Bacteriological compliance was demonstrated in supplies to 93% of the population on chlorinated supplies or 59% of treatment plants using chlorination, which is about the same as for the previous year. Most of the non-compliance in chlorinated supplies was caused by lack of monitoring, although 69 were contaminated with E. coli during 2008/9, 21 more than in 2007/8. The number of treatment plants using UV treatment increased by 44 during 2008/9. This is particularly popular for treating small community supplies, particularly schools, probably because of the low costs associated with its installation and operation. Of the 763 UV-treated supplies, 60% complied bacteriologically with the DWSNZ. This represents an improvement in bacteriological compliance of UV- treated supplies compared with 2007/8. Non-compliance mostly resulted from inadequate or no monitoring, although E. coli were detected in 23 of these supplies during 2008/9, six more than in 2007/8. Of the plants using UV treatment, 71 were reported to use UV without filtration. While this can be acceptable treatment it is unusual for UV disinfection to be effective unless the water is filtered. Consequently, it is likely that many of these plants will have been either misreported or require filtration. Thirteen of the 23 treatment plants using ozone treatment complied microbiologically with the DWSNZ during 2008/9, with lack of monitoring being the cause of non- compliance in all except one case, the other being inadequate monitoring. The percentage of plants using ozone that complied microbiologically6 with the DWSNZ increased from 30% in 2007/8 to 57% in 2008/9.

P2 chemical determinand monitoring The assignation of a P2 chemical determinand to a distribution zone or treatment plant indicates that monitoring of the water has shown that determinand to be present in the water at potentially health significant concentrations (greater than 50% of its MAV). The assignation requires the water supplier to undertake regular monitoring until it can be shown that the determinand’s concentration has been reduced so that it is consistently less than 50% of its MAV. Not all water suppliers are required to undertake monitoring for the same determinands, only those found to have been a concern in their supply. During 2008–09, 223 distribution zones had at least one P2 determinand assigned to them, or received water from a treatment plant with at least one P2 determinand. These zones supplied water to 2,606,700 people. A total of 16 different determinands were monitored in these distribution zones and associated treatment plants. Zones

6 The term microbiological compliance includes both bacteriological and protozoal compliance. The term bacteriological compliance is used when it is not appropriate to use microbiological compliance (eg. in relation to chlorine, which are effective treatments for bacteria but not protozoa).

Annual Review of Drinking-Water Quality in New Zealand 2008/9 11

with P2 assignations that demonstrated chemical compliance provided water to approximately 2,446,200 people. There was a total of 272 assignations during 2008-097. Excluding the fluoride assignations, the majority were for heavy metals or disinfection by-products (a total of 196 for these two classes of determinand). Compliance was achieved for 165 (61%) of the assignations, but non-compliance resulted from: no, or inadequate, monitoring (70 assignations), use of a laboratory that was not MoH-recognised (2 assignations), concentrations exceeding an MAV (36 assignations) and inadequate corrective action in the event of an MAV being exceeded (32 assignations). Distribution zones in which an MAV was exceeded supplied water to 73,560 people. As has been observed in previous years, no or inadequate monitoring was the primary reason for non- compliance. Fifty-one treatment plants were required to monitor for fluoride because of the intentional addition of fluoride. These provided water to 2,243,800 people in 123 distribution zones. Two fluoridating treatment plants were non-compliant because the fluoride MAV was exceeded. These supplied water to a total of 11,412 people. One of the transgressions (Huntly) just exceeded the MAV on one occasion whilst the other (Balclutha) was more serious and occurred on two occasions. Water suppliers need to ensure regular checking of dosing equipment is part of normal operating procedure. The DWS 2005 (2008 revision) require supplies with plumbosolvent water serving more than 500 people to advise their consumers to flush their taps before drawing water to drink. The DWS version published in 2005, on the other hand, requires this action in distribution zones supplying water to more than 1,000 people. Making allowance for the possibility that supplies in the 501-1,000 population bracket using the 2005 version of the DWSNZ may not have considered the provision of advice to the public a requirement of compliance, a total of 318 distribution zones were required to provide advice to consumers. Of these, 261 (82%) reported they had advised their consumers to flush their taps. This is a great improvement on the 61% of last year. Advice to consumers to flush sufficient water from the tap to eliminate metals leached from the fittings needs to be provided by all suppliers, unless they have undertaken the necessary testing to show their water is not plumbosolvent. In supplies where metals have been assigned as P2 determinands, the supplier should aim to undertake sufficient monitoring to demonstrate that the metals do not exceed 50% of their MAV in the reticulated water. If this can be shown, the metal can be reassigned as a P3 determinand, and monitoring may cease.

Status of Public Health Risk Management Plans PHRMPs are recommended for reasons of good practice. Following the passing of the Health (Drinking Water) Amendment Act in October 2007, the Health Act includes a provision to require each water supply serving more than 500 people to be covered by a quality assurance programme in the form of a PHRMP. This

7 The number of assignations is greater than the number of zones to which assignations were made because more than one determinand may be assigned to a zone, either directly or through the treatment plant feeding the zone.

requirement was to have been phased-in between 2009 and 2013, depending on the population served by the supply, but this has been delayed for three years. By the end of the 2008/9 period, work had been initiated on 650 PHRMPs, which comprised 28% of supplies. Of these, 407 have been submitted and 341 of those approved or implemented. The amended deadline for water suppliers to submit draft PHRMPs for the different- sized supplies are as follows: • Large supply (serving > 10,000 people): 1 July 2012 • Medium supply (serving 5,001–10,000 people): 1 July 2013 • Minor supply (serving 501–5,000 people): 1 July 2014 • Small supply (serving 101–500 people): 1 July 2015 • Neighbourhood supply (serving 25–100 people): 1 July 2016

Key Issues

A number of important issues are highlighted in this review. These are listed below. • Overall compliance has fallen by 3% in population terms during 2008/9. Approximately 80% of New Zealanders have bacteriologically-compliant drinking-water and protozoal-compliance was achieved in supplies serving 63% of the population. • Of the 68 large supplies (ie. serving 10,000 or more people), four did not achieve bacteriological compliance and 18 did not achieve protozoal compliance in the survey year. • Five of the hospital/health services with their own water supplies were bacteriologically non-compliant during 2008/9. Monitoring programmes need to be established for the supplies serving Aotea Health and Great Barrier Community Health. Waiheke Health Trust and Princess Margaret Hospital need to review/implement their corrective action procedures. The cause of the E. coli transgression in the Te Puia Springs Hospital and Village supply needs to be investigated and remedied. • The improvement in compliance of school supplies has continued, with 20% of schools complying in 2008/9. • Some water suppliers could avoid the need to undertake monitoring for P2 heavy metals by sampling to show the metals arise from the plumbosolvency of the water, and are not present in the water supplied to the consumer. DWAs can advise on the protocol required. • Monitoring for E. coli ceased in a further 125 water supplies during the 2008/9 period (Appendix 2). • During 2008/9, the number of LA-run zones in which bacteriological transgressions were not followed up with adequate corrective action remains high at 32 (Appendix 3). This needs attention. • Bacteriological compliance was lost in 160 zones, including three LA-run zones, between 2007/8 and 2008/9 (Appendix 5). • Zones recorded as compliant but served by one or more treatment plants that did not comply bacteriologically because of excessive E. coli transgressions warrant further investigation (Appendix 8). • Discrepancies between the results of bacteriological monitoring by the water supplier and bacteriological surveillance by the DWA occurred in only six zones during 2008/9 (Appendix 9).

General comment on supplies (as derived from appendices) Attention needs to be given to protozoal treatment throughout this district. LA-run supplies - ☺ Far North and Whangarei District Councils are commended for maintaining a high degree of bacteriological compliance in their supplies. / some LA-run supplies in the Far North and Kaipara districts still have not implemented E. coli monitoring programmes; they need to do so. School/ECC supplies - Monitoring and compliance have improved markedly during 2008/9. Other supplies - a large proportion are still not monitored. The Mangonui Drinking Water supply operated by the Doubtless Bay Water Supply Company is the only drinking water supply in Northland serving more than 500 people that does not routinely monitor for E. coli .

General comment on LA-run supplies (as derived from appendices) Whangarei District Council is congratulated for maintaining bacteriological compliance in all supplies during the past year. Chemical compliance was achieved for all P2 determinands except THMs in the Bream Bay supply, where there were 2 transgressions. Corrective actions were regarded as being inadequate. WDC has installed MIEX treatment at Ruakaka WTP in an attempt to reduce THM concentrations.

General comment on supplies (as derived from appendices) LA-run supplies - ☺ North Shore and Papakura City Councils are commended for their continued perfect compliance record. Many of the smaller supplies in the other districts do not achieve protozoal compliance; the optimal means of achieving protozoal compliance should be determined and implemented. School/ECC supplies - Many of the schools could benefit from some advice about sample scheduling or encouraged to begin monitoring. Other supplies - most are still not monitored.

General comment on LA-run supplies (as derived from appendices) Full compliance of all supplies is being impeded by the Orapiu Wharf supply, which is presently not monitored, and Matiatia Wharf, which was inadequately monitored. A bacteriological monitoring programme should be established for Orapiu Wharf as it is not acceptable for LA-run supplies to be not monitored. The council continues to ensure all fluoridating treatment plants are compliant.

General comment on LA-run supplies (as derived from appendices) ☺ The council is commended for achieving a perfect bacteriological compliance record during the past year. / None of the Franklin zones achieved protozoal compliance; the optimal means of achieving protozoal compliance should be determined for all supplies. Increasing the number of samples for nitrate analysis in the Bombay supply should overcome compliance problems with this supply. The number of transgressions for boron at Clarks Beach show the extent of the problem, and possible solutions need to be investigated.

General comment on supplies (as derived from appendices) Most of the rural supplies do not achieve protozoal compliance; for these supplies the optimal means of achieving protozoal compliance should be determined. LA-run supplies - ☺ Hamilton City and Waipa District Councils are commended for maintaining complete bacteriological compliance during the past year. / The Hauraki, Otorohanga, Ruapehu and Waikato District Councils need to take appropriate corrective action following E. coli transgressions. It is suggested that these councils be reminded again of the public health significance of faecally-contaminated drinking-water. School/ECC supplies - overall bacteriological compliance of school/ECC supplies improved slightly during the past year. The schools with excess E. coli transgressions fell to 15 but 10 of them failed to conduct adequate corrective action. Further education about the public health significance of drinking E. coli -contaminated water may be useful. It also would be useful to find out whether additional treatment or improved procedures are required and, if the former, to advise the Ministry of Education. Most schools /ECCs are not monitored often enough; it would be useful to ascertain and remedy the impediments to full monitoring. Other supplies - there appear to be very few private supplies registered in the Waikato district.

General comment on LA-run supplies (as derived from appendices) None of the zones achieved protozoal compliance; the optimal means of achieving protozoal compliance needs to be determined and implemented. There was a decline in overall bacteriological compliance since 2007/8. The three supplies that did not comply did so because of E. coli transgressions and failure to adequately follow up E. coli transgressions with corrective action. This is a serious matter and needs to be addressed promptly. The presence of E. coli in water indicates that the supply is contaminated with faeces and that water treatment is not adequately removing the ensuing risk of waterborne disease. Failure to implement immediate corrective action means that the consumers are exposed to continued risk of waterborne disease. Chemical compliance was achieved for the single supply to which a P2 determinand was assigned.

General comment on LA-run supplies (as derived from appendices) Protozoal compliance was achieved in only one zone during the past year. While this is an improvement, the optimal means of achieving protozoal compliance needs to be determined and implemented for the remaining supplies. Overall bacteriological compliance has not changed during the past year. Two supplies did not comply due to excess E. coli transgressions, one of these with inadequate corrective actions. This is a serious matter and needs to be addressed promptly. The presence of E. coli in water indicates that the supply is contaminated with faeces and that water treatment is not adequately removing the ensuing risk of waterborne disease. Failure to implement immediate corrective action means that the consumers are exposed to continued risk of waterborne disease. One supply failed to comply because of inadequate monitoring. Attention to the maximum interval between successive samples and minimum days-of-the-week criteria is needed if compliance is to be achieved for these supplies. Raetihi has experienced problems with disinfection by-products exceeding their MAVs this year. Changes in the catchment that have increased the concentrations of natural organics, extreme weather conditions, or perhaps poorer of control of treatment processes may have caused this. The reasons for the non-compliances should be identified and actions taken to reduce the likelihood of the transgressions. Careful timetabling of the sampling for fluoride at the Taumarinui treatment plant should ensure compliance in future.

Bacteriological compliance improved during the past year. Three supplies did not comply because of E. coli transgressions, the reasons for which need to be investigated and resolved. Non-compliance in the remaining supply was caused by inadequate monitoring. Attention to the maximum interval between samples criterion is needed if compliance is to be achieved for this supply. Careful timetabling of the sampling for fluoride at the Tokoroa treatment plant should ensure compliance in future.

General comment on LA-run supplies (as derived from appendices) Protozoal compliance improved during the past year and was achieved in four plants and three zones; the optimal means of achieving protozoal compliance needs to be determined and implemented. Zone bacteriological compliance improved slightly during the past year. Monitoring programmes still need to be established for the unmonitored supplies. It is not acceptable for LA-run supplies to be not monitored. Chemical compliance was not achieved at Tairua because no sampling was undertaken. A monitoring programme should be put in place.

General comment on LA-run supplies (as derived from appendices) Ten supplies were bacteriologically-compliant during the past year, which represents a significant improvement. However, three supplies did not comply due to excess E. coli transgressions, one of these with inadequate corrective actions. This is a serious matter and needs to be addressed promptly. The presence of E. coli in water indicates that the supply is contaminated with faeces and that water treatment is not adequately removing the ensuing risk of waterborne disease. Failure to implement immediate corrective action means that the consumers are exposed to continued risk of waterborne disease. Attention to the bacteriological monitoring requirements is required for compliance to be achieved in the other three supplies. Other than the zones served by the Hamilton City treatment plant at Waiora Terrace, none of the supplies achieved protozoal compliance. The optimal means of achieving protozoal compliance should be determined for the non-complying supplies. Steps should be taken at Newstead to demonstrate that lead arises due to plumbosolvency so that they it be reclassified as a P3 determinand, and the need to monitor it can cease. Improved control of fluoride dosing is required to overcome the fluoride transgressions at TP00132. Careful timetabling of the sampling for arsenic at Kauwhata should ensure compliance in future.

General comment on LA-run supplies (as derived from appendices) The council is commended for maintaining complete bacteriological compliance achieved during the past year. None of the supplies achieved protozoal compliance during the past year. The optimal means of achieving protozoal compliance should be determined and implemented. All supplies were chemically compliant except Pirongia. If the lead can be shown to arise from plumbosolvency of the water, the need for its monitoring can be eliminated provided the necessary public warnings to flush taps before drawing water for consumption are given.

General comment on supplies (as derived from appendices) LA-run supplies - Most of the rural supplies do not achieve protozoal compliance; for these supplies the optimal means of achieving protozoal compliance should be determined. Monitoring for P2 determinands (mostly metals) is inadequate in many supplies. If water suppliers carry out the monitoring required to show that the metals arise from plumbosolvency, the need to monitor for these determinands can be eliminated provided the necessary public warnings to flush taps before drawing water for consumption are given. School/ECC supplies - School/ECC supplies - monitoring programmes need to be established in most of these supplies in the Pacific Health region; a lead by the DHB is suggested. Excess E. coli transgressions occurred in three schools; it would be helpful to determine whether additional treatment or improved procedures are required and, if the former, to advise the Ministry of Education. Many other schools/ECCs are not monitored enough; it would be useful for the DHB to ascertain and remedy the impediments to full monitoring. Other supplies - a large proportion are not monitored; some initiative by the DHB may be required to improve this situation.

General comment on LA-run supplies (as derived from appendices) Neither of the zones achieved protozoal compliance; the optimal means of achieving protozoal compliance needs to be determined and implemented. Bacteriological non-compliance was caused in one zone by excess E.coli transgressions, the cause of which needs to be determined and remedied. Both supplies were inadequately monitored; more attention will need to be paid to the monitoring requirements if these supplies are to achieve compliance in future. Compliance was not achieved for either of the two supplies to which P2 determinands were assigned, because of too few samples being taken. An adequate monitoring programmes should be put in place for arsenic. If the metals can be shown to arise from plumbosolvency of the water, the need for their monitoring can be eliminated provided the necessary public warnings to flush taps before drawing water for consumption are given.

General comment on LA-run supplies (as derived from appendices) None of the zones complied with the protozoal requirements; the optimal means of achieving protozoal compliance needs to be determined and implemented. A single non-compliant supply was caused by excess E. coli transgressions, the cause of which should be investigated and remedied. Chemical compliance was not achieved for any of the heavy metals assigned to Kaingaroa. Steps should be taken to demonstrate that these metals arise due to plumbosolvency so that they can be reclassified as P3 determinands, and the need to monitor them can cease.

General comment on LA-run supplies (as derived from appendices) None of the LA-run zones complied with the protozoal requirements during the past year; the optimal means of achieving protozoal compliance needs to be determined and implemented. There is a high degree of bacteriological compliance in the supplies. However, the Whakamoenga Point supply had excess E. coli transgressions and the Tokaanu supply was inadequately monitored. An additional six supplies failed to take sufficient monitoring samples during one quarter but were given leniency; steps should be taken to ensure this problem does not recur as this would affect compliance. Although several P2 determinands were shown to be compliant, several supplies were non-compliant for arsenic because of transgressions. Advice should be sought to determine how the concentration of this determinand could be reduced. Careful timetabling of the sampling for fluoride at TP00011 should ensure compliance in future.

General comment on LA-run supplies (as derived from appendices) The council is commended for achieving bacteriological compliance during the past year. Both of the larger supplies were adequately treated for protozoa but the two smaller supplies did not receive adequate protozoa treatment. The McLarens Falls Park supply is an independent water supply servicing ranger houses and a picnic spot outside the Tauranga City Council boundary and is not associated with the Tauranga City reticulated supply. No supplies required P2 determinand monitoring.

General comment on LA-run supplies (as derived from appendices) The council is commended for achieving complete bacteriological compliance during the past year. It is noted that the Ruatahuna Village supply is no longer operated by the council. However, the details of the new ownership will need to be notified before this supply can be removed from the council supply set. None of the zones complied with the protozoal requirements; the optimal means of achieving protozoal compliance needs to be determined and implemented. Thornton and Edgecumbe were non-compliant for arsenic because of the high arsenic concentration. Advice should be sought on ways of reducing the arsenic in these systems. Inadequate monitoring has resulted in the chemical non-compliance in a number of supplies. Steps should be taken to demonstrate that metals arise due to plumbosolvency so that they can be reclassified as P3 determinands, and the need to monitor them can cease.

General comment on LA-run supplies (as derived from appendices) The Gisborne City zone failed to achieve protozoal compliance during the past year because of a malfunction in the Waipaoa plant, which was on line for less than two weeks in December. Bacteriological compliance was achieved in two supplies during the past year. The Whatatutu supply had excess bacteriological transgressions, the cause of which should be investigated and remedied. A monitoring programme needs to be re-established for the Blue Water Reserve supply. Compliance for fluoride was achieved for the Gisborne supply, but Te Karaka was non-compliant because of manganese transgressions. Steps should be taken to reduce the manganese concentration in the water.

General comment on supplies (as derived from appendices) LA-run supplies - Protozoal compliance was achieved in the New Plymouth zones - the optimal means of achieving protozoal compliance should be determined for the Stratford and South Taranaki supplies. ☺ New Plymouth and Stratford District Councils are commended for achieving complete bacteriological compliance in their supplies during the past year. / Bacteriological compliance declined in the South Taranaki district - more attention to the monitoring requirements is needed. School/ECC supplies - The water quality of Taranaki school supplies has continued to improve incrementally this year. Four schools did not monitor their water quality; the DHB should investigate the reasons for this so that a suitable approach may be developed to help initiate monitoring programmes. Other supplies - a large proportion are not monitored; some additional encouragement may be warranted.

General comment on supplies (as derived from appendices) LA-run supplies - Protozoal compliance was not achieved in many of the supplies; the optimal means of achieving protozoal compliance should be determined for these supplies. Bacteriological complience has improved markedly during the past year. School/ECC supplies - While compliance remains low, the number of schools not monitoring their water supplies fell markedly during the past year. Most of the other supplies were not monitored often enough; the DHB should ascertain and report the impediments to full monitoring in the remaining schools. The number of schools reporting E. coli contamination and inadequate corrective action remained unchanged since the previous year and most of these did not follow up transgressions with adequate corrective actions. This is of great concern as it places children at elevated risk of waterborne disease. It is recommended that the DHB determine whether additional treatment or improved procedures are required and, where appropriate, to advise the Ministry of Education. Further education of the operators about the public health significance of drinking E. coli -contaminated water is recommended. Other supplies - a large proportion remain unmonitored.

General comment on LA-run supplies (as derived from appendices) None of the zones achieved protozoal compliance during the past year; the optimal means of achieving protozoal compliance should be determined. Overall bacteriological compliance of the supplies remained the same during the past year. The two non- compliant supplies were inadequately monitoring; attention will need to be paid to the monitoring requirements if compliance is to be achieved in future. No supplies required P2 determinand monitoring.

General comment on supplies (as derived from appendices) Protozoal compliance was not achieved in most of the supplies; the optimal means of achieving protozoal compliance should be determined for the remainder. LA-run supplies - The hitherto improving trend towards bacteriological compliance was reversed during the past year. ☺ Palmerston North City and Rangitikei District Councils are commended for attaining/maintaining complete bacteriological compliance. School/ECC supplies - 16 schools did not monitor their water quality, a large improvement. Bacteriological failures occurred in 11 supplies; It is recommended that the DHB determine whether additional treatment or improved procedures are required and, where appropriate, to advise the Ministry of Education. In addition, four of these schools/ECCs did not carry out appropriate corrective actions following an E. coli transgression, which is of great concern. Further education of the operators about the public health significance of drinking E. coli -contaminated water is recommended. Other supplies - most of the private supplies in the Manawatu except those in Palmerston North were not monitored; further encouragement would apper to be warranted.

General comment on LA-run supplies (as derived from appendices) The perfect record of bacteriological compliance declined to no compliance during the past year. This was caused by inadequate monitoring in all of the LA-run supplies. More attention needs to be paid to the monitoring schedule, particularly the maximum interval criterion, if these supplies are to comply in future. None of the zones achieved protozoal compliance; the optimal means of achieving protozoal compliance should be determined and implemented. Tokomaru and Shannon were non-compliant for haloacetic acids because of transgressions. Advice should be sought to determine what steps can be taken to reduce the concentrations of these determinands in the water.

General comment on LA-run supplies (as derived from appendices) Protozoal compliance was achieved in only one zone during the past year. While this is an improvement, the optimal means of achieving protozoal compliance needs to be determined and implemented for the remaining supplies. Overall bacteriological compliance has not changed during the past year. Two supplies did not comply due to excess E. coli transgressions, one of these with inadequate corrective actions. This is a serious matter and needs to be addressed promptly. The presence of E. coli in water indicates that the supply is contaminated with faeces and that water treatment is not adequately removing the ensuing risk of waterborne disease. Failure to implement immediate corrective action means that the consumers are exposed to continued risk of waterborne disease. One supply failed to comply because of inadequate monitoring. Attention to the maximum interval between successive samples and minimum days-of-the-week criteria is needed if compliance is to be achieved for these supplies. Raetihi has experienced problems with disinfection by-products exceeding their MAVs this year. Changes in the catchment that have increased the concentrations of natural organics, extreme weather conditions, or perhaps poorer of control of treatment processes may have caused this. The reasons for the non-compliances should be identified and actions taken to reduce the likelihood of the transgressions. Careful timetabling of the sampling for fluoride at the Taumarinui treatment plant should ensure compliance in future.

General comment on LA-run supplies (as derived from appendices) None of the zones achieved protozoal compliance; the optimal means of achieving protozoal compliance needs to be determined and implemented. Bacteriological compliance regressed during year, with excess E. coli transgressions being the cause for all three of the non-compliant supplies. The cause of the transgressions needs to be investigated and remedied. Both supplies to which P2 determinands have been assigned were non-compliant because of disinfection by- product transgressions. Advice should be sought as to how the concentrations of these determinands can be reduced.

General comment on LA-run supplies (as derived from appendices) Protozoal compliance improved during the past year, with compliance being achieved in seven plants serving eight zones. The optimal means of achieving protozoal compliance needs to be determined and implemented for the remaining supplies. Bacteriological compliance declined during the past year, with excess E. coli transgressions in three supplies and the Otumaire Camp supply was again inadequately monitored. The cause of the E. coli transgressions needs to be investiagted and remedied. No supplies required P2 determinand monitoring.

General comment on supplies (as derived from appendices) LA-run supplies - Protozoal compliance was seldom achieved outside the main centres; the optimal means of achieving protozoal compliance should be determined for these supplies. ☺ Carterton, Kapiti Coast and Masterton District Councils and Porirua, The Hutt, Upper Hutt and Wellington City Councils are commended for achieving bacteriological compliance in all their supplies during the past year. School/ECC supplies - Compliance of school supplies improved during the past year, as did monitoring overall. Other supplies - Many supplies continue to be unmonitored; further encouragement may be useful to improve this aspect.

General comment on LA-run supplies (as derived from appendices) None of the zones achieved protozoal compliance; the optimal means of achieving protozoal compliance should be determined. Bacteriological compliance has improved during the past year, with compliance being achieved in three of the four supplies. The Lake Ferry Camping Ground supply failed to comply due to inadequate monitoring. Two supplies were not chemically compliant, because of no, or inadequate, monitoring in both cases. An adequate monitoring programme should be put in place for haloacetic acids at Featherston, and steps should be taken in all supplies with metal P2 determinands to demonstrate that the metals arise due to plumbosolvency so that they can be reclassified as P3 determinands, and the need to monitor them can cease.

General comment on supplies (as derived from appendices) LA-run supplies - overall, protozoal compliance has not changed but bacteriological compliance has declined during the past year. Protozoal compliance was not achieved in most of the rural supplies; the optimal means of achieving protozoal compliance should be determined for these supplies. / Two of the Marlborough District Council zones failed due to excess E. coli transgressions and inadequate corrective action; these need to be investigated and addressed promptly and, as this was also noted in the previous report, the DWA is requested to investigate and report progress to the Ministry of Health (see DWA comment). School/ECC supplies - the trend of improved compliance of school supplies continued during the past year, but the monitoring declined slightly. Other supplies - Most supplies continue to be unmonitored; further encouragement may be useful to improve this aspect. DWA Comment - these two LA-run zones are on a permanent boil water notice and treatment of the scheme has been extensively discussed with the community and Ministry of Health. Treatment options are being assessed.

General comment on LA-run supplies (as derived from appendices) None of the zones achieved protozoal compliance; the optimal means of achieving protozoal compliance should be determined and implemented for these supplies. Bacteriological compliance declined slightly during the past year, with compliance being achieved in five of the eight zones. Excess E. coli transgressions and inadequate corrective actions occurred in two zones. The presence of E. coli in water indicates that the supply is contaminated with faeces and that water treatment is not adequately removing the ensuing risk of waterborne disease. Failure to implement immediate corrective action means that the consumers are exposed to continued risk of waterborne disease. The same situation was noted in the previous report - this is a serious matter and needs to be dealt with urgently (see DWA comment) . Failure to account for the maximum interval between samples was the cause on non-compliance in the Havelock supply. Chemical compliance was not achieved for two supplies because of no, or inadequate, monitoring of metals. Steps should be taken to demonstrate that these metals arise due to plumbosolvency so that they can be reclassified as P3 determinands, and the need to monitor them can cease.

DWA Comment - The same situation was noted in the previous report. Since then extensive consultation with the community has been undertaken, treatment options are being assessed and Capital Assistance Programme funds will be sought.

General comment on LA-run supplies (as derived from appendices) None of the zones achieved protozoal compliance; the optimal means of achieving protozoal compliance should be determined and implemented for these supplies. Bacteriological compliance has declined during the past year. Excess E. coli transgressions occurred in three supplies; these need to be investigated to determine whether treatment or process controls need to be improved. One transgression was not followed up by adequate corrective action; the water supplier is advised to implement the corrective action procedure following E. coli transgressions as described in Figure 4.2 of the DWS 2005. One supply was not monitored; a monitoring programme needs to be established for the Torrent Bay Village supply as it is not acceptable for LA-run supplies to be not monitored. Two supplies were non-compliant for heavy metals because if inadequate monitoring. Richmond was non- compliant because of nitrate exceeding its MAV. Steps should be taken to demonstrate that the metals arise due to plumbosolvency so that they can be reclassified as P3 determinands, and the need to monitor them can cease. Ways in which the nitrate problem in Richmond should also be investigated, if this has not already been done.

General comment on supplies (as derived from appendices) LA-run supplies - Protozoal compliance was not achieved in most of the rural supplies; the optimal means of achieving protozoal compliance should be determined for these supplies. Monitoring of P2 determinands has been poor in several districts. Where suppliers are reluctant to monitor for P2 metals, the need to monitor for these determinands can be eliminated (provided the necessary public warnings to flush taps before drawing water for consumption are given), if the suppliers carry out the monitoring required to show that the metals arise from plumbosolvency. Bacteriological compliance improved overall in LA-run supplies during the past year. / The Buller, Hurunui, Selwyn and Waimate District Councils need to take appropriate corrective action following E. coli transgressions. It is suggested that these councils be reminded of the public health significance of faecally-contaminated drinking-water. As this was also noted in the previous report, the DWA is requested to investigate and report progress to the Ministry of Health. School/ECC supplies - The number of school/ECCs supplies with E. coli transgressions halved to four during the past year and all of these implemented adequate corrective action, which is much improved over the previous year. The number of unmonitored school/ECCs supplies increased during the year and 14 were not still monitored. These matters warrant attention by the DHB/Ministry of Education. Other supplies - a large number of these supplies were not monitored or were contaminated with E. coli .

General comment on LA-run supplies (as derived from appendices) Protozoal compliance was achieved in three zones. The optimal means of achieving protozoal compliance needs to be determined and implemented for the remaining supplies. The trend of improving bacteriological compliance has continued. The sole non-compliant supply was inadequately monitored. Addressing this should result in full bacteriological compliance could be achieved next year if the deficiencies in the Methven/Springfield monitoring programme were to be addressed. All supplies having to monitor P2 determinands were chemically compliant.

General comment on LA-run supplies (as derived from appendices) None of the zones achieved protozoal compliance; the optimal means of achieving protozoal compliance should be determined. Bacteriological compliance has declined to zero during the past year. Excess E. coli transgressions occurred in two supplies with inadequate corrective actions in two of these. The presence of E. coli in water indicates that the supply is contaminated with faeces and that water treatment is not adequately removing the ensuing risk of waterborne disease. Failure to implement immediate corrective action means that the consumers are exposed to continued risk of waterborne disease. The cause of E. coli in these supplies should be investigated and remedied. The same three unmonitored supplies in 2005, 2006/7 and 2007/8 were again not monitored during 2008/9. Establishment of monitoring programmes for these supplies is long overdue - it is not acceptable for LA-run supplies to be unmonitored. All supplies having to monitor P2 determinands were chemically compliant, except Reefton which was non- compliant because of inadequate monitoring of heavy metals. Antimony is present in the source water. A satisfactory monitoring programme needs to be put in place for it, and plans made for how its concentration might be reduced. However, for lead, steps should be taken to demonstrate that it arises due to plumbosolvency so that it can be reclassified as P3 determinands, and the need to monitor them can cease.

General comment on LA-run supplies (as derived from appendices) Protozoal compliance is has improved slightly during the past year, with protozoal compliance being achieved by seven plants serving nine zones. The optimal means of achieving protozoal compliance should be determined and implemented for the remainder. Bacteriological compliance improved markedly during the past year, with only one non-compliant supply. The caues of the excess E. coli transgressions in the Wainui zone should be investigated and remedied. All supplies having to monitor P2 determinands were chemically compliant, with the exception of the Alymers Zone in Akaroa, where there was inadequate monitoring for chlorate and transgressions for the haloacetic acids. A monitoring programme must be put in place for chlorate, and, if not already done, advice should be sought as to how the haloactic acid concentrations might be reduced.

General comment on LA-run supplies (as derived from appendices) The quality of drinking-water in the Hurunui district is generally very poor. None of the zones achieved protozoal compliance; the optimal means of achieving protozoal compliance should be determined and implemented. Bacteriological compliance has declined further during the past year. Many of the supplies are in need of effective treatment - excess E. coli transgressions occurred in 20 supplies, with three of these not following appropriate corrective action procedures. The same situation was noted in the previous report - this is a serious matter and needs to be dealt with urgently. The presence of E. coli in water indicates that the supply is contaminated with faeces and that water treatment is not adequately removing the ensuing risk of waterborne disease. Failure to implement immediate corrective action means that the consumers are exposed to continued risk of waterborne disease. Three supplies were chemically non-compliant because there was no monitoring of P2 metal determinands. Steps should be taken to demonstrate that these metals arise due to plumbosolvency so that they can be reclassified as P3 determinands, and the need to monitor them can cease.

General comment on LA-run supplies (as derived from appendices) The council is commended for achieving protozoal compliance in two zones during the past year. The optimal means of achieving protozoal compliance should be determined and implemented in the remainder. Bacteriological compliance has declined during the past year, with four zones now complying. Excess E. coli transgressions occurred in the Kaikoura Urban and South Bay zones, the causes of which should be investigated and remedied. Three zones failed to comply because of inadequate monitoring. No supplies required P2 determinand monitoring.

General comment on LA-run supplies (as derived from appendices) None of the zones achieved protozoal compliance; the optimal means of achieving protozoal compliance should be determined and implemented. Bacteriological compliance improved during the past year, with three zones now compliant. Excess E. coli transgressions occurred in the Twizel, Allandale and Burke's Pass supplies. The presence of E. coli in water indicates that the supply is contaminated with faeces and that water treatment is not adequately removing the ensuing risk of waterborne disease. The cause of the transgressions should be investigated and remedied. Twizel and Fairlie were chemically non-compliant because metal P2 determinands were not monitored. Steps should be taken to demonstrate that these metals arise due to plumbosolvency so that they can be reclassified as P3 determinands, and the need to monitor them can cease.

General comment on LA-run supplies (as derived from appendices) Protozoal compliance was achieved in 12 plants and eight zones, which represents a slight improvement over the previous year. The optimal means of achieving protozoal compliance should be determined and implemented for the remaining supplies. Bacteriological compliance has improved in the past year, with 18 zones now compliant. Excess E. coli transgressions occurred in eight* supplies, with five of these not following appropriate corrective action procedures. This needs to be addressed as a matter of urgency. The presence of E. coli in water indicates that the supply is contaminated with faeces and that water treatment is not adequately removing the ensuing risk of waterborne disease. Failure to implement immediate corrective action means that the consumers are exposed to continued risk of waterborne disease. The Upper Selwyn Huts supply was still not monitored; a monitoring programme needs to be established for this supply as it is not acceptable for LA-run supplies to be unmonitored. The single supply having to monitor P2 determinands was chemically compliant.

* There is some uncertainty regarding the validity of the E. coli transgression recorded in the Edendale, Sandy Knolls zone, which resulted in the zone to be recorded as bacteriologically non-compliant. This was caused by incomplete confirmation of a single E. coli result by the laboratory.

General comment on LA-run supplies (as derived from appendices) Protozoal compliance remained unchanged since the previous year and was achieved in one plant serving two zones. The optimal means of achieving protozoal compliance should be determined and implemented for the remaining supplies. Bacteriological compliance increased during the past year. Excess E. coli transgressions occurred in the Peel Forest supply. The cause of the transgression needs to be investigated and remedied. A monitoring programme still needs to be established for the newly registered Landsborough Holme Station supply. No supplies required P2 determinand monitoring.

General comment on LA-run supplies (as derived from appendices) There has been a large improvement in protozoal compliance during the past year, for which the council is commended. The optimal means of achieving protozoal compliance should be determined and implemented for the remainding supplies. There was a slight improvement in bacteriological compliance during the past year. More monitoring is required to achieve compliance for the Woodend supply. Monitoring was discontinued in the Mandeville Sports Club supply during 2006/7. It is understood that this supply is no longer run by the LA and needs to be re-registered as a non-LA supply. No supplies required P2 determinand monitoring.

General comment on LA-run supplies (as derived from appendices) None of the zones achieved protozoal compliance; the optimal means of achieving protozoal compliance should be determined and implemented. Excess E. coli transgressions occurred in three supplies, with none of these following appropriate corrective action procedures. This needs to be addressed as a matter of urgency. The presence of E. coli in water indicates that the supply is contaminated with faeces and that water treatment is not adequately removing the ensuing risk of waterborne disease. Failure to implement immediate corrective action means that the consumers are exposed to continued risk of waterborne disease. These supplies need to be investigated to determine whether treatment or process controls need to be improved. The Briars Gully Camp and Hook/Waimate supplies were not monitored during the survey year; the water supplier needs to establish monitoring programmes for these supplies. It is advised that CPH conduct surveillance sampling on these supplies during the forthcoming year. All supplies were chemically compliant by virtue of there being no P2s assigned in the Waimate district.

The presence of E. coli in water indicates that the supply is contaminated with faeces and that water treatment is not adequately removing the ensuing risk of waterborne disease. Effective treatment needs to be installed for these supplies. Hokitika failed to comply due to inadequate monitoring. Two supplies that were not monitored last year were again not monitored. This is unacceptable for LA-run supplies; monitoring programmes must be established for these supplies. It is advised that CPH conduct surveillance sampling on these supplies during the forthcoming year.

General comment on supplies (as derived from appendices) LA-run supplies - Throughout Otago and Southland, protozoal compliance was achieved in only six LA-run plants serving 13 zones in Dunedin and Oamaru; the optimal means of achieving protozoal compliance should be determined and implemented for the remaining supplies. bacteriological compliance has improved overall in LA-run supplies during the past year. / Waitaki District Council needs to take appropriate corrective action following all E. coli transgressions. It is suggested that the council be reminded of the public health significance of faecally-contaminated drinking- water and, as this was also noted in the previous report, the DWA is requested to investigate and report progress to the Ministry of Health. / P2 metals were again not monitored by Waitaki District Council. It is suggested that the council be reminded that if these metals are corrosion-derived the need to monitoring for these determinands can be eliminated (provided the necessary public warnings to flush taps before drawing water for consumption are given), if the suppliers carry out the monitoring required to show that the metals arise from plumbosolvency. School/ECC supplies - overall, the bacteriological compliance has declined markedly for school supplies. The reasons for this should be ascertained and reported to the Ministry. All except two schools were monitored but nine schools reported E. coli in their water supplies during the past year. Other supplies - the large number of supplies in this category are still not monitored or contaminated with E. coli .

General comment on LA-run supplies (as derived from appendices) None of the zones achieved protozoal compliance; the optimal means of achieving protozoal compliance should be determined and implemented. Bacteriological compliance remains the same as last year, with five supplies complying. Excess E. coli transgressions occurred in the Alexandra supply. The presence of E. coli in water indicates that the supply is contaminated with faeces and that water treatment is not adequately removing the ensuing risk of waterborne disease. This needs to be investigated to determine whether treatment or process controls need to be improved. Six supplies were inadequately monitored. The monitoring criteria need to be addressed if compliance to be achieved in future. Ranfurly was not chemically compliant because chlorate was not monitored in the supply. A monitoring programme for this determinand should be designed and implemented.

General comment on LA-run supplies (as derived from appendices) None of the zones achieved protozoal compliance; the optimal means of achieving protozoal compliance should be determined and implemented. The number of bacteriologically complying zones did not improve during the past year, although there was a substantial improvement in terms of the population in complying zones. Excess E. coli transgressions occurred in 10 supplies during the past year. The presence of E. coli in water indicates that the supply is contaminated with faeces and that water treatment is not adequately removing the ensuing risk of waterborne disease. Monitoring was still deficient in several supplies, which needs to be addressed if they are to achieve compliance. Three supplies were not chemically compliant. Monitoring of fluoride was adequate in the Balclutha supply, with two transgressions. Steps should be taken to ensure better control of the fluoride dosing. The remaining non-compliant P2 assignations were disinfection by-products, and no attempt was made to monitor them. An adequate montoring progamme should be put in place for these determinands, to improve the likelihood of compliance with the DWSNZ.

General comment on LA-run supplies (as derived from appendices) Protozoal compliance is steadily improving and was achieved in five plants serving eight zones during the past year. Bacteriological compliance declined during the past year. Excess E. coli transgressions occurred in the Rocklands/Shannon/Pukerangi. The presence of E. coli in water indicates that the supply is contaminated with faeces and that water treatment is not adequately removing the ensuing risk of waterborne disease. The Booth Road supply was inadequately monitored. Attention needs to be paid to the maximum interval between successive samples this year if the two zones that were given leniency in this respect are to retain their compliance. All supplies having to monitor P2 determinands were chemically compliant, except Waitati which suffered a transgression for one of the haloacetic acids. Haloacetic acid transgression have occurred in the past. Advice should be sought as to how haloacetic acid concentrations might be reduced.

Bacteriological compliance has declined again during the past year, with four zones not complying. Excess E. coli transgressions occurred in the Hawea supply. The presence of E. coli in water indicates that the supply is contaminated with faeces and that water treatment is not adequately removing the ensuing risk of waterborne disease. The Glendhu Bay Motor Camp supply was not still monitored. A monitoring programme needs to be established this supply as it is not acceptable for LA-run supplies to be unmonitored. (If this supply is no longer run by QLDC please advise ESR of the water supplier's details.) The Lake Hayes and Albert Town supplies were inadequately monitored. The single supply having to monitor P2 determinands was chemically compliant.

General comment on LA-run supplies (as derived from appendices) None of the zones or plants achieved protozoal compliance; the optimal means of achieving protozoal compliance should be determined and implemented. There was a slight increase in overall in bacteriological compliance during the past year with compliance being achieved in only eight zones. Excess E. coli transgressions occurred in the Otahu Flat and Orawia supplies, the causes for which need to be investigated and remedied. The presence of E. coli in water indicates that the supply is contaminated with faeces and that water treatment is not adequately removing the ensuing risk of waterborne disease. The other zones were inadequately monitored; their monitoring programmes need to be revised if they are to comply next year. All supplies having to monitor P2 determinands were chemically compliant.

General comment on LA-run supplies (as derived from appendices) The council is commended for achieving protozoal compliance in the Oamaru supply. However, none of the other supplies achieved protozoal compliance; the optimal means of achieving protozoal compliance should be determined and implemented. Bacteriological compliance increased slightly during the past year, with 15 supplies now complying. Excess E. coli transgressions occurred in 14 supplies, of which appropriate corrective actions were not followed in seven. This is being addressed in four of the supplies for which treatment is planned but needs to be addressed as a matter of urgency for the other supplies. The presence of E. coli in water indicates that the supply is contaminated with faeces and that water treatment is not adequately removing the ensuing risk of waterborne disease. Failure to implement immediate corrective action means that the consumers are exposed to continued risk of waterborne disease. Eight supplies were also inadequately monitored. More attention needs to be paid to the monitoring criteria if compliance is to be achieved in future. A monitoring programme for the recently-registered Oamaru Central zone has now been established. Kakanui and Palmerston supplies were chemically non-compliant with respect to heavy metals as no monitoring was undertaken. Steps should be taken to demonstrate that these metals arise due to plumbosolvency so that they can be reclassified as P3 determinands, and the need to monitor them can cease.

# Similar poor practice reported in 2007/8 review.

The presence of E. coli in water indicates that the supply is contaminated with faeces and that water treatment is not adequately removing the ensuing risk of waterborne disease. Failure to implement immediate corrective action means that the consumers are exposed to continued risk of waterborne disease. This risk will be exacerbated if the level of disease in the animals/people in the drinking-water catchment area is higher than normal.
