3 February 21, 2018 Dear Water Consumer: Water Services is pleased to provide its 2017 Annual Water Quality Report for the Region of Waterloo Rural and Integrated Systems to our Consumers as required by Regulation 170/03 of the Safe Water Act. The report contains useful information related to water quality in the Region, and is available annually by February 28, on the Region s internet website at: The link above is also where the Annual Summary Report required under Schedule 22 of Regulation 170/03 will be available for inspection. In 2016, the Ministry of Environment and Climate Change (MOECC) added one pesticide, 2- Methyl-4-chlorophenoxyacetic acid (MCPA) to the list of required testing. In 2017 the MOECC updated Regulation 170/03 of the SDWA to add the requirement of quarterly sampling for Haloacetic Acids in the distribution system. Monitoring will take place and on January 1, 2020 this parameter will be added to Schedule 2 of the Ontario Water Quality Standards. This Disinfection By-Product will have a Maximum Acceptable Concentration of 80 based on a running annual average of quarterly results calculated for each calendar quarter. The 2017 update also included reductions in the standards for carbon tetrachloride, benzene and vinyl chloride effective January 1, Improvements in analytical methods allow chemicals in drinking water samples to be detected in lower amounts (uranium, selenium and arsenic). For the chemicals with

4 improved methods, there is no apparent change in water quality, only a change of analytical method. All results were well below the Ontario Water Standards Maximumm Acceptable Concentrations. The Province of Ontarioo sets the level of quality that is to be maintained for all Water in Ontario and the quality standards are defined in the legislation O. Reg.169/03. If you have any questions or would like copies of thiss report please call the Region of Waterlooo 24-hour Call Centre at Sincerely, Olga Vrentzos, B.Sc. Manager, Operations & Maintenance Water Services

The 6 wells pump into the Middleton Reservoir and Pumping Station. The capacity of the reservoirr is one million imperial gallons (about 4,500 cubic meters). In 2013, construction of an Advanced Oxidation Process (AOP) building was completed. The AOP system is used to treat trichloroethylene and consists of 4 Ultra Violet (UV) units and an oxidant system consisting of solution tanks completee with spilll containment and metering pumps. Primary disinfection for all the wells is achieved by the UV disinfection units. Disinfection is also achieved by the use of a sodium hypochlorite system consisting of solution tanks complete with spill containment and protection and metering pumps dispensing commercial 12% sodium hypochlorite solution. The raw water is chlorinated prior to entering the UV units and reservoir, and levels are monitored byy continuouss chlorine analyzers. There is also the ability to add additional sodium hypochlorite at the discharge of the reservoir as required. Continuous analyzers monitor the levels of chlorine, turbidity and UV dosage prior to the water being discharged. The analyzers are connected with the Mannheim Water Treatment Plant SCADA system which is monitored by an operator 24 hours per day.

These wells pump directly into Turnbull Treatmentt Plant and Pumping Station. The Turnbull WTP has three open filters filled with manganese greensand and anthracite coal. The welll water is treated with sodium hypochlorite afterr entering the raw reservoir. The sodium hypochlorite system consists of solution tanks complete with spilll containmen and protection and metering pumps dispensing commercial 12% sodium hypochlorite solution. The sodium hypochlorite system is located in the main building at Turnbull Treatment Plant and Pumping Station. The sodium hypochlorite has two purposes, iron and manganese oxidation and disinfection. After filtration, the water is stored in a clearwell. This clearwell iss divided into two equal cells with a combined total volume of 92,000 imperial gallons (about 420 cubic meters). From there, the treated water is discharged into the Turnbull Reservoir, with a total volume of 5 million imperial gallons (about 22.8 ML) ). Continuous analyzers monitor the levels of chlorine and turbidity prior to the water being discharged. The analyzers are connected with the Mannheim Water Treatment Plant SCADA system which is monitored by an operator 24 hours per day. This site has no emergency standby power available.

These wells pump directly into the Greenbrook Treatment Plant and Pumping Station. Iron and manganesee removal is achieved through the use of threee pressure filters. Following filtration, treatment for 1,4-dioxane is accomplished by an advanced oxidation process using 50% hydrogen peroxide and Ultraviolet (UV) irradiation. Treated water from the UV reactors proceeds through upflow Granular Activated Carbon (GAC) contactors before being transferred to 2 storage reservoirs with capacities of 2 million gallons (approximately 10,000 cubic metres) and 500,000 gallons (approximately 2400 cubic metres). Disinfection is achieved through Ultraviolet (UV) irradiation and by the use of a sodium hypochlorite system consisting of a solution tank complete with spill containment and protection and a metering pump dispensing commercial 12% sodium hypochlorite solution. 20% ammonium sulphate is added to the water at the discharge header off the pumping station prior to the water leaving the station. The purpose of the ammonium sulphate is to convert free chlorine to the combined form, creating a more stable distributionn disinfectant. Continuous analyzers monitor the levels of chlorine, turbidity, UVT and UV dosage prior to the water being discharged. The analyzers are connected with the Mannheim Water Treatment Plant SCADA system which is monitored by an operator 24 hours per day. There is no emergency standby power at this site.

The raw water entering the WTP is treated with coagulation, flocculation, sedimentation, ozonation and filtration. Immediately after filtration, the water is disinfected prior to entering the clearwells/reservoirs. There are two clearwells/reservoirss that have a combined total usable volume of ML. Disinfection is achieved throughh ozonation, ultraviolet (UV) irradiation followed by chlorination via a gas chlorination system. Continuous analyzers monitor the levels of ozone, chlorine, turbidity, UVT and UV dosage prior to the water being discharged. The analyzers are connected with the Mannheim Water Treatment Plant SCADA system which is monitored by an operator 24 hours per day. The water from the Mannheim Aquifer Storage and Recovery Facilities (ASR1, ASR2, ASR3, ASR4, RCW1 and RCW2) can be mixed with the treated water and then stored in the clearwells/reservoirs. This water is then directed to thee Mannheim Pumping Station Reservoir, where it blends with seven other ground water wells (K91, K92, K93, K94, K21, K25, and K29). Treated water from the Mannheim Village wells (K22A, K23, K24 and K26) and Shingletown wells (K50 and K51) can also indirectly supply the Mannheim Pumping Station Reservoir. This reservoirr has a total storage capacity of ML. Prior to the treated water being pumped into the distribution system, anhydrous ammoniaa is injected to convert free chlorine to the combined form, creating a more stable distribution disinfectant. As a backup to the anhydrous ammonia system, there is the capability to inject 20% liquid ammonium sulphate. This facility has emergency standby power available. List all water treatment chemicals used over this reporting period Chlorine gas, 12% sodium hypochlorite, anhydrous ammonia, polyaluminum chloride (coagulant), polyelectrolyte (filter aid), liquid oxygen n (LOX), ozone, ultraviolet (UV) irradiation, calcium thiosulphate, granularr activated carbon, 20% ammonium sulphate.

These wells pump directly into the Parkway Reservoir and Pumping Station. The Parkway Reservoir has a capacity of three million imperial gallons (14,000 cubic meters). Disinfection is achieved by the use of a sodium hypochlorite system consisting of a solution tank completee with spill containmen and protection and a metering pump dispensing commercial 12% sodium hypochlorite solution. Ammonium sulphate is added to the water at the discharge header of the pumping station prior to the water leaving the station. The purpose of the ammonium sulphate is to convert free chlorine to the combined form, creating a more stable distribution disinfectant. These chemical systems are located at Parkway Reservoir and Pumping Station. Continuous analyzers monitor the levels of chlorine and turbidity prior to the water being discharged. The analyzers are connected with the Mannheim Water Treatment Plant SCADA system which is monitored by an operator 24 hours per day. This site has no emergency standby power available on site.

Thesee wells pumpp directly into the Strange Street Reservoir and Pumping Station. The Strange Street Standpipe has a capacity of 940,000 imperial gallons (4.27 ML). The water is disinfected prior to entering the reservoir. Disinfection is achieved by the use of sodium hypochlorite systemss consisting of solution tanks completee with spill containment and protection and metering pumpss dispensing commercial 12% sodium hypochlorite solution, located at wells K10A, K11A, K13 and K18/K19 prior to entering the reservoir. Ammonium sulphate is addedd to the water at the discharge header of the pumping station prior to the water leaving the station. The purpose of the ammonium sulphate is convert free chlorine to the combined form, creating a more stable distribution disinfectant. Continuous analyzers monitor the levels of chlorine and turbidity prior to the water being discharged. The analyzers are connected with the Mannheim Water Treatment Plant SCADA system which is monitored by an operator 24 hours per day. This site has no emergency standby power available on site.

These wells pump directly to the Erb Street Reservoir. The Erb Street Reservoir has a capacity of four million imperial gallons (18,000 cubic meters). Disinfection for each of the wells is achieved by the use of sodium hypochlorite systems consisting of solution tanks complete with spill containment and protection and metering pumps dispensing commercial 12% sodium hypochlorite solution. Ammonium sulphate is addedd to the water at the inlet of the Erb Street Reservoir. The purpose of the ammoniumm sulphate is to convert free chlorine to the combined form, creating a more stable distribution disinfectant. Continuous analyzers monitor the levels of chlorine and turbidity prior to the water being discharged. The analyzers are connected with the Mannheim Water Treatment Plant SCADA system which is monitored 24 hours per day. Theree is no emergency standby power available at this site.

The total storage capacity of the stand pipe is 5,061 cubic meters. The treatment facility uses four dual media pressure filters, filled with catalytic media and anthracite media, for removal off iron. Water that is not immediately required is stored in the above ground stand pipe. Disinfection is achieved by the use of a sodium hypochlorite system consisting of a solution tank completee with spill containment and protection and metering pumpss dispensing commercial 12% sodium hypochlorite solution. The sodium hypochlorite e is also used as an oxidizing agent prior to filtration. Before the treated water is discharged from the treatment plant into the distribution system, it passes through a two-celled reservoir with a 2500 cubic metre capacity. Continuous analyzers monitor the levels of chlorine and turbidity prior to the water being discharged. The analyzers are connected with the Mannheim Water Treatment Plant SCADA system which is monitored by an operator 24 hours per day.
