EXECUTIVE SUMMARY
Under the BC Drinking Water Protection Act and Drinking Water Protection Regulation it is the City’s responsibility to continually monitor drinking water quality, and create summarized reports illustrating these results and making them available to the public. This report summarizes the monitoring under the City of Coquitlam drinking water monitoring program and documents the effectiveness of the barriers in place to protect water quality for the year 2020.
Out of over two thousand samples taken in 2020, with only four water samples testing positive for non-fecal coliform bacteria. Out of the four positive coliform samples, one contained greater than the allowable criteria of no more than 10 total coliform per 100 ml. The City took action immediately and rectified the situation resulting in consecutive tests reading below the Regulation criteria. At no point did the City of Coquitlam exceed the 10% of samples showing the presence of coliform in a 30 day period permitted by the Safe Drinking Water Regulation.
All drinking water samples have come within the acceptable levels of concentrations of disinfection bi-products (DBP’s), metals, and vinyl chlorides as established by the Guidelines for Canadian Drinking Water Quality.
The City has recorded 44 water quality complaints in 2020. The majority of these were due to turbidity caused by normal operation and maintenance activities, and usually cleared up within 2 hours of the initial call.
Message from the Health Protection Manager
“Anytime the water in a particular faucet has not been used for six hours or longer, “flush” your cold-water pipes by running the water until you notice a change in temperature. (This could take as little as five to thirty seconds if there has been recent heavy water use such as showering or toilet flushing. Otherwise, it could take two minutes or longer.) The more time water has been sitting in your home’s pipes, the more lead it may contain.
Use only water from the cold-tap for drinking, cooking, and especially making baby formula. Hot water is likely to contain higher levels of lead.
The two actions recommended above are very important to the health of your family. They will probably be effective in reducing lead levels because most of the lead in household water usually comes from the plumbing in your house, not from the local water supply.
Conserving water is still important. Rather than just running the water down the drain you could use the water for things such as watering your plants.”
While the above message from the Health Protection Manager is good precautionary advice, it has more prominence in older communities that had widespread use of lead pipe & solder in their plumbing systems. Metro Vancouver also maintains water pH above 6.5 to control corrosion, which reduces the leaching of lead and copper into the water supply.
Emergency Response Plan
The City water utility is included in the Public Works Response Plan and Division Operation Centre Guidelines. The plan can be viewed on the City’s website; https://www.coquitlam.ca/DocumentCenter/View/447/Public-Works-Response-Plan-and- Division-Operation-Centre-Guidelines

2020 Annual Drinking Water Quality Report
INTRODUCTION
The Province of British Columbia has regulations set out in the Drinking Water Protection Act and the Drinking Water Protection Regulation. The Act establishes the requirements for operators and suppliers of drinking water to ensure the public are provided with safe drinking water. Along with the Act, the Regulation sets out minimum safety standards to be met for water treatment and sampling, further establishing a set of regulations for the operation and monitoring of water distribution systems. These regulations, along with emergency response plans, provide the public protection from water borne harmful bacteria or any contamination that may be hazardous to the public’s health.
The Regulation stipulates in Section 8, Water Monitoring Analysis, that a supplier must collect and test samples from their distribution system as directed by a drinking water officer. In July 1998 the Lower Mainland Medical Health Officers issued the “Water Quality Monitoring Protocol” outlining the Health Officer’s requirements for water purveyors in the Greater Vancouver area.
Similar to most of the municipalities in the region, the City of Coquitlam does not have a water supply treatment facility and instead purchases treated potable water from the Greater Vancouver Water District (Metro Vancouver). To coordinate the efforts of the various municipalities with regard to distribution system testing, and to spell out their own responsibilities with regard to source water testing, Metro Vancouver in consultation with the Regional Health Officers, prepared the “Water Quality Monitoring and Reporting Plan for the GVRD and Member Municipalities”.
The Drinking Water Protection Act also requires that the results of a supplier’s water quality monitoring program must be reported publicly. Under Section 11 Time Limits for Publication, of the Regulation, it stipulates that a report must be published within six months of the end of each calendar year. This report will fulfill these requirements.
SOURCE WATER TESTING
All water distributed by the City’s water utility is purchased from Metro Vancouver and is supplied to the City primarily from two regional sources: Seymour Lake and Coquitlam Lake. Both these surface sources are treated by Metro Vancouver. As of January 2010, water distributed out of Seymour Lake goes through filtration and is disinfected using ultra violet light. The water distributed out of Coquitlam Lake is treated by both ozone and ultra violet light. Metro Vancouver also uses chlorine as a secondary disinfectant. The pH of the water at both Seymour and Coquitlam Lakes is also adjusted to make the water less acidic as a corrosion control measure. Supplies from both sources use chlorine as a secondary disinfectant. Despite the efforts of Metro Vancouver and the City of Coquitlam to provide disinfected drinking water, individuals with weakened immune systems are advised to read the Health Link BC Bulletin attached in Appendix l.
Quality of pre and post treated source water is monitored by Metro Vancouver in keeping with their water quality monitoring and reporting plan. The results of Metro Vancouver’s monitoring for 2020 can be found in their publication “Greater Vancouver Water District 2020 Water Quality Annual Report” attached as Appendix lI of this report.

DISTRIBUTION TESTING
As per the requirements of the Drinking Water Protection Regulation and to ultimately safe guard public health, the City must continuously test water quality throughout its distribution system. Under an agreement, and in correlation with Metro Vancouver’s Water Quality Monitoring and Reporting Plan, Metro Vancouver collects water samples for the City of Coquitlam and analyzes the samples at their Laboratory.
Metro Vancouver’s Laboratory is a member of the Canadian Association of Analytical Laboratories and is accredited by the Standards Council of Canada. The Provincial Health Officer also approves the Laboratory for the analysis of drinking water samples.
The weekly drinking water sample test results are forwarded to both the City of Coquitlam and the Fraser Health Authority directly by the Metro Vancouver’s Laboratory in accordance with the monitoring plan. If a sample shows evidence of fecal contamination, the Laboratory contacts both the City and the Fraser Health Region immediately via telephone in keeping with the requirements of Section 9, Immediate Reporting Standard, of the Drinking Water Protection Regulation to carry out the needed actions per set protocol.
Sampling Stations
There are 30 dedicated sampling stations distributed throughout the City. The station locations were chosen in consultation with the Fraser Health Authority and Metro Vancouver to provide a representative sample of drinking water quality throughout the entire distribution system. Figure 1 shows the geographic location of the sampling stations. Table 1 lists the sampling stations, their supply source, and flow rate at each location.

The monitoring protocol recommends the following distribution of sampling sites:
10% Supply 40% Low Flow 40% Medium Flow 10% Dead End.
The City’s current distribution is 0%, 40%, 30% and 30% respectively. The City has a disproportionate number of dead end and medium flow sites. This is due to the City’s sampling points being established prior to the creation of the current protocol. The sampling however represents water quality adequately. In addition, the City continuously makes effort to loop water mains to eliminate dead-ends through land development projects and City’s Capital projects.

2020 Annual Drinking Water Quality Report
Sampling Frequency
Schedule B of the Drinking Water Protection Regulation requires that the City take a minimum of 90 samples per month plus 1 sample per month for every 10,000 people in excess of 90,000. Coquitlam’s population estimate in 2020, per BC Stats, was 152,734. Under the protocol a minimum of 96 samples per month were required. The City’s lowest number of water samples taken in one month was 139, thus fulfilling the protocol.
Metro Vancouver collects samples from each sampling station on a weekly basis. Occasionally samples may not be collected due to malfunction of or damage to a station, or because a station could not be accessed. Table 2 summarizes the number of samples drawn each month as part of the Region’s scheduled sampling program.

Test Parameters
Weekly samples collected at each sampling site are tested for the following parameters:
Physical Parameters Temperature measured in degrees Celsius Free chlorine residual measured in milligrams per liter (mg/l) Turbidity measured in nephelometeric turbidity units (NTU)
Bacteriological Parameters Heterotrophic Plate Count (HPC) measured in colonies per milliliter Total coliform measured in organisms per 100 milliliters E. coli measured in organisms per 100 milliliters
The Region also collects water samples from selected stations each quarter, annually, for the following:
Disinfection Byproducts Halo acetic acids (HAA) measured in parts per billion (ppb) Trihalomethanes (THM) measured in parts per billion (ppb)
As well as semi-annually for the following: Metals measured in micrograms per liter (µ/L) Vinyl Chloride measured in milligrams per liter (mg/L) pH (acidity or alkalinity)

Regulations/Standards Distribution Testing
Schedule A, Water Quality Standards for Potable Water, of the Drinking Water Protection Regulation establishes that water samples must meet the following criteria:
Parameter: Standard:
Escherichia coli No detectable Escherichia coli per 100 ml
Total coliform bacteria (a) 1 sample in a 30 day period No detectable total coliform bacteria per 100 ml
(b) More than 1 sample in a 30 day period At least 90% of samples have no detectable total Coliform bacteria per 100 ml and; no sample has more than 10 total coliform bacteria per 100 ml
In addition to the legislated requirements, Water Quality Monitoring Protocol also states that samples should meet the standards for microbiology contained in the Guidelines for Canadian Drinking Water Quality published by Health Canada. With respect to Total Coliform the Guideline states:
“For distribution systems in public supplies where fewer than 10 samples are collected in a given sampling period, no sample should contain total coliform bacteria. In distribution systems where greater than 10 samples are collected in a given sampling period, no consecutive samples from the same site or not more than 10% of samples should show the presence of total coliform bacteria.
Testing for total coliforms should be carried out in all drinking water systems. The number, frequency, and location of samples for total coliform testing will vary according to the type and size of the system and jurisdictional requirements.”
Health Canada, the World Health Organization, and the US Environmental Protection Agency all now recognize that there are no negative health effects related to the presence of Heterotrophic bacteria in drinking water. The Heterotrophic Plate Count test is still conducted on samples drawn to give an indication of changes in the bacteriological environment of the water supplied.
Metro Vancouver’s Water Quality Monitoring and Reporting Plan requires testing for particular physical and chemical properties from the distribution system. Samples representative of each water source are required. The Canadian Safe Drinking Water Guideline limits, parameters to be monitored and sampling frequency are listed in Table 3 below.

E. Coli
In 2020 there were no samples drawn that tested positive for Escherichia coliform.
Total Coliform
Of the 2181 samples taken in 2020, four samples tested positive for coliforms from three stations: COQ-537, COQ-539 and COQ-601 (twice). Neither positive sample at COQ-537 and COQ-539 contained more total coliform than 10cfu/100mL. Results of one grab sample tested positive for total coliform greater than 10cfu/100mL. The grab sample from Station COQ-601 indicated 11 total coliform per 100mL. Once the City was notified, immediate work orders were executed to flush the identified system and rectify the situation. Within 24hrs, Metro Vancouver took a repeat 12
File #: 11-5210-01/000/2021-1 Doc #: 4095458.v1 2020 Annual Drinking Water Quality Report sample from COQ-601 and results indicated total coliform less than 10cfu/100mL. The follow up grab sample for COQ-601, indicated less than 1 total coliform per 100mL. These results illustrate that in 2020 the positive coliform samples did not exceed the 10% of samples in a 30 day period permitted by the Safe Drinking Water Regulation. Figure 2 displays the location of the sample stations throughout the City indicating positive coliform tests.
Figure 2: 2020 Sampling Stations Indicating Positive for Coliform
Chlorine Residuals
It is important to maintain a disinfectant residual in the distribution system in order to control the re-growth of bacteria. Metro Vancouver utilizes free chlorine residual as a disinfectant. Experience has shown that where a disinfectant residual of a minimum of 0.2 parts per million (milligrams per liter) is maintained, re-growth can be controlled.
Table 5 reports the total number of samples collected from each sampling point, the number of samples over 0.2 ppm of free chlorine and the number of samples with less than 0.2 ppm of free chlorine in 2020.

Figure 3: 2020 Chlorine Residuals
Stations COQ-612, 532, and 545 experienced chlorine residual levels below 0.2ppm in over 50% of samples taken. These three locations reside on Westwood Plateau, in areas that see little demand for water as they are located on low to dead-end water mains. These specific sampling stations are also located on the Plateau opposite of the reservoirs that serve them. The level of chlorination along the Plateau is moderated as in the past, high levels of chlorine in this area have contributed to resulting disinfection bi- products.
Chlorine residual at station COQ-601 was below 50% of samples >0.2ppm. This station is located at a dead-end main and City crews will continue to flush the lines and monitor closely to meet the 50% criteria.
Station COQ-543 usually straddles the line of 50% of samples >0.2ppm with 2020 results indicating exactly 50%. This is usually the case, due to this sampling location
15
File #: 11-5210-01/000/2021-1 Doc #: 4095458.v1 2020 Annual Drinking Water Quality Report being at the dead end of a lengthy water main. The City Public Works continue to monitor closely and flush lines when necessary.
2020 Results from station COQ-541 indicate 51% of samples taken were >0.2ppm total free chlorine. This is primarily due to the sample station being on one of the longest dead-end water mains within the City. The City has recently installed an automatic water main flushing system in this location to assist City crews. This innovative system allows automated scheduled flushing to occur that can be set by a timer, which allows for water to circulate more frequent at dead-end mains.
The City of Coquitlam is continuously reviewing development opportunities in order to loop water mains and reduce dead-end mains. Adding new technology such as the automatic water main flushing system will also assist with water circulation for dead- ends. In the meantime the City will continue monitoring chlorine residuals to control and minimize the re-growth of bacteria.
Disinfection Byproducts
The use of chlorine as a disinfectant for unfiltered source water can result in the creation of two families of potentially carcinogenic compounds: Trihalomethanes (THM’s) and Haloacetic acids (HAA’s). The Guidelines for Canadian Drinking Water Quality state that the running annual average total THM concentration should not exceed 100 parts per billion (ppb). In addition to concentration of bromodichlorimethane should not exceed 16 ppb. The Canadian Drinking Water Quality Guideline for HAA’s states that 80 ppb is the maximum acceptable concentration based on a locational annual running average of samples taken.
Table 6 below, represents the results of samples taken for the disinfection byproduct HAA. One sample result for HAA’s was 91ppb in the fourth quarter of 2020. Although it is above 80 ppb, the average running total for the four quarters is 58 ppb, which is well below the threshold established in the Guidelines for Canadian Drinking Water Quality. City staff will continue to monitor this site and make operational adjustments as needed.
All samples tested in 2020 were within the recommended guidelines for THMs. Results are summarized in Table 7. Staff will continue to use operational procedures such as using reduced reservoir levels in times of low water demand and adjusting the re-chlorination in times of high water demand to limit the generation of HAAs.

CUSTOMER COMPLAINTS
The City received 44 documented complaints regarding water quality in 2020. Most complaints are related to water turbidity due to flushing, valve exercising, or hydrant use/maintenance. The majority of these problems are resolved by home owners running their taps for 1 to 3 hours. Other complaints are usually related to odors which may be due to elevated chlorine levels when described as a chemical odor. When odor is described as skunky or sulfurous, stagnant water in hot water tanks or in the service line may be the source.
The City’s response to complaints varies with the nature and extent of the problem. Persistent turbidity problems related to the City distribution system are usually resolved by purging turbid water from the system by flushing.
The City responds to odor, taste or other customer specific complaints by conducting a site visit. Normally the problem is related to a specific issue within the business or residence. Sampling of water from the residence is done at the discretion of the attending staff member in order to eliminate the possibility that the suspected quality concern is related to the municipal supply.

SYSTEM IMPROVEMENTS
In 2020 the City invested approximately $1.3 million to replace small and medium diameter water mains aged or of poor condition. The City continued its practice of replacing old water services in conjunction with road paving projects.
SYSTEM MAINTENANCE
In 2020 the City of Coquitlam’s unidirectional flushing program continued, flushing the water systems in Noons Creek, Mountain, Summit, and Burnaby Mountain zones. Dead- end flushing occurred in the Burnaby Mountain, Foster, Westburnco, Brunette, Pipeline, Town Centre, River Springs, Abbey, Harper and Conifer zones.
The City continued with the tri-annual reservoir cleaning program in 2020 cleaning and disinfecting the Noons Creek, Summit and Mountain Reservoirs.

EXECUTIVE SUMMARY
Source Water Quality In 2020, the turbidity levels of the delivered water met the requirements of the Guidelines for Canadian Drinking Water Quality (GCDWQ). The Capilano supply was in service for the entire year. Heavy rainfall events in early January and late September resulted in Capilano source water turbidity peaking at 7.3 Nephelometric Turbidity Unit (NTU). Even with the higher turbidity, the delivered filtered Capilano water was less than 0.1 NTU as measured by online instruments for the entire year. The Seymour supply was in service for the entire year. Heavy rainfall events in January resulted in Seymour source water turbidity peaking at 23 NTU. The delivered filtered Seymour water was less than 0.1 NTU as measured by online instruments for the entire year. The Coquitlam supply was in service for the entire year. The unfiltered Coquitlam source water was greater than 1 NTU for 7 days in 2020 and did not exceed 5 NTU throughout the year. The microbiological quality of the three source waters was excellent in 2020. The levels of bacteria and protozoa detected were low and indicative of high quality source water. Coquitlam source water quality met the bacteriological requirements for avoiding filtration outlined in the turbidity section of the GCDWQ. Results of the analyses of the source water for herbicides, pesticides, volatile organic compounds and radionuclides were all found to be below the recommended limits for these substances as listed in the GCDWQ.
Water Treatment The Seymour Capilano Filtration Plant (SCFP) performance, as measured by the quality of the delivered water, was excellent in 2020. The daily average turbidity of water leaving the clearwells to enter the Greater Vancouver Water District (GVWD) transmission system was an average of 0.09 NTU in 2020. Turbidity levels for Individual Filter Effluent (IFE) met the turbidity requirements of the GCDWQ. Filtration consistently removed iron, colour and organics from the Capilano and Seymour source water. Levels of total aluminum in filtered water were consistently below the GCDWQ operational guideline value of 0.2 mg/L for direct filtration plants using aluminum-based coagulants. The maximum value for 2020 was 0.06 mg/L. There were no outages of ultraviolet treatment at the SCFP and the Coquitlam Water Treatment Plant (CWTP). The SCFP and CWTP operated the full year using sodium hypochlorite for chlorination. The secondary disinfection stations boosted chlorine when required.
Transmission/Distribution System Water Quality Bacteriological water quality was excellent in the GVWD transmission mains. No E. coli was detected. The detection of an E. coli triggers a protocol which involves immediate notification to health and local government officials, re-sampling, and a thorough investigation into the possible causes. Bacteriological water quality was excellent in the GVWD in-system storage reservoirs. There was no E. coli detected in any of the associated samples.
Greater Vancouver Water District 2020 Water Quality Annual Report | 1
Bacteriological water quality was excellent in the distribution systems of the local governments. Of approximately 20,000 local government samples collected for testing in 2020, a high percentage (99.8%) were free of total coliforms, which was the same as 2019 (99.8%). No E. coli were detected in any of the samples taken in 2020. The running average levels of the Trihalomethane (THM) group of chlorine disinfection by- products detected in the delivered water in the GVWD and local government systems were below the Maximum Acceptable Concentration (MAC) in the GCDWQ of 100 µg/L (0.1 mg/L). The running average levels for the Haloacetic Acid (HAA) group of chlorine disinfection by- products were below the GCDWQ Maximum Acceptable Concentration (MAC) of 80 µg/L (0.08 mg/L).

1.0 SOURCE WATER QUALITY The first barrier in place to protect the quality of drinking water supply is the protection of the watershed to ensure the best quality source water. Source water monitoring provides ongoing confirmation that the barrier is effective, identifies seasonal changes and provides the monitoring information necessary to adjust the level of water treatment that is in place. Regular monitoring of the water sources is also a requirement of the Water Quality Monitoring and Reporting Plan for Metro Vancouver (GVWD) and Local Government Members (WQMRP).
Greater Vancouver Water District 2020 Water Quality Annual Report | 4
1.1. Bacteriological Quality of the Source Water The bacteriological quality of the source water is an important indicator of the degree of contamination, and the treatment required to ensure a safe water supply. The Drinking Water Treatment Objectives (Microbiological) for Surface Water Supplies in British Columbia (DWTO) Section 4.3 states “The number of E. coli in raw water does not exceed 20/100 mL (or if E. coli data are not available less than 100/100 mL of total coliform) in at least 90% of the weekly samples from the previous six months. Treatment target for all water systems is to contain no detectable E. coli or fecal coliform per 100 ml.”
Table 1 summarizes E. coli data for all three GVWD water supply sources. The levels of E. coli for all three sources were below the 10% limit in the provincial turbidity guideline.
Table 1: Percent of Samples in Six Continual Months with E. coli/100 mL Exceeding 20 Percent of samples (daily) in a six month period ending on the last day of the month named where E. coli is greater than 20/100 mL Month Capilano Seymour Coquitlam Jan 2.2 3.3 1.1 Feb 2.8 3.4 1.1 Mar 0 0 0 Apr 0 0 0 May 0 0 0 Jun 0 0 0 Jul 0 0 0 Aug 0 0 0 Sep 3.3 3.8 3.3 Oct 4.3 8.7 3.8 Nov 4.4 8.8 3.9 Dec 4.3 9.2 3.3
Figure 1 shows the results of the analysis of the source water from 2016 to 2020 at all three intakes compared to the limits for source water bacterial levels in the DWTO. As in previous years, all three sources met the limit of not more than 10% exceeding 20 E.coli/100mL. As was also the case in previous years, samples collected at the intakes in the fall and winter had the highest E.coli levels. Typically, these E.coli can typically be traced back to high flow levels at the main tributaries of the supply lakes and a first flush phenomenon after a period of dry weather.

Note: Metro Vancouver has protected watersheds and therefore the source of E.coli is most likely originating from endemic animals in the watersheds.
1.2. Source Water Monitoring for Giardia and Cryptosporidium Unfiltered surface water supplies have the potential of containing the protozoan pathogens Giardia and Cryptosporidium. Outbreaks of Giardiasis occurred in a number of locations in B.C. and Washington State in the late 1980s, and Metro Vancouver has been monitoring raw water for Giardia since 1987. Since 1992, Metro Vancouver has participated in a program with the BC Centre of Disease Control Enhanced Water Testing Laboratory, to gather more information about the number and nature of cysts found in the GVWD water supplies. The program involves collecting samples from the Capilano and Coquitlam supplies upstream of disinfection.
At the SCFP, monitoring for Giardia and Cryptosporidium has focused on the recycled water returning to the head of the plant and this monitoring has confirmed that the procedures in place effectively control the levels of Giardia and Cryptosporidium in the recycled wash water from the filters.
The results of the 2020 testing program are contained in the “Report to Metro Vancouver – Giardia and Cryptosporidium Annual Report January – December, 2020”, which was prepared by the BC Public Health Microbiology & Reference Laboratories, Environmental Microbiology, and can be found in Appendix D. Four of twelve (33%) samples collected at Capilano and three of the twelve (25%) collected at Coquitlam were positive for Giardia (Table 2).
As discussed previously, Seymour samples for 2020 are all process control samples and not Seymour source water, as they were prior to 2011 (shown as N/A in the table).

Zero of twelve (0%) samples collected at Capilano were positive for Cryptosporidium, and 0 of twelve (0%) were positive at Coquitlam (Table 3). As discussed in the section on Giardia above, Seymour samples for 2020 are all process control samples and not Seymour source water, as they were prior to 2011 (shown as N/A in the table).
Table 3: Percent of Samples Positive of Cryptosporidium 2011 2012 2013 2014 2015 2016 2017 2018 2019 2020 Capilano 6 16 9 9 9 25 17 8 0 0 Seymour N/A N/A N/A N/A N/A N/A N/A NA NA NA Coquitlam 3 8 9 0 0 0 0 0 0 0
Year to year fluctuations are demonstrated for Giardia and Cryptosporidium and there has always been considerable variation in the results.
1.3. Turbidity GVWD water sources have been susceptible to turbidity upsets due to high runoff from storms which can cause slides and stream scouring in the watersheds, or from re-suspension of sediment from the edges of the lakes during periods of low water levels. The DWTO allows a utility to be exempt from filtration if the turbidity does not exceed specific water quality parameters requirements and provided that a number of other provisions, including source water protection and two forms of water treatment requirements, are in place. Historically the turbidity levels on both the Capilano and Seymour sources would not meet these criteria, therefore plans were developed and implemented to filter both supplies.
Filtration of 100% of the Seymour supply began in January 2010, and filtration and distribution of the Capilano supply through the Twin Tunnels connecting the Capilano and Seymour source supplies commenced in February 2015. Both the raw and treated water tunnels were fully operational in April 2015.
Section 4.4 of the DWTO (Version 1.1, November 2012) contains the following provision for filtration exemption:
“For nonfiltered surface water to be acceptable as a drinking water source supply, average daily turbidity levels should be established through sampling at equal intervals (at least every four hours) immediately before the disinfectant is applied. Turbidity levels of around 1.0 NTU but not exceeding 5.0 NTU for more than two days in a 12-month period should be demonstrated in the absence of filtration. In addition, source water turbidity also should not show evidence of harbouring microbiological contaminants in excess of the exemption criteria.”
Capilano and Seymour water is filtered so these source water criteria don’t apply to the delivered water. Coquitlam, which is unfiltered, was in service for all of 2020 in accordance with the DWTO.

1.4. Chemistry
1.4.1. Chemical and Physical Characteristics of Source Water The chemical and physical characteristics of the GVWD source water are summarized in Appendix A of this report; detailed analytical results are provided in Volume II. The results from the chemical and physical analyses of the source water in 2020 were similar to those for other years.
1.4.2. Herbicides, Pesticides, Volatile Organic Compounds, Radioactivity, and Uranium Analyses of the source water for a variety of organic compounds, including all of the compounds with an specified MAC in the Guidelines of Drinking Water Quality (GCDWQ), is carried out on an annual basis in accordance with the WQMRP. The results are contained in Appendix B of this report and in Volume II. Uranium was the only parameter detected and it was below the applicable GCDWQ health based limits; these levels are indicative of erosion of natural deposits, meaning the contribution to total radiation exposure from our drinking water is low.
1.4.3. PFOS and PFAS The GCDWQ have added the parameters of Perfluorooctane Sulfonate(PFOS) and Perfluorooactanoic Acid (PFAS) for testing of the source and treated waters. The results are in Appendix B of this report and in Volume II. None of the chemicals in these categories were detected. Common sources of these synthetic chemicals are from consumer products and fire-fighting foam for their water and oil repellant properties.
Greater Vancouver Water District 2020 Water Quality Annual Report | 8
1.4.4. Limnology The Reservoir Water Quality Monitoring Program was started in 2014 as a sampling and analysis structure for the limnology (physical, chemical, and biological parameters) of the Capilano, Seymour and Coquitlam Reservoirs. Reservoir monitoring information is important in the proactive management of the GVWD reservoirs, as water quality could be impacted by environmental variability and climate change. This program assists in ensuring that variation and trends in reservoir quality are scientifically tracked over time.
Water sampling of the primary source reservoirs and inflow rivers is conducted between April and November each year. Biological productivity that can influence water quality is the highest during this time of year, making it an important time for sampling and measurements. Monthly sampling of the source water is conducted by Metro Vancouver staff and sample analysis is undertaken by accredited laboratories. Water quality measurements are compiled by arrays of scientific instruments in each reservoir.
The GVWD employs the services of a limnology consultant to review the annual program data, interpret physical, chemical, and biological conditions and examine long term trends. Results in 2020, as in previous years, confirmed the three reservoirs are ultra-oligotrophic (see Appendix C), which means they have low levels of available nutrients and low levels of biological production. This ultra-oligotrophic classification is highly desirable for source drinking water supply and shows that the GVWD watersheds and reservoirs continue to provide a high quality raw water source.
In many parts of North America there is interest in blue green algae (also known as cyanobacteria) in water reservoirs. These algae can produce toxins that are collectively known as microcystins. A common cyanobacterium in GVWD source reservoirs is called Merismopedia spp., which is thought to produce these microcystins.
Despite the presence of cyanobacteria, the concentration of microcystins in GVWD source reservoirs remains well below levels known to affect human health and are far below the GCDWQ. This desirable condition is due to the ultra-oligotrophic status of the reservoirs (low nutrient availability to fuel algal growth). Algae blooms have not been observed in the source water supply reservoirs. Metro Vancouver continues to monitor cyanobacteria, including Merismopedia spp. as well as processes in the reservoirs that control the growth of cyanobacteria and other algae. This data is used to help predict changes to water quality over time related to climatic and environmental change and aid in making proactive decisions about ongoing reservoir management strategies.
Greater Vancouver Water District 2020 Water Quality Annual Report | 9
2.0 QUALITY CONTROL ASSESSMENT OF WATER TREATMENT Water treatment is the second barrier (after source water protection) relied on to assure the quality of the water supply.
Completion of the Twin Tunnels Project in 2015 successfully concluded GVWD’s regional long-range water treatment enhancement plans which spanned more than ten years. Each tunnel is 3.8 meters in diameter, 7.1 kilometers long, and 160 to 640 meters below ground level, running beneath Grouse Mountain and Mount Fromme. The water from the Raw Water Tunnel (RWT) is filtered and treated alongside the Seymour source water at the Seymour Capilano Filtration Plant (SCFP). Both treated sources enter the Clearwell at the SCFP for further treatment before the blended water is distributed to the region. Blended treated water returns to Capilano through the Treated Water Tunnel (TWT) and provides high quality drinking water to the Capilano area while the remainder is distributed through the Seymour system.
2.1. Seymour Capilano Filtration Plant The SCFP is a chemically assisted direct filtration plant which uses poly aluminum chloride as a coagulant with polymers to improve particle removal. These substances help aggregate particles to form visible floc. The flocculated particles are removed by passing this water through a filter medium of anthracite and sand. The result is the production of filtered water which is then exposed to ultraviolet light as the water leaves each filter. Post ultraviolet filtered water has sodium hypochlorite (chlorine) and lime added before the water enters the Clearwells. The West and East Clearwells are large water storage reservoirs that store and allow controlled passage of water with some mixing (or blending) of the lime and chlorine that have been added. Clearwells allow sufficient retention (or contact time) with chlorine to provide any further disinfection required after filtration and ultraviolet light treatment. Carbon dioxide (CO2) in solution is added to trim pH once the desired alkalinity is reached. After stabilization of the filtered water in the Clearwells, the finished water enters the transmission system at the Seymour Treated Water Valve Chamber. The SCFP has been operational since January 2010 and the quality of the water produced has been excellent.
2.1.1. Filtration As a result of filtration treatment of the Capilano and Seymour water sources, there have been a number of changes to the characteristics of the delivered water. Some of these changes are visible, and some are not. The most obvious visible change in the water is the decrease in colour and increase in clarity. There is a total loss of brown hue that can sometimes characterize Capilano and Seymour waters before filtration. This improvement in colour is a result of removal of the natural components that cause the brown hue by the filtration process. Suspended particles in water that cause light to scatter (turbidity) are also removed. The end product is water that is very clear. Due to the purity of the water, it may have a slight bluish tinge.
Figure 3 compares the apparent colour of SCFP filtered water and Capilano and Seymour source waters for 2020. During the fall rainfall events, the apparent colour of the Seymour source water feeding the SCFP had a reading over 50 ACU. After the removal of the organic material through filtration, the colour of the filtered water delivered to the public was never greater than 2 ACU.

Figure 4 compares turbidity of the two source waters that feed the SCFP to the turbidity level of the finished water. The Seymour source experienced an average daily turbidity greater than 1 NTU for 116 days. The Capilano source exceeded 1 NTU on 114 days. Since both sources were filtered at the SCFP, the maximum average daily turbidity of the delivered water was 0.19 NTU and the average was 0.09 NTU.

Removal of turbidity in the source water improves the aesthetic qualities of the water, but it also has the benefit of removing certain types of pathogenic microorganisms that may be present. At a minimum, properly run direct filtration plants such as the SCFP will remove up to 2.5 log (two log is a 99% reduction) of Giardia and Cryptosporidium plus 1 log of viruses. To ensure this removal, it is critical that the performance of each filter determined by the turbidity of its effluent is monitored on a continuous basis.
The GCDWQ (2019) states: “For conventional and direct filtration, less than or equal to 0.3 nephelometric turbidity units (NTU) in at least 95% of measurements either per filter cycle or per month and never to exceed 1.0 NTU.”
Ideally the turbidity from each filter would never exceed 0.1 NTU; however, there are rare occurrences of turbidity readings that exceed this ideal level. The turbidity performance of all 24 filters is measured by examining the percent of time that the turbidity of each Individual Filter Effluent (IFE) met the turbidity guidelines of not greater than 1.0 NTU and at least 95% of time less than 0.3 NTU. This is summarized in Table 4. In 2020, there were no incidents where the IFE was greater than 1.0 NTU and the few incidences of filter turbidity readings that were greater than 0.3 NTU, were well within the 95% limit.
Greater Vancouver Water District 2020 Water Quality Annual Report | 12

A water treatment facility such as the SCFP should be able to produce a filter effluent that is less than 0.1 NTU. Under normal operating conditions the turbidity of the filtered water at SCFP is less than 0.09 NTU.
All water that flows through the filters immediately passes through the ultraviolet units. The intensity of the ultraviolet lamps automatically increases when there is an increase in turbidity of the water exiting each filter. After ultraviolet treatment, the water is chlorinated as it enters the clearwell, where more than one hour of contact time is provided.
2.1.2. Ultraviolet Treatment The effluent from each filter is treated with ultraviolet light as the water exits the filter. Ultraviolet treatment is effective in altering the DNA structure of Giardia and Cryptosporidium. thus rendering cysts and oocysts, respectively, of these parasites non-infectious. Other disinfectants, especially chlorine, are ineffective against Cryptosporidium oocysts at reasonable dosages. In the unlikely event of a breakthrough of Cryptosporidium oocysts, especially at the end of a filter run, ultraviolet light is present to render any parasites that may be present as non-infectious. Oocysts are not able to proliferate inside the intestines of human hosts to cause illness after a sufficient dose of ultraviolet light. The target dosage for ultraviolet light is to achieve 2-Log (99%) Giardia and Cryptosporidium inactivation is 21 mJ/cm2.
Under normal operating conditions, two rows of lamps operating at 75% power provide sufficient ultraviolet light to meet the dosage requirement for 2-log reduction of Giardia and Cryptosporidium
Table 5 summarizes the performance of the SCFP ultraviolet system in 2020.

2.1.3. Chlorination Chlorination is used for secondary disinfection at the source as well as at secondary disinfection stations to minimize bacterial regrowth in the GVWD transmission and local government distribution systems. Chlorination provides 4-log virus inactivation with liquid sodium hypochlorite.
2.2. Coquitlam Water Treatment Plant The Coquitlam Water Treatment Plant (CWTP) uses ozonation, ultraviolet treatment, soda ash and chlorination to treat water from the Coquitlam source.
Ozonation provides pre-treatment and helps remove micro-organisms from the water, reduces disinfection by-products and improves water clarity, which increases the efficiency of the subsequent ultraviolet process. Ozonation provides an additional 4-log virus inactivation to chlorination. Soda ash is then added for pH and alkalinity adjustment for corrosion control, followed by chlorination.
2.2.1. Ultraviolet Treatment Ultraviolet treatment (operational since 2014) provides for primary disinfection, and achieves 3-log inactivation of chlorine-resistant micro-organisms for Giardia and Cryptosporidium. The water is directed into 8 ultraviolet units, each containing 40 ultraviolet lamps encased in protective sleeves. Ultraviolet light emitted from the lamps passes through the water. The US Environmental Protection Agency (USEPA) requires that the ultraviolet disinfection process results in target Giardia and Cryptosporidium inactivation in at least 95% of the treated water volume on a monthly basis, which is summarized in Table 6. The USEPA standard is used because there is no Canadian standard.

2.2.2. Chlorination Chlorination is used for secondary disinfection at the source as well as at secondary disinfection stations to minimize bacterial regrowth in the GVWD transmission and local government distribution systems. Chlorination provides 4-log virus inactivation with liquid sodium hypochlorite, which replaced the compressed chlorine gas system in 2017. Table 7 summarizes the performance of all the Coquitlam disinfection systems in 2020.

Chlorination 100% of water was chlorinated This facility uses chlorine as a secondary disinfectant except during an outage of the ultraviolet system when it is used for primary disinfection.
Greater Vancouver Water District 2020 Water Quality Annual Report | 16
2.3. Secondary Disinfection There are 8 secondary disinfection stations operated by Metro Vancouver. The purpose of these stations is to increase the chlorine residual in the water transmission and distribution systems to meet a target residual based on a number of factors, including source water turbidity, the amount of bacterial regrowth detected in the local government distribution system samples and the chlorine demand in the water. The rate of chlorine decay is lower in the areas receiving filtered water from the SCFP and consequently, lower chlorine dosage levels are required to maintain desired chlorine residual levels. The target chlorine dose leaving the secondary facilities receiving SCFP water is 0.8 mg/L. These facilities frequently have an incoming chlorine residual high enough that boosting is not required. The target chlorine dose leaving the secondary facilities receiving CWTP water ranges from 1.20 to 1.50 mg/L.
Table 8 summarizes the performance of the secondary disinfection facilities in 2020.

2.4. Corrosion Control Metro Vancouver’s Corrosion Control Program began in the 1990s and involves several steps to reduce pipe corrosion. As part of the current Corrosion Control Program: Copper Pipes Protection initiative, further proposed changes in pH and alkalinity in 2021 will reduce pipe corrosion through the addition of natural minerals.
The untreated water from all three sources had a pH lower than the aesthetic limit of the GCDWQ of pH 7.0.
In the SCFP process, filtered water is dosed with hydrated lime (calcium bicarbonate) to raise its pH and alkalinity before it enters the clearwells. To achieve the desired alkalinity, the resultant pH is trimmed using CO2 to bring it down to target levels. Since 2015, by way of the Twin Tunnels, Capilano raw source water is transferred to the SCFP for treatment.
At the Coquitlam source, the commissioning of the CO2 system at the CWTP began in 2019 and continued in 2020. When it is fully operational, the CO2 system with the addition of soda ash will allow the GVWD to meet new target pH and alkalinity values across the entire system. Similar to the SCFP, the CO2 system is used to trim the resultant pH to desired target levels.
The average pH of the treated water leaving Seymour Capilano and Coquitlam Water Treatment Plants was 7.7 and 7.8, respectively, during 2020, which met the aesthetic objective of the GCDWQ.
Performance of the corrosion control facilities is summarized in Table 9. Table 9: Performance of Corrosion Control Facilities Facility Performance Discussion SCFP Corrosion Control pH ranged from 6.9 – 9.0 The annual average pH was 7.7 and was continually monitored with online instrumentation.
The pH fluctuated in March from 6.9 to 9. During this time one clearwell was being bypassed for maintenance resulting in pH fluctuations while bringing this clearwell back into service.
CWTP Corrosion Control pH ranged from 6.8 – 9.6 The annual average pH was 7.8.
On a couple of occasions in January the pH was <7.0 for a short period due to a soda ash equipment fault.
In January and also in June the pH was > 9 for a short period related to testing of the soda ash system.
The chemical and physical characteristics of the GVWD treated water are summarized in Appendix A of this report and detailed analytical results are provided in Volume II.

3.0 TRANSMISSION/DISTRIBUTION SYSTEM WATER QUALITY Schedule A of the BC Drinking Water Protection Regulation (BCDWPR) contains standards for the bacteriological quality of potable water in the Province. There are three components of this standard that apply to large utilities such as GVWD and its members. These are:
Part 1: No sample should be positive for E. coli.
Part 2: Not more than 10% of the samples in a 30-day period should be positive for total coliform bacteria when more than 1 sample is collected.
Part 3: No sample should contain more than 10 total coliform bacteria per 100 mL.
The BCDWPR does not contain any water standards other than the three limits for E. coli and total coliform bacteria. Information on the significance of the detection of these organisms can be found in the GCDWQ – Supporting Documents, specifically:
“E. coli is a member of the total coliform group of bacteria and is the only member that is found exclusively in the faeces of humans and other animals. Its presence in water indicates not only recent faecal contamination of the water but also the possible presence of intestinal disease-causing bacteria, viruses and protozoa.”
“The presence of total coliform bacteria in water in the distribution system (but not in water leaving the treatment plant) indicates that the distribution system may be vulnerable to contamination or may simply be experiencing bacterial regrowth.”
To summarize, the detection of an E. coli bacteria in a sample of treated water is an indication of a potentially serious risk. The detection of total coliform bacteria may indicate intrusion into the system, or it may indicate that these bacteria are growing in the distribution system itself (regrowth).
The number of E. coli detected in both the GVWD and the local government drinking water samples is typically very low. Out of more than 27,000 samples collected from the GVWD and local government systems analyzed in 2020, no samples were positive for E. coli. The detection of an E. coli triggers a protocol which involves immediate notification to health and local government officials, re-sampling, and a thorough investigation into the possible causes.
In the GVWD transmission system, only 27 out of the approximately 7,100 samples collected, tested positive for total coliforms. Only 38 of the approximately 20,000 samples collected from the local government distribution systems tested positive for total coliforms in 2020. The majority of the coliforms (67%) in the local government system appeared in the warmer water months of June through October.
The most likely source of these organisms can be attributed to bacterial regrowth. It should be emphasized that 99.8% of the samples in 2020 had no coliforms present, which is a good indicator of effective water treatment and good transmission/distribution system water quality.

3.1. Microbiological Water Quality in the GVWD System
3.1.1. GVWD Water Mains Water quality in water mains is monitored from the point leaving the source and throughout the transmission system. In 2020 there were approximately 5,080 samples collected and tested for the presence of indicator bacteria. The percentage of samples from the GVWD water mains that were positive for total coliform bacteria was very low, well below the 10% standard. Of the approximately 5080 samples processed, only 21 samples tested positive for total coliforms and no samples were positive for E. coli bacteria. The compliance of monitoring results from GVWD transmission mains with the criteria in the BCDWPR is shown in Figure 5.
There were another 540 samples collected from stations where only chlorine residuals are measured. In addition, there are inline stations collecting data every 10-minutes after chlorination at each source, but these samples are not included in the calculations for compliance monitoring.

Reservoir water quality is optimized by the use of secondary disinfection coupled with an active reservoir exercising program that includes a minimum of weekly monitoring of chlorine residuals and bacteriology results, which can result in changes to filling levels, if necessary.
Table 10 provides an overview of the status of the GVWD reservoirs from 2017 to 2020. During certain times of the year, it is not possible to cycle reservoirs as much as would be desired due to operational constraints. Despite these constraints, water quality as determined by coliform bacteria, was satisfactory in all reservoirs.

The percentage of samples positive for total coliform bacteria in 2020 remained relatively similar as compared to 2019.
Schedule A of the BCDWPR contains standards for the bacteriological quality of potable water in the Province. There are three components of this standard that apply to local governments:
Part 1: No sample should be positive for E. coli.
Part 2: Not more than 10% of the samples in a 30-day period should be positive for total coliform bacteria when more than 1 sample is collected.
Part 3: No sample should contain more than 10 total coliform bacteria per 100 mL.
Greater Vancouver Water District 2020 Water Quality Annual Report | 24
For samples from local government systems, this requirement was met in 2020 with the following exceptions: Two samples in June contained more than 10 total coliform bacteria. Three samples in September contained more than 10 total coliform bacteria. Two samples in October contained more than 10 total coliform bacteria.
Table 11 shows the compliance with the bacteriological standards (3 parts) in the BCDWPR for samples taken within the distribution systems of the 20 local governments that are supplied with GVWD water.

3.3. Disinfection By-Products in the Transmission/Distribution Systems As the treated water moves through the GVWD Transmission system and into the local government distribution system infrastructure of pipes and reservoirs. Changes in water quality occur mainly due to the reaction between the chlorine in the water (added during primary and secondary disinfection) and naturally occurring organic matter in the water.
One of the most significant changes is the production of chlorinated disinfection by-products (DBPs). DBPs is a term used to describe a group of organic and inorganic compounds formed during water disinfection.
Reactions between dissolved natural organic matter and chlorine can lead to the formation of a variety of halogenated DBPs. There are two major groups of chlorinated DBPs: The Total Trihalomethanes (TTHMs) and the Total Haloacetic Acids (THAA5). Factors that affect DBP formation include: amount of chlorine added to water, reaction time, concentration and characteristics of dissolved organic materials (precursors), water temperature, and water pH. In general, DBPs continue to form as long as chlorine and reactive DBP precursors are present in water.
The Maximum Acceptable Concentration (MAC) in the GCDWQ for TTHMs is a locational yearly running average of 100 µg/L (0.1 mg/L) based on quarterly samples. A comparison of TTHM levels in the GVWD and local government systems in 2020 is shown in Figure 8. All THM results from GVWD water mains and local government systems were below the MAC of 100 µg/L.

Figure 8: Average Total Trihalomethane Levels
2020 Average GVWD TTHM = 22 µg/L 2020 Average Local Governments TTHM = 31 µg/L
The other group of disinfection by-products of interest is the Total Haloacetic Acid (THAA5) group. Comparison of THAA5 in the GVWD and local government systems in 2020 is shown in Figure 9. In 2020, eight locations had a single quarterly sample with THAA5 readings above 80 µg/L. The MAC is calculated on a locational yearly running average based on quarterly samples and despite the higher single readings, no location exceeded the yearly 80 µg/L MAC.

4.0 QUALITY CONTROL/QUALITY ASSURANCE In 1994, as required by a new BC Ministry of Health program, the bacteriology section of the GVWD Laboratory received approval from the Provincial Medical Health Officer to perform bacteriological analysis of potable water as required in the BCDWPR. An ongoing requirement of this approval is successful participation in the provincial Clinical Microbiology Proficiency Testing Program or its equivalent. Representatives of the Approval Committee for Bacteriology Laboratories have carried out an inspection of the GVWD Laboratory facilities at the Lake City Operations Centre in February 2019 as part of the process leading up to approval of the laboratory by the Provincial Health Officer. The next inspection is scheduled for 2022.
In addition to the approval process discussed above, the GVWD Laboratory is accredited by the Canadian Association for Laboratory Accreditation (CALA) for the analysis of parameters for which the laboratory
Greater Vancouver Water District 2020 Water Quality Annual Report | 27
has requested certification. The GVWD Laboratory has been inspected by representatives from CALA bi- annually since 1995.
Accreditation for the laboratory from the Standards Council of Canada was first received early in 1996 and continued until the middle of 2005, when accreditation was granted by CALA directly.
The most recent on-site audit took place in November 2019, and CALA issued accreditation approval in February 2020. The next CALA inspection will take place in the fall of 2021.

Where the range is a single value no variation was measured for the samples analyzed. Average values containing one or more results below the detection limit are preceded with “<” symbol. Minimum range values than “<” denotes not detectable with the technique used for determination. Methods and terms are based on those of the most current on-line version of "Standard Methods for the Examination of Water and Waste Water". Untreated water is from the intake prior to treatment, treated water is from a single site in the GVWD distribution system downstream of CWTP. Guidelines are taken from the most current Guidelines for Canadian Drinking Water Quality summary table updated in September 2020. Recommended turbidity guidelines applies to finished treated water from an un-filtered source. Coquitlam source was operational for 365 days in 2020.

Academic Press. New York. Ultraoligotrophic means very low nutrient content and very low biological production: very high water quality Oligotrophic means low nutrient content and low biological production (low risk of algal blooms): high water quality 2Chemical measurements are defined as follows: Phosphorus and nitrogen are nutrients that primarily control the growth of algae, including cyanobacteria. Phytoplankton biomass includes cells of all algae and cyanobacteria species in a reservoir. 3Values are averages from all water depths during April through November of all years. Values in brackets are average values only from 2020.
