REPORT HIGHLIGHTS: The key finding of this report is that the City of Kitchener is in compliance with regulatory water sampling requirements of the reporting period of January 1, 2022 to December 31, 2022. There are no financial implications of this report. The report supports the delivery of core services. BACKGROUND: As outlined in Schedule 22 of the Drinking Water Systems Regulation (O.Reg.170/03) of the Safe Drinking Water Act, 2002, a Summary Report is to be prepared and given to the members of the municipal council. The following information is required to be included in this report: that the system failed to meet at any time during the period covered by the report and specify the duration of the failures; and (b) for each failure referred to in (a), describe the measures that were taken to correct the failure. The report must also include a summary of the quantities and flow rates of the water supplied during the period covered by the report. REPORT: The following matters are reported to Council in accordance with the requirements of the Safe Drinking Water Act, for the period from January 1 to December 31, 2022: The Kitchener Distribution System is part of an Integrated Urban System, meaning the Regional Municipality of Waterloo is responsible for water treatment and the development and operation of a trunk water network to distribute treated water to Kitchener, Cambridge, Waterloo, Woolwich, and Wilmot. The Region provides annual summaries for each supply and the information is available on their website with a link from the Kitchener Utilities (KU) website. Reports from the connected systems have been or will be received. A portion of Kitchener (River Ridge area) is supplied by the City of Waterloo. Kitchener supplies water to a small section of Waterloo (Ira Needles area) and water travels through the Kitchener distribution system to Breslau. The City of website. The Ministry of Environment, Conservation and Parks (MECP) completed an annual inspection on June 23, 2022, which covered June 23, 2021 to June 23, 2022. There were no non-compliances found. There were 3,943 chlorine residual samples taken and 2,311 bacteriological samples taken within the distribution system. Of these, there were 15 Adverse Table 1) and all resamples were clear. The Lead Sampling program was minimal due to a pandemic related sampling relief, however all lead samples taken were below the limits. Summary of AWQIs An AWQI does not necessarily mean that the water is a risk to the customer. It means that a potential problem has been identified and corrective actions must be taken to resolve the problem. City staff work with ministry staff and the local public health unit to resolve the issue, which generally includes resampling. Low Chlorine Residual AWQIs Low chlorine AWQIs can occur in areas of new subdivisions with no houses yet built. Along with dead end watermains, KU proactively flushes areas with new watermains until there are homes built and water is being used. Dead end watermain and new development flushing is a proactive approach to increase the levels of chlorine in the distribution system. The water is initially disinfected (primary disinfection) at the treatment plant and sufficient chlorine is added to protect the water from microbiological contamination as it travels through the pipes in the distribution system (secondary disinfection). Low chlorine does not pose a threat to human health; to have an impact to human health, there must be microbiological contamination and no, or extremely low, chlorine. Bacteriological AWQIs The presence of total coliform on a test does not necessarily mean the water is unsafe to drink. Coliform bacteria can be found in many different environments. There are several different strains of coliform bacteria. Most are harmless and do the possibility of other disease-causing organisms, and their detection would prompt further investigation and/or corrective action. It is different than E.coli, which is a bacteria only associated with human or animal faecal matter. When total coliform is found, a resample is done using a different technique, which provides a number of total coliforms to analyze in consultation with Public Health and the MECP. Based on a risk assessment of a number of factors including the coliform count, chlorine residuals, and upstream/downstream coliform counts, the requirement for a boil water advisory is determined. Four (4) total coliform AWQIs were at temporary sampling locations within reconstruction projects. Temporary watermains are particularly sensitive as they are above ground systems influenced by the water heating up in warmer temperatures. This may increase the potential for bacteriological growth. Warmer weather seems to increase the incidences of Total Coliform. The additional challenge with temporary watermains is the sample port is located outside and subject to unsanitary conditions. Many contractors remove the sampling ports when not in use because they are subject to vandalism/theft. These ports need to be maintained in a sanitary condition between uses. The general nature of reconstruction p tap, rather than what is in the water. Every positive result is reportable, and resampling must occur in accordance with regulations. When the resamples are clear, it is an indication that the issue was with the sampling port, not in the water. Six (6) Total Coliform AWQIs were related to flushing within new development areas. There was one Boil Water Advisory as a result of a positive E.Coli sample at a community centre. Resamples showed the area was free of contamination Drinking Water Advisory There was one Drinking Water Advisory on two addresses related to manufacture supplied fittings with non-potable grease. The fittings were removed from the system and will no longer be used. Sampling completed before and after the fittings were removed both showed oils and grease and semi-volatiles below lab detection limits. No further action was required.
