(b) for each failure referred to in (a), describe the measures that were taken to correct the <br />failure. <br />The report must also include a summary of the quantities and flow rates of the water supplied <br />during the period covered by the report. <br />REPORT: <br />The following matters are reported to Council in accordance with the requirements of the <br />Safe Drinking Water Act, for the period from January 1 to December 31, 2021: <br />• The Kitchener Distribution System is part of an Integrated Urban System, meaning <br />the Regional Municipality of Waterloo is responsible for water treatment and the <br />development and operation of a trunk water network to distribute treated water to <br />Kitchener, Cambridge, Waterloo, Woolwich, and Wilmot. The Region provides annual <br />summaries for each supply and the information is available on their website with a <br />link from the Kitchener Utilities (KU) website. Reports from the connected systems <br />have been or will be received. <br />• A portion of Kitchener (River Ridge area) is supplied by the City of Waterloo. <br />Kitchener supplies water to a small section of Waterloo (Ira Needles area) and water <br />travels through the Kitchener distribution system to Breslau. The City of Waterloo's <br />water quality report is available on their website. <br />• The Ministry of Environment, Conservation and Parks (MECP) completed an annual <br />inspection on June 22, 2021, which covered June 30, 2020 to June 22, 2021. There <br />were no non -compliances found. <br />• There were 3,612 chlorine residual samples taken and 1,760 bacteriological samples <br />taken within the distribution system. Of these, there were 21 Adverse Water Quality <br />Incidents (AWQI's) reported in this time period (see Table 1) and all resamples were <br />clear. The City was on a ministry approved reduced sampling schedule for a portion <br />of 2021 due to COVID access restrictions on many sampling sites. <br />• An AWQI does not necessarily mean that the water is a risk to the customer. It means <br />that a potential problem has been identified and corrective actions must be taken to <br />resolve the problem. City staff work with ministry staff and the local public health unit <br />to resolve the issue, which generally includes resampling. <br />• Low chlorine AWQIs can occur in areas of new subdivisions with no houses yet built. <br />Along with dead end watermains, KU proactively flushes areas with new watermains <br />until there are homes built and water is being used. <br />• Dead end watermain and new development flushing is a proactive approach to <br />increase the levels of chlorine in the distribution system. The water is initially <br />disinfected (primary disinfection) at the treatment plant and sufficient chlorine is <br />added to protect the water from microbiological contamination as it travels through <br />the pipes in the distribution system (secondary disinfection). Low chlorine does not <br />pose a threat to human health; to have an impact to human health, there must be <br />microbiological contamination and no, or extremely low, chlorine. <br />• Of the total coliform AWQIs (17 total): <br />o Eight (8) were at temporary sampling locations within reconstruction projects. <br />Temporary watermains are particularly sensitive as they are above ground <br />systems influenced by the water heating up in warmer temperatures. This may <br />increase the potential for bacteriological growth. Warmer weather seems to <br />increase the incidences of Total Coliform. The additional challenge with <br />Page 4 of 132 <br />
