EXECUTIVE SUMMARY

Under the Province of British Columbia’s Drinking Water Protection Act and the Drinking Water Protection Regulation, the City of Castlegar is mandated to continually monitor drinking water quality and to make available to the public an annual water quality report. The Annual Water Quality Report is meant to provide water users with information about their drinking water’s quality based on ongoing monitoring. The annual reporting is also required under the City’s municipal water system operating permit, issued by the BC Interior Health Authority (IHA). This report summarizes the results of drinking water quality monitoring and operations in Castlegar in the year 2017.

· Universal Water Metering program continues, and the City is transitioning all customers to a volumetric-based utility billing system in 2017. (Paying for how much water you use.) · The Drinking Water Protection Act of BC requires that a water-source assessment be completed by each Water Utility. The City is continuing to implement the recommendations contained in the 2014 Arrow Reservoir Source Assessment. · Water samples are tested to meet the Objectives for Drinking Water Quality and the requirements for ongoing “exclusion of filtration”. Forty-nine raw water samples were taken in 2017, and were tested by an independent laboratory for bacteria. · In 2017, the raw water samples met the criteria for E.coli and fecal coliform bacteria and the sampling site was repositioned in order to meet the criteria for total coliforms which was showing some false-positive results. · The bacteriological quality of water distributed in 2017 was in full compliance with all regulations. · In 2017, the City’s water system met all regulatory requirements for drinking water quality as set out by the BC Drinking Water Protection Act. · No treated water samples tested positive for E. coli in 2017. And 100% of the treated samples had no Fecal and no Total Coliforms per 100 mL. · Average total Trihalomethane results were well below the Health Canada guideline of 100 ppb. · The City of Castlegar has experienced gradually increasing algae levels over the past few years. In 2017, an algae issue was noted as a concern and was addressed through the flushing program. · The raw water from the Arrow Lakes reservoir is treated by the City of Castlegar using ultraviolet (UV) irradiation (Primary Disinfectant) to inactivate protozoa, and using chlorine gas (Secondary Disinfectant) to inactivate viruses. Additional chlorine is added to the water as a “residual” disinfectant. · The UV disinfection system provides the residents of Castlegar with a reliable disinfection barrier to ensure consistently safe drinking water. · Some turbidity (cloudy water) was experienced by customers in 2017; however, this was usually caused by normal operation & maintenance activities, such as flushing. · In 2017, the City of Castlegar staff focused their flushing efforts on the North end of the City (to Twin Rivers area). The City continues to improve and advance their “Uni-Directional Flushing Program” each year. · In 2017 the City expended just under $948,000 for Capital Works on the City’s water treatment center and the water distribution system.

The City of Castlegar is committed to providing clean, safe drinking water through the responsible management and maintenance of local water infrastructure. This report has been submitted to the Interior Health Authority and will be posted on the City of Castlegar’s website once it has been endorsed by Castlegar City Council.

2017 ANNUAL WATER QUALITY REPORT WSP Project No. WSP NO. 181-09051-00 CITY OF CASTLEGAR Page 2

1 INTRODUCTION The City of Castlegar (population 8,992) is situated at the confluence of the Kootenay and Columbia Rivers in the southwestern corner of the Kootenays within the Regional District of Central Kootenay. The City’s primary water source is the Lower Arrow Lakes reservoir. The City of Castlegar water utility partners with the Zellstoff-Celgar pulp mill to provide potable water from an intake in Lower Arrow Lake and provides potable water to approximately 2,703 residential customers and 300 institutional/commercial connections. The Lucas Road Water System is serviced with bulk treated water from the City of Castlegar.

1.1 REGULATING AUTHORITIES The City of Castlegar is required by the BC Interior Health Authority (IHA) to contract a private laboratory, each month, to perform testing of total coliform and fecal coliform counts on water samples from five locations within the distribution system. These tests are representative of potential bacterial contamination in the water. Data results are entered into WaterTrax, a computer database that simultaneously alerts public health authorities, water operations staff, and management, if microbiological parameters exceed the Guidelines for Canadian Drinking Water Quality. The City holds a water license (No.C053338) on Lower Arrow Lake for waterworks dated October 20, 1978. The City is licensed to divert 10,786ML annually. The actual demand by the City has been substantially less than the available licensed volume. In 2015 demand was 3.15 ML for the year; and in 2017 the total water production was 3.20 ML. The City of Castlegar holds a permit to operate its Water Treatment Centre (Class II Facility #2239) and its distribution system (Class III System #125) from the IHA and adheres to the provisions of the Local Government Act.

Water quality requirements are legislated by the Drinking Water Protection Act and the Drinking Water Protection Regulation of BC

The water distribution system has been classified by the Environmental Operators Certification Program (EOCP) as a Class III System. In 2017, the City of Castlegar’s water utility was maintained by EOCP certified operators, as required.

1.2 DRINKING WATER OBJECTIVES The Guidelines for Canadian Drinking Water Quality (GCDWQ) are established by the Federal-Provincial- Territorial Drinking Water Committee to outline the Maximum Acceptable Concentrations of drinking water contaminants. These guidelines, published by Health Canada, are used to assess the safety of drinking water and to help determine treatment needs. The GCDWQ are broken into three parts: microbiological parameters; chemical/physical parameters; and radiological parameters.

INTERIOR HEALTH AUTHORITY 4-3-2-1-0 DRINKING WATER OBJECTIVE

4 log inactivation of viruses (this means 99.99% removal);

3 log removal or inactivation of protozoa (Giardia Lamblia and Cryptosporidium Parvum) (this means 99.9% removal);

2 treatment barriers, (duel treatment for all surface water or unprotected groundwater);

1 NTU, maintaining turbidity levels of less than 1.0 NTU; and,

0 indicators of bacterial contamination (either Fecal Coliform or E.Coli bacteria).

The IHA summarizes the objectives as the 4-3-2-1-0 method1 (outlined above). Water suppliers are required to provide potable water to all users on their systems.

1 Interior Health – Health Protection – Drinking Water Program Brochure No. HPF9040, published January 2006. The 4-3-2-1-0 drinking water objective provides a performance target for water suppliers, to ensure the provision of microbiological safe drinking water. IHA supports water suppliers to meet this objective. All water suppliers serving populations greater than 50 people should meet this as a standard.

2 WATER CONSUMPTION

2.1 WATER DEMAND IN 2017 Water demand in the City of Castlegar is generally influenced by weather. Hotter, drier weather typically drives higher demand, while cooler, wetter summers will tend to result in lower demand, for both peak- daily and total annual demand. Hot and dry springs and summers have a dramatic influence on the volume of potable water consumed, as seen in 2015 and again in 2017 (see Table 1, and Figure 1). Over the years the water demand in Castlegar has gradually increased, and is still showing a rising trend in 2017.

Below is a graph showing the 2016 and 2017 consumption for the City of Castlegar Water Utility. There are large shifts in consumption seasonally, due to water/irrigation demands during the summer months. Peak season water demand can increase by as much as 30% (see Figure 2) over the average monthly demand.

2.2 UNIVERSAL WATER METERING The City of Castlegar has been implementing a Universal Water Metering program as a method of addressing excessive water usage and promoting water conservation since 2009. This program is a key component in demand-management. In 2016, the City, completed their Water-Smart Action Plan 2015-2020. “In 2013, the City installed new source water meters which measure more accurately than the older instrumentation. Therefore, comparisons with prior years’ water demand should not be made. The City should establish a new baseline year of 2014 to accurately assess change in demand year over year. Water demand in Castlegar is well above the provincial average… suggesting that there continue to be cost effective opportunities to reduce total and peak water consumption in the City”. Section 5 of the Water Smart Action Plan details several actions that the City can take to further their water conservation efforts2. The City of Castlegar has installed more than 2,500 water meters or 90% of residential service connections. All commercial service connections (over 300 connections) are now metered. In 2017, the City is completing the process to transition all customers to a volumetric based utility billing system (during 2017 to 2018). A record of household water consumption is available to customers on the City’s website, providing residents with information related to their water use compared to the community wide average.

3 SOURCE WATER QUALITY

3.1 RAW WATER INTAKE The City of Castlegar’s water intake is located on the west shore of the reservoir, off Arrow Lakes Drive, immediately upstream of the Hugh Keenleyside Dam (owned and operated by BC Hydro). The dam (1968) created a single large reservoir from what were formerly known as Upper and Lower Arrow Lakes, part of the Columbia River system. The minimum reservoir level is specified in the Columbia River Treaty (as 417.00 m ASL). According to the Arrow Reservoir Source Assessment report3, the Castlegar water intake “is set at an elevation of 405.4 m [and] is a submerged screened pipe in the reservoir… at an average depth of 26.5m. The intake is shared with Zellstoff Celgar” property. Water supply is not a significant issue for the City as the amount of storage in the reservoir/lake and the operational components of the Columbia River, provide robust supplies4. The Arrow Lakes reservoir has historically provided very high-quality drinking water to the City. The source area upstream of the City intake is the Columbia River watershed that is approximately 36,500 square kilometers. From the pump house at the intake, water is piped to the City of Castlegar’s Water Treatment Centre (WTC) where water is treated, tested and monitored for quality before being directed throughout the distribution system.

3.2 RAW WATER OBJECTIVES The 2003 Drinking Water Protection Act of BC (DWPA) enables provincial enforcement of the GCDWQ. Section 18 of the DWPA requires a water-source assessment be completed. A Drinking Water Source-to-Tap Assessment Guideline was released by the SOURCE-TO-TAP Ministry of Health in 2010. The primary aim of this assessment is ASSESSMENT to identify hazards and vulnerabilities that may threaten the safety CATEGORIES and sustainability of the water supply throughout the system. The Action Plan for Safe Drinking Water in BC recognizes source The drinking water protection as a critical part of drinking water protection. multiple source-to-tap barrier assessment comprises of analysing the Surface water sources – lakes, streams, creeks, rivers and precipitation, are open to the atmosphere, making these following six steps: sources particularly vulnerable to contamination by the actions of humans or animals or by natural events in the watershed such as landslides, fires or extreme runoff from 1) Source heavy rain.

3.3 RAW WATER QUALITY MONITORING

3.3.1 BACTERIOLOGICAL TESTING IN 2017 The City of Castlegar performs weekly bacteriological testing for Escherichia-coli (E.coli) and total coliform bacteria throughout the distribution system. The first sampling location is at the Water Treatment Centre (WTC), testing the raw water when it first arrives. This regular weekly testing monitors microbiological threats, which might be present in the source water from Arrow Lake (reservoir). Water samples are tested to meet the requirements for drinking water and exclusion of filtration. Forty-nine (49) bacteriological raw water samples were taken in 2017, and were tested by an independent laboratory. In 2017, the raw water met the criteria for E.coli, (only 1 weekly sample in 24 total samples taken in the previous six months, exceeded the limit of “20/100mL” in 2017. This amounts to 98% of samples meeting the criteria for E.coli. Although the E.coli criteria was achieved, the total coliform results did not always appear to meet the guideline of “less than 100/100mL in at least 90% of the weekly samples”. In the first half of 2017, the water samples were meeting the criteria for total coliforms; however, in the second half of 2017, 4-of-24 weekly samples had greater than 100/100mL total coliforms (16% had greater than 100 units of total coliforms per 100mL). This change in test results coincides with a relocation of the raw water sampling site, which occurred in late 2017. The new location seemed to be resulting in some false positives. The City of Castlegar staff investigated this matter, reconfigured the testing location and has since reduced the raw water total coliform counts to within the required criteria.

3.3.2 TURBIDITY MONITORING IN 2017 Turbidity is a measure of water clarity. It is measured in NTU’s (nephelometric turbidity units) and describes the percentage of light which is scattered and absorbed, versus being transmitted through the water. Turbidity is a crucial measurement as part of the drinking water monitoring process because extra sediment/silt/organic matter in the water can cover or hide bacteria, thus reducing the effectiveness of the disinfection process (especially using UV light treatment). It is noted that turbidity, total-suspended-solids (TSS), total-dissolved-solids (TDS), and UV-transmittance results vary at different times of the year. The IHA criteria for filtration exclusion requires that “the average daily turbidity levels measured at equal intervals (at least every four hours) immediately before the disinfectant is applied are around 1 NTU, but do not exceed 5 NTU for more than two days in a 12-month period.” Average monthly turbidity is shown in Figure 4, and was generated based on daily monitoring results throughout 2017. Turbidity is also monitored by the automatic SCADA sensor system (alarmed). See Appendix B for complete set of monitoring data and laboratory test results.

3.3.3 FULL CHEMICAL ANALYSIS TESTING City staff collect quarterly raw water samples at the WTC and submit it to the professional laboratory for a full chemical analysis. When a full chemical analysis is completed on the source water, it is testing for many additional constituents such as: alkalinity; hardness; conductivity; pH; fluoride; arsenic; lead;

2017 ANNUAL WATER QUALITY REPORT WSP Project No. WSP NO. 181-09051-00 CITY OF CASTLEGAR Page 9

mercury; and other chemicals and metals. Figure 5 shows the pH levels measured in 2017; however, pH is not a property which can be adjusted by the City. Alkalinity and hardness levels are generally low for this source5; pH levels range from about 7.7 at the surface to 7.0 at a 30m depth in the reservoir.

3.3.4 ALGAE BLOOMS AND NUTRIENTS IN 2017 Algae is a broad term including organisms of widely varying sizes, growth rates and nutrient requirements. There is no officially recognized threshold level as to what is defined as an algae bloom. Freshwater algae blooms are the result of an excess of nutrients, particularly some phosphates. These excess nutrients may originate from fertilizers that are applied to land for agricultural purposes, or nutrients being added to the lake water for recreational (fish stocking) purposes. They may also originate from household cleaning products containing phosphorus. These nutrients can enter watersheds through water runoff. Occasional algae blooms have been identified as a potential drinking water hazard in water intake systems, resulting in clogging of the lines, some poor odour/taste, and increases in THM (trihalomethane) concentrations. The City of Castlegar has experienced gradually increasing algae levels over the past few years. In 2017, an algae issue was noted as a concern and was addressed locally through the flushing program of the distribution system. Algae was more of a problem closer to the source intake end of the system than at the far end of the distribution system, and tended to settle out near the beginning of the system. Ultimately, the incidence of algae blooms will continue if the source water remains rich in nutrients. The upstream reservoir waters continue to be enriched with nutrients by the Provincial Government, to increase recreational fish stocks.

3.4 SOURCE ASSESSMENT REPORT Another exclusion of filtration criteria for the source water is the maintenance of a watershed protection program that minimizes the potential for contamination of the source water. In 2014, the City of Castlegar commissioned the preparation of the Arrow Reservoir Source Assessment6 report. The intent of the source assessment was to identify existing or potential hazards to the source water at the City’s intake and to make recommendations to reduce those threats or risks in the future. Section 6 recommendations for the City has been included as Appendix D. The City is continuing to work on implementing the recommendations contained in the Arrow Reservoir Source Assessment, as required by the conditions of IHA. However, due to the size of the Arrow Lakes reservoir and Columbia River watershed, implementing all the recommendations in the report would require substantial input and cooperation from many different organizations, governing bodies, and stakeholders, including senior government. The City of Castlegar is not currently kept appraised of the status of the Provincial (Forests, Lands, Natural Resource Operations & Rural Development ministry) nutrient program in the lake water. A formal water quality monitoring program was completed by the City in 2016 and was approved by IHA.

4 WATER TREATMENT PROCESS The treatment target for all water systems is to contain no detectable E. coli or fecal coliforms per 100mL. Total coliform objectives are also zero based on one sample in a 30-day period. For more than one sample in a 30-day period, at least 90% of the samples should have no detectable total coliform bacteria per 100mL and no sample should have more than 10 total coliform bacteria per 100mL. The City of Castlegar’s water system met these targets in 2017. No E. coli or Fecal Coliforms were detected in any of the treated water samples. Over 95% of samples tested had less than one count per 100mL of total coliforms. And the other 5% contained only 1/100mL, which may have been either a human sampling error or a laboratory error.

4.1 PRIMARY TREATMENT AND DISINFECTION The water diverted from the Arrow Lakes reservoir is treated by disinfection for the City of Castlegar. The disinfection process uses ultraviolet (UV) irradiation (Primary Disinfectant) to inactivate protozoa and chlorine gas (Secondary Disinfectant) to inactivate viruses. Then additional chlorine is added to the water, as a residual disinfectant prior to distribution. In August 2013 the City installed the Trojan-Ultra-Violet system (UV disinfection). The UV disinfection system provides the residents of Castlegar with a reliable disinfection barrier to ensure consistently safe drinking water. The City’s system achieves the requirement that “overall inactivation must be met using a minimum of two disinfections, providing 4-log reduction of viruses and 3-log reduction of Cryptosporidium and Giardia”. The UV system is designed to maintain a minimum a dose of 12.2 mJ/cm2 in order to provide the required 3_log (99.9%) inactivation of protozoa. The chlorination system is intended as the secondary disinfectant to provide 4_log (99.99%) inactivation of viruses.

4.2 CHLORINE RESIDUAL The free chlorine residual is extremely important to ensure potable (safe for drinking) water is delivered to the residents of the City of Castlegar. The rate of chlorine injection can vary throughout the year depending largely on source water temperature and organic concentrations. In 2017, the City maintained the provincial health standard of a minimum free chlorine residual of 0.20mg/L at the outermost areas of the water distribution system. Rate of injection at the WTC can vary from 0.75mg/L to 1.00mg/L, to achieve that free chlorine residual of 0.20mg/L. The City regularly measures residual chlorine at six locations throughout the distribution system (see Figure 6) and monitors minimum residual chlorine concentrations.

5 DISTRIBUTION SYSTEM Treated drinking water is then directed to eight reservoirs, five pump-stations, and thirteen pressure- reducing valve stations (PRVs), throughout the City of Castlegar7. The total available reservoir storage capacity is 11.5 Megaliters. The City’s 109 km of water distribution piping is made up of approximately 50.9km of Asbestos Cement pipe (46%), 29 km of PVC/HDPE pipe (27%), 18.0 km of Ferrous (steel/iron) pipe (16%), 11 km of reinforced concrete pipe (Hyprescon, 10%), and 1.2 km of copper or unknown pipe (1%). Pipe sizes range from 575mm (22”) to 100mm (4”). The system map is shown in Appendix A.

Figure 8 Distribution pipe materials breakdown.

5.1 PRESSURE ZONES There are seven water pressure zones in the City of Castlegar’s distribution system and these are referred to as follows: 1 North zone; 2 Woodland Drive zone; 3 Park zone; 4 School zone; 5 Upper Bench zone; 6 Blueberry zone; 7 Twin Rivers zone. The system operating pressure ranges from 40psi to approximately 150psi.

5.2 PUMP STATIONS AND RESERVOIRS

(1.) MEADOWLARK PUMP STATION The Meadowlark pump station consists of eight high capacity pumps, which are split into two stages. The three Stage I pumps assist in filling the Meadowlark Reservoir. The five Stage II booster pumps are utilised to fill the Park and School reservoirs, respectively.

(2.) MEADOWLARK RESERVOIR The Meadowlark reservoir is the City’s central distribution point and is located approximately 6 kilometers downstream of the treatment facility. The Meadowlark reservoir is a 22m diameter concrete tank of 2.25 Megaliter (ML) liquid volume. The top water level is 497m.

(3.) PARK PUMP STATION & UPPER BENCH RESERVOIRS (A, B & C) The Park pump station comprises of four high capacity pumps. The four pumps are referred to as the Stage III pumps. The Park reservoir level stops and starts the Stage II pumps at Meadowlark. The Stage III pumps at Park Station fill the upper bench reservoirs

(4.) UPPER BENCH RESERVOIRS A. Meadowbrook Reservoir (steel tank) B. Merry Creek Reservoir (concrete tank) C. Blueberry Reservoir (concrete tank)

(5.) GRANDVIEW BOOSTER STATION The Grandview booster pump station is equipped with two small and two large booster pumps. The pumps provide additional operating pressure for the Grandview Subdivision neighbourhood.

(6.) HIGHLAND DRIVE BOOSTER STATION The Highland Drive pump station is equipped with one booster pump to increase the pressure to the residents of Highland Drive in times of peak demand on the water distribution system.

(7.) SCHOOL RESERVOIRS (1 & 2) School Reservoir 1 is a concrete tank reservoir, on 24th Street. School Reservoir 2 is a larger steel tank reservoir, that is slated for decommissioning when the Park Reservoir replaces it.

(8.) AIRPORT RESERVOIR & PUMP STATION Airport reservoir is a concrete tank, on an independent groundwater source. It was constructed in the 1960s. There is also a 30 gallon/minute pump at this location, which has since been dedicated to the Ministry of Forestry fire-fighting efforts. There is a City of Castlegar sampling site here, off the City of Castlegar potable water system (3/4” sampling line).

5.3 WATER SYSTEM CONTROL The City of Castlegar currently utilizes a computerized SCADA system with its water treatment and distribution process.

SCADA is an acronym for “Supervisory Control and Data Acquisition”, which is a computer system for gathering and analyzing real time data.

SCADA systems are used to monitor and control a treatment plant or equipment (eg. pumps and valves). The SCADA system continuously monitors the City of Castlegar’s WTC and the water distribution system for the following parameters:

1 Raw Water Turbidity; 2 Treated Water Turbidity; 3 UV Transmittance; 4 UV dose; 5 Chlorine Residual; 6 Water Flow; and 7 Alkalinity (pH), (not online yet, future). In the case of a significant change in outputs or a component failure, an alarm is sent to the mobile phones of the appropriate personal and after-hours the alarm is sent to the City of Castlegar emergency phone. This gives the City of Castlegar confidence that all SCADA alarm conditions will be investigated promptly at the Water Treatment Center and throughout the distribution system. The SCADA system has been calibrated/upgraded every year since 2012 to ensure control of the potable water system is kept current. The free chlorine residual is continuously analyzed by online instrumentation throughout the water distribution system and is transferred to the City’s SCADA system. The SCADA system will alarm to staff cell phones if the chlorine concentration falls outside of the predetermined ranges.

5.4 MONITORING PROGRAM IN 2017 WATER TREATMENT MONITORING

Continuous Monitoring:

· Turbidity (NTUs – high set-point = 1 NTU; high-high set-point = 3 NTU). · Chlorine Residual (at Blueberry, Airport, Park Pump House, Meadowlark Pump House, & Water Treatment Centre…the CL2 set-points vary throughout system; at WTC alarm settings are for low set-point = 0.50mg/L; and low-low set-point = 0.30mg/L) and if required, the online chlorine analyzers are also re-calibrated to ensure proper trending and alarm capabilities of the City’s SCADA system. · UV Light - Transmittance (low set-point - 90%UVT; low-low set-point = 88%UVT) this sets the Disinfection Dosage time/strength etc. · pH (monitored by staff for information only, not adjusted by treatment process).

Daily Monitoring:

· Operators check monitoring equipment’s performance and alarm set-points, and often take sample by hand. Chlorine residual is also checked at Airport five days per week. DISTRIBUTION WATER QUALITY MONITORING

Weekly Bacteriological Testing:

· As required under the Operating Permit, City staff perform weekly bacteriological testing for E-coli and Total Coliform bacteria throughout the distribution system. · Sampling locations are as follows: 1) Water Treatment Center (raw water); 2) Meadowlark Pump Station; 3) Civic Works Yard; 4) Airport Reservoir; and, 5) Blueberry Reservoir. · Every week, these five samples are sent to a third-party lab for bacteriological testing. See Appendix B for complete set of laboratory test results. · In 2017, only two (2) tests came back with counts greater than zero. On January 30th, the Public Works Yard water sample scored 1 count/100mL of Total Coliforms. It was retested within 48 hours, and was confirmed to be negligible (less than 1/100mL). On August 21st, the same location tested positive for 1 count/100mL and was also retested and confirmed to be negligible (less than 1/100mL). · In 2017, all water sample tests from the distribution system were negative for E.coli.

2017 ANNUAL WATER QUALITY REPORT WSP Project No. WSP NO. 181-09051-00 CITY OF CASTLEGAR Page 17

Quarterly Testing:

· The City performs quarterly “General Potability” testing of source (raw) water.

Bi-Annual Testing:

· The City also completes bi-annual testing of raw water at the WTC, for Cryptosporidium and Giardia with a third-party laboratory. In 2017, both test samples came back negative for cysts/oocysts (0.00 detected). · Bi-annual testing is done for Trihalomethanes (THM) at the ends of the distribution system (at Blueberry reservoir and at Airport reservoir, Figure 9 below). · Bi-annual testing is also completed for Haloacetic-Acids (HAAs) at the mid-point of the distribution system (at the Park Pump Station, Figure 9 below). · Chlorophyll A is monitored from approximately August through October each year. Chlorophyll A is signal of algae growth patterns.

5.5 SYSTEM MAINTENANCE IN 2017 WATER TREATMENT CENTER MAINTENANCE · Daily: WTC is inspected to ensure that UV and chlorination disinfection systems are operating correctly. · Monthly: magnetic flow meter and UV reference sensor are validated. · Annually: UV reference probes are also validated by a third party. PUMP STATION MAINTENANCE · Daily: Meadowlark Pump Station & Park Pump Station are inspected daily. · Weekly: inspections of Grandview booster station. · Monthly: Highland Drive booster station inspected during summer (June to Sept.). · All Pumps and Motors are serviced as per the manufactures specifications. PRV STATION MAINTENANCE · Weekly: inspections of the City’s PRV stations, monitoring for leaks and verification of proper operation of all equipment. RESERVOIR MAINTENANCE · Daily: all reservoir levels are monitored on the City’s SCADA system, and alarms will be triggered if reservoir levels change drastically or a “high-level” or “low-level” situation occurs. · Bi-Weekly: inspections of all reservoirs to ensure that the sites are secure and that the equipment is operating as intended. · All Pumps and Motors are serviced as per the manufactures specifications.

5.5.1 SITE SECURITY A combination of measures is utilized to provide security for the distribution system. The WTC building(s) have been equipped with a security system, alarms, security cameras and has security guards (from Celgar mill). All City Reservoirs have been fenced with locked ladder access. Both Meadowlark and Park Pump Stations have been equipped with security systems and security cameras. All Pressure Reducing Valve station sites are also securely locked.

5.5.2 UNI-DIRECTIONAL FLUSHING (UDF) PROGRAM In 2017, the City of Castlegar staff focussed their flushing efforts on the North end of the City (to Twin Rivers area) due to recognising that the north end (closer to the source intake) has been more prone to algae buildup. Staff performed UDF flushing on the water system, except for the community of Blueberry. All fire hydrants are inspected and flushed annually.

· Historically (approximately 1980-2004) the City would flush dead-end watermains. Due to the extremely high volume of residential water quality complaints generated from flushing, dead-end watermain flushing work was suspended in 2004.

· In approximately 2001 the Arrow Lakes provincial lake fertilization program begins, in support of sports fishing industry. The program has adverse effects on the City’s water quality and distribution system.

· In 2013, the City worked with a consultant (Urban Systems) to create a Uni-Directional Flushing (UDF) program. It was quickly identified that north Castlegar (downtown) didn’t have enough water system valves to achieve true UDF. The City worked with the consultant to complete the water system mapping project.

· In 2014, the City spent $110,000 installing water system valves in north Castlegar and continued to work with the consultant on water modelling and developing a draft UDF Program (routes/plans).

· In 2015, the City spent an additional $40,000 installing water system valves and continued working on verifying the draft UDF routes.

· In 2016, City staff flushed north Castlegar (Downtown).

· The City implements summer sprinkler regulations from June 15th to September 15th each year, and UDF work is not permitted during this period.

The City’s water system currently has approximately 250 UDF routes. Due to limited utilities staff, the City does not have the capacity to perform UDF on the entire water system each year. One concept that is being considered for the formal UDF Program is to establish three quadrants or “flushing-zones”. The City anticipates a schedule whereby each quadrant would be flushed on a three or four-year cycle, depending on staff work loads, alternating between “flushing zones”. The community of Blueberry and north Castlegar are scheduled to be flushed in 2018.

2017 ANNUAL WATER QUALITY REPORT WSP Project No. WSP NO. 181-09051-00 CITY OF CASTLEGAR Page 20

An additional constraint on the UDF program has been disposal of the flushing water, since many roadways do not have curb & gutter. Areas with steep banks are prone to erosion problems, and therefore Cross- flushing water must be collected and trucked to another location for disposal. Connections

Plumbing cross-connections constitute a serious public 5.5.3 CROSS-CONNECTION CONTROL health hazard. Simply put, a PROGRAM cross-connection occurs when potable water comes into The City has developed and adheres to a Cross- contact with non-potable water Connection Control Program. This program was supplies. established to identify high risk water service connections that could compromise/contaminate the Because private plumbing City’s water supply. High risk service connections are systems are often altered, cross- required to install back-flow prevention devices. connection control programs require ongoing investment.

Regulatory policies regarding existing and future service connections are essential on top of educational programs to prevent cross-connection hazards.

The City’s cross-connection control program has a history of success and a priority step going forward is to reinvigorate the program to ensure safe reliable drinking water supply.

6 CUSTOMER SERVICE There were no watermain breaks in 2017; however, due to the extra cold winter season there were five calls to repair frozen water services. And throughout the year, eight ¾ inch water service connections had to be repaired for leaks located within the City’s right-of-way.

The City of Castlegar’s water utility did not issue any public Boil Water Advisories or Notices during 2017

6.1 CUSTOMER COMPLAINTS The following reports/complaints from water customers were received by the City of Castlegar’s Civic Works Department during the 2017 billing year:

FEBRUARY 3, 2017 – One resident called in to the City’s Civic Works Department to complain about “excessive chlorine odour and taste” in their drinking water.

JULY 28, 2017 – One customer called the City to report “poor water taste and odor”. It was suspected that this might be an algae issue. The City asked the homeowner to call back to discuss further; however, they never did call back.

JULY 31, 2017 – One customer reported “very low water pressure”. The matter was investigated and was found to be caused by their household filter clogging (due to algae/sediment).

OCTOBER 4, 2017 – Another customer called in to comment that “the water in the downtown area is cloudy, with a foul taste and odor”. City staff followed up with this individual.

The Civic Works Department received a few other complaints about high turbidity or coloured water; however, this was typically following water distribution system maintenance work in their neighbourhoods. There are no guidelines for drinking water colour, as this is more of an aesthetic quality. City staff always advise these customers to run their water for 15 minutes and if the water does not clear up, to call the City of Castlegar Civic Works Department back for further directions and assistance. To reduce these types of complaints in the future, the City is continuing to develop and implement the City of Castlegar’s UDF program.

8 EMERGENCY RESPONSE PLANNING Emergency response planning is an essential part of the governance of a drinking water system. As required under the City’s operating permit, a Drinking Water - Emergency Response Plan (ERP) was drafted in 2014. The 2014 draft ERP was reviewed by IHA. The goal of the emergency response plan is to identify potential emergency conditions that could occur and have documented response procedures in place. The 2014 ERP has not yet been endorsed by the City of Castlegar’s Fire Department, or the RCMP. This Emergency Response Plan is scheduled for completion in 2019. The revised ERP will also expand on all requirements and procedures for utilizing the North Well as an Emergency Water Source.

8.1 EMERGENCY NORTH WELL SYSTEM The City of Castlegar maintains a groundwater well located adjacent to City Hall that can be brought online in case of a water source emergency. Such an emergency has not occurred in the recent past. The well and pump are rated at approximately 1,100 USGPM, and are regularly maintained in case of an emergency. The well is equipped with chlorine injection and connection to the distribution system. Consultation with IHA and communication with the residents of Castlegar would be required prior to running the emergency well water system. The well (and associated valves/appurtenances) was operated monthly in 2017 to ensure that it is ready for use in case of emergency. In 2017, a full comprehensive raw water analysis for the North Well was completed (see Appendix D); and a regular flushing program has been developed to include the North Well. The plan to provide a physical separation for the North Well from the rest of the distribution using a removable stub of pipe (spool) was completed in approximately 2009. In 2018, the City plans to install a soft-starter, and transfer switch and genset plug on the North Well. If the Celgar mill is shut down (in case of forest fire or other emergency) then there will no longer be a power supply to the water pumps, and if the supply pumps shut down, then Castlegar’s drinking water system will shut down as well. The North Well is no longer an approved or registered drinking water source and it needs to be re-tested and re-certified, with full geotechnical investigation and hydro-geotechnical assessment to be completed. It could be used in an emergency, with a full City-wide, mandatory boil water notice in place.

REPORTED TO Castlegar, City of WORK ORDER 7010430 PROJECT General Potability REPORTED 2017-01-17

The following section displays the quality control (QC) data that is associated with your sample data. Groups of samples are prepared in fibatchesfl and analyzed in conjunction with QC samples that ensure your data is of the highest quality. Common QC types include:

Ł Method Blank (Blk): Laboratory reagent water is carried through sample preparation and analysis steps. Method Blanks indicate that results are free from contamination, i.e. not biased high from sources such as the sample container or the laboratory environment Ł Duplicate (Dup): Preparation and analysis of a replicate aliquot of a sample. Duplicates provide a measure of the analytical method™s precision, i.e. how reproducible a result is. Duplicates are only reported if they are associated with your sample data. Ł Blank Spike (BS): A known amount of standard is carried through sample preparation and analysis steps. Blank Spikes, also known as laboratory control samples (LCS), are prepared from a different source of standard than used for the calibration. They ensure that the calibration is acceptable (i.e. not biased high or low) and also provide a measure of the analytical method™s accuracy (i.e. closeness of the result to a target value). Ł Standard Reference Material (SRM): A material of similar matrix to the samples, externally certified for the parameter(s) listed. Standard Reference Materials ensure that the preparation steps in the method are adequate to achieve acceptable recoveries of the parameter(s) tested.

Each QC type is analyzed at a 5-10% frequency, i.e. one blank/duplicate/spike for every 10 samples. For all types of QC, the specified recovery (% Rec) and relative percent difference (RPD) limits are derived from long-term method performance averages and/or prescribed by the reference method.
