The invert of the intake is 2.75 m below the top of the canal wall. Pre-chlorination for zebra mussel control is initiated when the water temperature reaches 12 C. A raw water chlorine analyzer is located at the low lift pump raw water suction well. Raw water quality has been characterized as having moderate colour, low to moderate alkalinity & hardness, and moderate levels of organic carbon and nitrogen. The quality of the Trent River changes due to seasonal fluctuations in temperature and upstream activities including, but not limited to, the spring freshet, rainfall events, storm water runoff, agricultural activities and spills. Inputs from upstream sources can increase the amount of nutrients entering the watercourse. Increased nutrient loading can result in increased algae growth and the potential for the creation of taste and odour concerns at the water treatment plant. Storm-water runoff can also cause rapid fluctuations in turbidity levels entering the plant.

Comments:The Campbellford Water Treatment Plant is a conventional water treatment system. Zebra mussel control is initiated in the summer months through the use of diffused chlorine gas at the intake. The low lift pumping station consists of a travelling screen, low lift storage well and three vertical turbine pumps. The primary coagulant, polyaluminum chloride (Sternpac), is added at the low lift header. Coagulation, flocculation and settling occur in two parallel solids up-flow clarifiers equipped with tube settlers and an automatic sludge removal system. Settled sludge from the clarifiers is directed to a backwash waste settling tank for treatment. Treated water from the clarifiers is filtered through two dual media, constant rate, gravity filters. The filter media consists of 600 mm of activated carbon on 250 mm of silica sand. Filter beds are backwashed every two days to a maximum of three days running, depending on effluent turbidity and headloss. Wastewater from backwashing is discharged to a settling tank. Supernatant in the settling tank is discharged to the storm sewers following an eight hour settling period. Settled sludge from the settlingtank is discharged to the sanitary sewer. On-line analyzers monitor the turbidity levels of the raw and filtered effluent.Primary disinfection of the effluent is achieved by twin ultraviolet irradiation units which consists of two reactors in parallel (one duty, one standby), with a light flux density of at least 40mJ/cm. The water stream is then disinfected by the injection of chlorine gas at the clear well and can be augmented on the high lift discharge line prior to distribution.An online chlorine analyzer monitors the treated water chlorine levels prior to the treated water being pumped to the onsite reservoirs newly commissioned ~2018. The high lift pumping station now located in the new reservoir buildingconsists of three vertical turbine pumps (two duty and one standby), that pump from a 330 m3 clearwell, interconnected to the new twin reservoir cells with a storage capacity of 1470 m3. A chlorine booster station is located at the High Street storage reservoir where sodium hypochlorite is used to maintain free chlorine residual levels in the distribution system.

INSPECTION SUMMARY:

Introduction

• The primary focus of this inspection is to confirm compliance with Ministry of the Environment, Conservation and Parks (MECP) legislation as well as evaluating conformance with ministry drinking water related policies and guidelines during the inspection period. The ministry utilizes a comprehensive, multi-barrier approach in the inspection of water systems that focuses on the source, treatment and distribution components as well as management practices.

This drinking water system is subject to the legislative requirements of the Safe Drinking Water Act, 2002 (SDWA) and regulations made therein, including Ontario Regulation 170/03, "Drinking Water Systems" (O.Reg. 170/03). This inspection has been conducted pursuant to Section 81 of the SDWA.

This report is based on a "focused" inspection of the system. Although the inspection involved fewer activities than those normally undertaken in a detailed inspection, it contained critical elements required to assess key compliance issues. This system was chosen for a focused inspection because the system's performance met the ministry's criteria, most importantly that there were no deficiencies as identified in O.Reg. 172/03 over the past 3 years. The undertaking of a focused inspection at this drinking water systemdoes not ensure that a similar type of inspection will be conducted at any point in the future.

This inspection report does not suggest that all applicable legislation and regulations were evaluated. It remains the responsibility of the owner to ensure compliance with all applicable legislative and regulatory requirements.

On May 14, the undersigned Ministry of the Environment, Conservation & Parks Water Inspector initiated the inspection of the Campbellford Drinking Water System (DWS) for the purpose of performing a Focused, Announceddrinking-water system inspection. Also, on July 14, 2020, the undersigned conducted a field inspection of the waterworks in the accompaniment of Mr. Todd Kerr - Operator In Charge. It is understood the Mr. Scott White, has been identified as the General Manager of Infrastructure Renewal and Public Works Administration. Further, it is understood that Mr. Scott Campbell is the Overall Responsible Operator (ORO) and Head Water Operator. Data was provided electronically by Mr. Scott Campbell as requested.

The Corporation of the Municipality of Trent Hills is the owner of the Campbellford Drinking Water System and recognized as the Operating Authority of the entire drinking system, including the distribution system. Under Ontario Regulation 170/03, a large municipal residential system is a municipal drinking-water system that serves a major residential development and serves more than 100 private residences. A major residential development is defined in the Safe Drinking Water Act as a development of six or more private residences on one or more properties. The Campbellford Drinking Water system serves approximately ~3800 residents, and under the Regulation is therefore considered to be a large municipal residential system, subject to the Regulation.

The drinking water inspection included a review of the treatment plant and distribution system documentation, for the period of July 1, 2019 to the end of April of 2020, hereafter referred to as the inspection period in this report.

Last year's inspection did not identify any issues of non-compliance, but did recommend one (1) Best Practice Issue and Recommendation, as well as three (3) other recommendations within the section entitled "Other Inspection Findings".

Inquiry this year with Mr. Scott Campbell - Head Operator and past inquiry with Mr. Scott White, General Manager of Infrastructure Renewal and Public Works Admin indicates that the Municipality of Trent Hills does not have a "Harmful Algae Bloom" (HAB) monitoring plan. However, the Municipality reports that they have been in consultation with the MECP in this regard. Initial reports based upon that consultation from the Municipality indicates that they may be exempt from their Municipal License including a HAB monitoring plan given that their source water, i.e: the Trent river, at the Campbellford WTP intake location has essentially been free of blue/green algae outbreaks historically. That being said and for information purposes the DWS Owner is reminded that the Ministry of the Environment, Conservation & Parks has provided notice to all Municipalities in a letter, dated May 10, 2019, that utilize surface water as their source water that the Ministry is incorporating the requirement for a monitoring, sampling and reporting plan for harmful algae blooms into their Municipal Licenses as a new standard condition during upcoming license renewals.

Capacity Assessment

• There was sufficient monitoring of flow as required by the Municipal Drinking Water Licence or Drinking Water Works Permit issued under Part V of the SDWA.

• The owner was in compliance with the conditions associated with maximum flow rate or the rated capacity conditions in the Municipal Drinking Water Licence issued under Part V of the SDWA.

The Campbellford drinking water system is to be operated in accordance with Municipal License 150-102, ScheduleC, section 1.0: System Performance, section 1.1 - Rated Capacity, (Table 1) stipulating a maximum flow rate into the distribution system of 6,800 M3/d. The treated water max day flows from July 1, 2019 to April 31, 2020 ranged from 947 M3/d (Jan. 2020) to 4037 M3/d (Sept. 2019), equating to ~14% - 59% of plant rated capacity.

Treatment Processes

• The owner had ensured that all equipment was installed in accordance with Schedule A and Schedule C of the Drinking Water Works Permit.

• Records indicated that the treatment equipment was operated in a manner that achieved the design capabilities required under Ontario Regulation 170/03 or a Drinking Water Works Permit and/or Municipal Drinking Water Licence issued under Part V of the SDWA at all times that water was being supplied to consumers.

According to Municipal License 150-102 the Campbellford water treatment plant's primary disinfection processes must provide a minimum of 2.0 log removal/inactivation (R/I) of Cryptosporidium (Crypto) oocysts, 4.0 log R/I Giardia lamblia and 5.0 log R/I viruses, before the water is delivered to the first consumer, although these log removal requirements have been reviewed by Permissions Branch and the amended Municipal License (Issue #4) dated May 21, 2019, prescribes that the Works is obligated to provide 2.0 log removal/inactivation (R/I) of Crypto, 3.0 log R/I Giardia lamblia and 4.0 log R/I viruses, before the water is delivered to the first consumer. At least 0.5 log R/I of Giardia cysts and 2.0 log R/I of viruses must be provided through disinfection. The Campbellford Water Treatment System has been credited with 2.0 log removal /inactivation of Crypto, and a 2.5 log removal/inactivationof Giardia cycts and 2.0 log removal of Viruses from the filtration processes, as well as 2 log R/I of Crypto, and a 3.0 log removal/inactivation of Giardia cycts and 2.0 log removal of viruses, through the ultraviolet light disinfection process, based on their most recent Municipal License - Schedule E - Section 1. At least 2.0 log R/I of Viruses shall be obtained through the disinfection processes attributed to the new ~1770 m3 reservoir, as backup to the UV system. Records reviewed indicate that CT/treated water chlorine residuals for the most part remained well above above the alarm set point of 0.80 ppm, over the inspection period. The Works Owner completed daily Giardia CT calculations, which were provided for review and ranged from 2.9 log (Nov. & Dec./19) to 52.2 log (Sept./19), while minimum Virus log removals ranged from 25.1 log - 371.2 log. A couple of records captured yielded Giardia removals of 0.00 log, however in review of the anomalous data these were consequential to analyzer calibrations & maintenance activities. Aside from this, according to records the lowest recorded chlorine residual leaving new

clearwell was 1.21 mg/L, during the month of April 2020. Further, since it is acknowledged that the Campbellford WTP utilized twin Sentinel UV irradiation units post January 2019, the Owner would only be required to provide a maximum disinfection over this inspection period of 1 log R/I of viruses to achieve primary disinfection, providing UV dosages were satisfactory during these periods, as was the case, aside from several events where the UV dosages dipped less than 40 mj/cm2 during the months of July-Oct & Dec. - 2019, all consequential to UV rotations,diesel operation &/or power outages. Primary disinfection (CT) calculations completed by the undersigned for the month of February 2020 utilizing the worst case variables of 1.39 ppm, regarding the reservoir free chlorine residuals, as well as minimum clearwell volume of ~842 m3, and maximum flow rate for the month of 3.327 m3/min,and a baffle factor of 0.30, yielded a CT Achieved value of ~ 105.5 mg*min/L. The required CT value required, according to the Ministry's - Procedure For Disinfection of Drinking Water In Ontario indicates a CT Required value of ~53 mg*min/L to address 0.5 log R/I of Giardia, based on conservative values, using a raw water temperature of ~.5 degrees C and a pH value of ~8. Further, according to daily CT data provided by the Works Owner, CT for the month ranged from 292.7 - 599 mg*min/L, based upon chlorine alone. Also, in review of the filter performance data, records indicate that the drinking water system consistently achieved their "95th percentile" target of 0.30 NTU, in accordance with the Ministry's - Procedure For Disinfection of Drinking Water In Ontario. Also, the UVT data provided indicates that these values ranged from 88.9%-91.3% over the inspection period, on the low end.

• Records confirmed that the water treatment equipment which provides chlorination or chloramination for secondary disinfection purposes was operated so that at all times and all locations in the distribution system the chlorine residual was never less than 0.05 mg/l free or 0.25 mg/l combined.

Secondary chlorine residual values are collected via a continuous monitoring unit located at the water tower, and during routine bacteriological sample collection efforts. During this inspection period the tower analyzer was not utilized and staff collected samples twice weekly 48 hours apart from July to mid September - 2019. According to records the lowest reported secondary disinfectant chlorine residuals based upon grab samples collected occurred in August of 2019, yielding a value of 0.12 ppm, and the highest reported value was 2.16 ppm, as collected in November of 2019. The lowest value retrieved from the water tower Prominent continuous monitoring analyzer was1.03 ppm, that was captured in January of 2020.

• Where an activity has occurred that could introduce contamination, all parts of the drinking water system were disinfected in accordance with Schedule B, Condition 2.3 of the Drinking Water Works Permit.

A total of two (2) distribution system repairs occurred over the inspection period under review. Records provided indicate that corrective actions were in accordance with applicable legislation. The events occurred on November 21 & 24, of 2019.

• The primary disinfection equipment was equipped with alarms or shut-off mechanisms that satisfied the standards described in Section 1-6 (1) of Schedule 1 of Ontario Regulation 170/03.

The Sentinel UV units are equipped with multiple major/minor alarms &/or lock-outs for such things as; Emergency stop, lamp failure, comm loss, power interlock on high voltage, low water flow, low UV dose, UV dose off-spec low, high water temp, reactor leak, quartz cleaner failure to cycle, UV intensity out of range, as well as PLC dose pacing.Further, the Sentinel UV units will shut off and halt filter effluent flow should a UV dose <40 mj/cm2 be detected andsustained. According to Municipal License # 150-102. Sch. E, Condition 1.0 - Primary Disinfection Pathogen Log Removal/Inactivation Credits, outlines specific details that must be adhered to, which include calibration of the UV sensors at least on a monthly basis against a reference sensor. Further, the ultraviolet light disinfection equipment shall have a feature that ensures that no water is directed to users of water treated by the equipment or that causesan alarm to sound in the event that the equipment malfunctions, loses power or ceases to provide the appropriate level of disinfection. The UV system is set up that in an alarm condition the filter effluent valves closes and the duty UV reactor is inhibited so no water is treated during the condition. The standby unit powers up and the filter effluent valves do not open until the standby unit has reached the dosage setpoint Records provided indicate that the necessary monitoring & actions regarding the UV system is being completed. According to UV disinfection records,dosages for both units ranged from 0 mj/cm2 to 84.3 mj/cm2, however the events where a zero (0) mj/cm2 dose was recorded, were consequential to power outages/flickering, UV rotations, filter backwashing, power &/or transfer

of line power to the diesel genset, and not indicative of the level of disinfection applied to the finished water. It is further worth noting that the Municipality has maintained an elevated chlorine residual within the plant reservoir to ensure that primary disinfection is achieved, should the UV dose dip below 40 mj/cm2.

Treatment Process Monitoring

• Primary disinfection chlorine monitoring was conducted at a location approved by Municipal Drinking Water Licence and/or Drinking Water Works Permit issued under Part V of the SDWA, or at/near a location where the intended CT has just been achieved.

It is understood that prior to the upgrades the drinking water system utilized a Prominent free available chlorine residual analyzer (CT analyzer), located on the suction side of the highlift pumps, although at this time the treatment system included ultra violet irradiation units to support the lions share of primary disinfection needs. At the time of this years inspection the upgrades had been finished, with a Hach chlorine residual analyzer monitoring residuals from the highlift west well. It should be mentioned that this DWS has the capability & does inject chlorine post this analyzer and prior to delivery to consumer base (within the highlift header) for purposes of ensuring adequate secondary disinfectant levels.

• Continuous monitoring of each filter effluent line was being performed for turbidity.

Past inspections have confirmed two (2) Hach 1720-E turbidity monitoring units, alarmed @ 0.30 NTU, monitoring the filtered water from the sand/GAC capped filters. In addition the raw & treated water are also being monitored for turbidity via Hach turbidity analyzers.

• The secondary disinfectant residual was measured as required for the distribution system.

During the inspection period the Works Owner did undertake a major capital budget refurbishment of the water tower. During this time the Works Owner adopted a grab sampling routine of monitoring the free available chlorine residual from July to mid September of 2019, with continuous monitoring of chlorine residuals being recorded post September 10, 2019. The grab sampling was completed as per O.Reg. 170/03 - Schedule 7, subsection 7-2(4). Results from grab sampling to include results of chlorine residual monitoring captured during routine microbial sampling ranged from 0.10 ppm - 2.14 ppm and afterwards based upon continuous monitoring from the water towerProminent free available chlorine residual analyzer and grab sampling efforts, values retrieved ranged from 0.12 ppm - 5.01 ppm.

• Operators were examining continuous monitoring test results and they were examining the results within 72 hours of the test.

It has been reported that SCADA trends are reviewed every work day and at least every 72 hours, post wknds. It isimportant to note in review of the data compiled within the monthly reports and provided for review yielded multiple data sets (min/max & means) that fall outside of what would be considered acceptable for compliance purposes. Recommendations during this year's inspection and prior years have suggested that the Municipality continue to improve upon their current methods of data capture and explanations by way of either accompanying the monthly data sheets & data of concern with data that was indicative of water quality that was distributed to the consumer base or next treatment stage "or" create a spreadsheet where comments and compliant data can be entered to include explanitory information. Either format should include the real min/max & mean data set for the reporting period that is indicative of water sent to the consumer, the reason for the occurrence, actions taken to resolve and prevent, (where possible), as well as the number of occurrences where a parameter fell outside of acceptable compliance limits, regarding raw water flows, filter effluent turbidity, primary and secondary disinfectant chlorine residuals and UV dosages, as applicable. At present, beyond the min/max & mean continuous monitoring data generated at the facility the Municipality supports this with a set of "anomalous data sheets". These sheets do address many of the concerns raised by the author of this report, such as cause of event, if water was flowing to next treatment stage and in some cases what the real data was, but fall short in some key areas. For inspection purposes additional records are needed to confirm compliance in many cases outside of the continuous monitoring

data and the anomalous data sheets provided. The Work's Manager overseeing operations at their drinking water facilities asserts that all relevant compliance data not found within continuous monitoring and anomalous data sheets can be obtained with the facility logbooks, for example. The Ministry is certainly not opposed to reviewing logbooks, however, when the sheer number of anomalous data sets captured are substantial, then this approach is unrealistic from a time management perspective for both Ministry personnel and of course that of Municipal personnel that would be required to assist with this activity. In an effort to address this Ministry staff may make recommendations to Municipalities &/or Operating Authority where alternative data capture methods have been identified that could improve upon existing information transfer to the Ministry for compliance purposes, as has been the case here. In fact a meeting with MECP staff and the Municipality was convened on June 2/20 that touched on Ministry concerns, among other things. It is recommended that the Municipality consider creating a spreadsheet that could accompany continuous data captured and provided during compliance inspections or simplyinclude the sought after data alongside the continuous monitoring data sheets, where-ever erroneous or suspect data has been compiled.

• All continuous monitoring equipment utilized for sampling and testing required by O. Reg.170/03, or Municipal Drinking Water Licence or Drinking Water Works Permit or order, were equipped with alarms or shut-off mechanisms that satisfy the standards described in Schedule 6.

The Municipality provided a listing of alarms. Last years compliance inspection identified multiple continuous monitoring analyzers within the Campbellford DWS. The raw, treated and distribution system water chlorine (Cl2) residuals were each being monitored by Hach &/or Prominent continuous monitoring equipment. In addition to these units, Hach turbidity analyzers, were capturing trends from the raw, filtered and finished waters. Alarm set points were identified as follows;

Coagulant pump fault alarm - Low Lift lock-out

Filter Effluent Turbidity Alarm/lockout filter effluent valves - >0.3 NTU

Treated water turbidity alarm >0.7 NTU

Reservoir Cl2 Alarm <0.8 mg/L

Finished Cl2 Alarm - 0.80 mg/L & lock-out

High Lift Lock out - Turbidity >0.7 NTU, Low Cl2 <0.8 mg/L, High Cl2 @ >3.0 mg/L and Low LRV <10.00 log

UV Lock-out - LoLo dose <40 mj/cm2 UV Alarm @ Low UV dose <45 mj/cm2

Secondary Disinfection Hi Alarm - >3.0 mg/LSecondary Disinfection Lo Alarm - <0.8 mg/L

• Continuous monitoring equipment that was being utilized to fulfill O. Reg. 170/03 requirements was performing tests for the parameters with at least the minimum frequency specified in the Table in Schedule 6 of O. Reg. 170/03 and recording data with the prescribed format.

• The owner and operating authority ensured that the primary disinfection equipment had a recording device that continuously recorded the performance of the disinfection equipment.

Last years compliance inspection report notes that Mr. Campbell advised that the new UV units poll data to the PLCcontinuously every 30 seconds, with data being captured every hour, as per records of UV intensity and dosages

provided. UV Transmittance values are captured daily according to records. According to Municipal License #150-102, Sch. C, Condition 1.6.2, states; In addition to any other sampling, analysis and recording that may be required,the ultraviolet light disinfection equipment shall test for the test parameters set out in column 4 of the same row at a testing frequency of once every five (5) minutes or less, except for UV transmittance (manual grab test parameter), and record the test data at a recording frequency of once every four (4) hours or less.

• All continuous analysers were calibrated, maintained, and operated, in accordance with the manufacturer'sinstructions or the regulation.

Records provided indicate that on a "quarterly" basis (Aug/Nov -19 & Feb-20) the chlorine residual analyzers & the turbidity analyzers are calibrated in-house, by staff, to include replacement of the electrolyte & membrane caps on the chlorine monitoring units, and utilizing the Stablcal 20 NTU formazin (primary standard) for the turbidity units. According to literature retrieved from the web the Prominent chlorine residual analyzers only require calibration when measuring at the lower end of the measuring range 0 - 0.5 ppm, while the Hach 1720 E low range turbidity meters require calibration prior to initial use, after any significant maintenance or repairs, and at least once every three (3) months during normal operations.

• All UV sensors were checked and calibrated as required.

Municipal Drinking Water License #150-102, Issue 4, Schedule E - "Pathogen Log Removal/Inactivation Credits", Section 1.0, obligates the Works Owner to check the duty UV sensors at least monthly against a reference sensor or as per O/M Manual. Further, the calibration ratio shall be less than or equal to 1.2, and if the calibration is greater than 1.2, than the sensor shall be replaced with a calibrated UV sensor or a UV sensor correction factor shall be applied while the problem with the UV sensor is being resolved. Records provided indicate that the sensors are being checked each month under review. It has been reported that post calibration values must be within the limits of 0.95 - 1.05, and if outside of this tolerance the operator interface will display a "Calibration error",requiring the calibration sequence to be repeated.

• When the primary disinfection equipment, other than that used for chlorination or chloramination, has failed causing an alarm to sound or an automatic shut-off to occur, a certified operator responded in a timely manner and took appropriate actions.

A total of 28 call-ins were acted on over the inspection period, where a 1 hour responce is expected. Of those, five (5) were relating to issues with the ultra-violet irradiation units.

Other Inspection Findings

• The following issues were also noted during the inspection:

1.) It is recommended that the Municipality consider creating a spreadsheet that could accompany continuous datacaptured and be provided during compliance inspections or simply include the sought after data alongside the continuous monitoring data sheets, where-ever erroneous or suspect data has been compiled.

2.) It is recommended that the Municipality investigate options to minimize the capture of misinformation coincidental to the operation or the diesel genset.

3.) It is recommended that the Works Owner improve upon the current format for monthly UV Alarms and include allparameters; date, time, duration, volume & corrective actions for each alarm event. As previously advised please ensure that future renditions of the UV Alarms Monthly Summary Report include UV alarms for UV equipment malfunctions, loss of power or failure to meet any of the monitoring criteria in Table 4. If there is an alarm condition for any of the above it must be included in the monthly summary report, even if the unit automatically switched over to the standby unit. If there was no untreated water that flowed through the unit then the volume treated is simply reported as zero.
