3 Reporting Requirements Ontario Regulation 170/03 requires that municipalities prepare a Summary Report for their drinking-water system for the preceding calendar year and submit it to the members of the Municipal Council by March 31 of each year. This report, presented to Municipal Council s Civic Works Committee on February 7, 2017 fulfills that requirement. O. Reg 170/03 also requires the preparation of an Annual Report on the operation of the drinking-water system to be made available to members of the public. Before February 24, 2017, a copy of the 2016 Annual Report and Summary Report for the City of London s water works will be provided to the local office of the Ministry of the Environment and Climate Change (MOECC) as a courtesy for information purposes. The Elgin-Middlesex Pumping Station (EMPS) is jointly owned by the St. Thomas Secondary Water Supply System, the Aylmer Secondary Water Supply System, and the City of London. EMPS is operated by the Ontario Clean Water Agency (OCWA). The Annual Report for the EMPS (London portion) was not yet available at the time of writing this report, and will be provided to members of Council under separate memo prior to the reporting deadline of February 28, Ministry of the Environment and Climate Change Annual Inspection (MOECC) MOECC inspections can be in the form of comprehensive detailed inspections, or less intensive focused inspections. The MOECC selected London s Water Distribution System for a focused inspection in The MOECC inspection, conducted on December 7, 2016, included staff interviews and facility inspections, as well as a review of operating procedures, water analysis reports, operational records, and staff certification and training records. On January 10, 2017, the MOECC issued the City of London Water Distribution System Inspection Report. The report summarizes the inspection findings, and lists any incidents of non-compliance with regulatory requirements. The City of London received a Final Inspection Rating of 96.05% for A full report on this MOECC Inspection is being presented to the Civic Works Committee on February 7, Water Operations Staff Complement and Training In 2016, the distribution system was operated and maintained by four (4) Water Supply staff, thirty-one (31) Operations and Maintenance staff, three (3) Waterworks Inspectors, eight (8) Meter Shop staff, five (5) Waterworks Supervisors, two (2) Technologists, two (2) Administrative staff, and four (4) Management staff. This complement does not include senior administrative staff of the Water Service Area. The majority of the City of London s operational and maintenance staff are based at the A.J.

4 Centre, located at 663 Bathurst Street. Water Supply staff are based out of the London Hydro building at 111 Horton Street. All employees with Drinking Water Operator Certificates receive a minimum of 14 hours of Director-approved training and an additional 36 hours of practical, on-the-job training each year, as mandated by Regulation. Water Budget The approved operating and capital budgets represent financial sustainability for Londoners, whereby annual rate increases are approximately the average of the Consumer Price Index (CPI) and the n-residential Building Construction Price Index (NRBCPI). The water operating and capital budgets support four core business objectives: Compliance Financial Management Customer Service Best Management Practices The total Water budget for 2016 was $73.8 million, which includes long term infrastructure renewal and replacement plans. The Water Budget helps maintain London s Advantage of a safe, clean and secure water supply. The Water Service Area remains proactive in initiatives to ensure that this service continues to meet the demands and expectations of customers. Existing infrastructure requires ongoing renewal (replacement and rehabilitation) activities to manage the infrastructure gap, ensuring that future generations are not faced with a water system that is failing, unreliable, and expensive to maintain. Emerging Trends in Water Treatment & Regulations Water Treatment: The City of London purchases its treated drinking water from the Joint Boards of Management (Lake Huron and Elgin Area Primary Water Supply Systems). The Joint Boards of Management, through the Regional Water Supply Division, stay abreast of emerging trends in water treatment and monitor upcoming regulation changes. Current areas of interest include Microbiological (E. coli and Total Coliform), Disinfection By-Products (Trihalomethanes -THMs, Haloacetic Acids HAAs), Lead and Copper, and Emerging Pathogens and Chemicals. Currently, there are no water quality concerns requiring process modification at the Regional Water Supply treatment facilities. Emerging contaminants including pharmaceuticals and personal care products (PPCP s), endocrine disruptors (EDC s), and microplastics will be the focus of much research in the coming decades. At this time, there is no evidence to suggest that the Joint Board of Management should conduct further investigations into the implementation of advanced or enhanced treatment processes. For further information on emerging trends in water treatment and Regulations, refer to the Lake Huron and Elgin Area Water Supply Systems Master Plans, which can be found at Compliance Summary Report Corporation of the City of London Page 4 of 64

5 Sampling & Water Quality Monitoring In 2016, the MOECC required large municipal drinking water systems to test for 70 different organic, inorganic and chemical parameters. The City of London s water sampling regime includes monthly testing for microbiological indicators and chlorine residuals from 57 standard locations across the City, as well as more than 2,800 random grab samples. Analysis is also performed for up to 112 parameters, including organics, inorganics, chemicals, pesticides and metals at 13 standard locations around the City. In addition, 764 samples were analysed from London s stand-by wells. This level of testing far exceeds the MOECC s minimum sampling requirements. London also has 10 locations throughout the City where continuous in-line sampling of chlorine residual and ph is monitored. Staff also perform approximately 4,000 additional chlorine tests each year related to construction and maintenance activities. All of these efforts help ensure that the water within the distribution system is always of high quality Water Quality Sampling Summary Ontario Maximum Lab's Method Measured MAC Parameter Acceptable Concentration (MAC) Units Detection Limit (MDL) Concentrations Exceedance (Y/N) 2016 REGULATED INORGANICS Antimony 6 ug/l Arsenic 25 ug/l Barium 1000 ug/l Boron 5000 ug/l Cadmium 5 ug/l Chromium 50 ug/l Fluoride 1.5 mg/l Free Chlorine Residual 4.0 mg/l N/A Mercury 1 ug/l 0.01 <MDL Selenium 10 ug/l Sodium *20 mg/l Uranium 20 ug/l Ontario Maximum Lab's Method Measured MAC Parameter Acceptable Concentration (MAC) Units Detection Limit (MDL) Concentrations Exceedance (Y/N) 2016 REGULATED ORGANICS Atrazine -- ug/l Atrazine + N-dealkylated metabolites 5 ug/l De-ethylated Atrazine -- ug/l 0.01 <MDL Azinphos-methyl 20 ug/l 0.05 <MDL Benzene 5 ug/l 0.32 <MDL Benzo(a)pyrene 0.01 ug/l <MDL Bromoxynil 5 ug/l 0.33 <MDL Carbaryl 90 ug/l 0.05 <MDL Carbofuran 90 ug/l 0.01 <MDL Carbon tetrachloride 5 ug/l 0.16 <MDL 2016 Compliance Summary Report Corporation of the City of London Page 5 of 64

Five (5) involved the detection of Total Coliform bacteria (ranging from 1 to 87 cfu/100 ml). One (1) was due to results of Data Overgrown with n-target Bacteria. In each case, staff implemented the mandatory adverse response procedure, which included notifying the MOECC and the Middlesex-London Health Unit, and immediately re-sampling at each location. The re-sample results revealed no adverse indicators. In all instances it is highly unlikely that there were actual water quality issues at these sites, as the six adverse samples were identified as having free chlorine residuals which were well above the minimum acceptable level at the time of the sampling (ranging between 0.34 to 0.82 mg/l). E. coli and Coliform bacteria cannot survive in chlorinated water; therefore, it is suspected that post-sampling contamination occurred. The resampling results support this conclusion. The microbiological testing procedure is extremely sensitive; accidental sample contamination can occur through operator or laboratory error, despite the specific procedures and precautions being adhered to while processing samples. System Statistics and Major Events During the period from January 1, 2016 through to December 31, 2016 a total of 46,639,508,000 litres of water were purchased, at a cost of more than $23,500,000, from the Joint Water Boards and subsequently pumped into London via the Arva Pumping Station and EMPS. Average day demand was 127,000,000 litres. Peak day consumption of 179,631,000 litres occurred on July 5, A summary of system pumpage can be found starting on page 52.
