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: (a) list the requirements of the Act, the regulations, the system’s approval and any order 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: 1. A summary of the quantities and flow rates of the water supplied during the period covered by the report…. 10 - 1 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, 2015: rd A Ministry of Environment (MOE) inspection was completed from November 23 th to November 27, 2015 for the Kitchener System and an annual inspection report rd was prepared on January 23, 2016. The report did not identify any non- compliances for the system. The 2016 inspection has not been scheduled. There were 24 Adverse Water Quality Incidents (AWQI’s) reported in this time Table 1 period (see attached ), of which 16 were due to a result of total coliform in the temporary watermains. Temporary watermains are particularly sensitive as they are above ground systems influenced by the water heating up in warmer temperatures. This may cause the potential for bacteriological growth. Due to the sensitive nature, all temporary watermains are sampled on an increased schedule (every 2 weeks at multiple locations). The additional challenge with temporary watermains is the sample port is located outside and subject to unsanitary conditions. Although efforts are made with the design of the ports to prevent contamination, sampling is not completed under ideal sanitary circumstances. The general nature of reconstruction projects often leads to “false” positives, where the results received are more reflective of what is on the sampling 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. 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 types of strains of coliform bacteria. Most are harmless and do not cause illness. Coliform bacteria are used as an “indicator organism” to assess 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, we resample using a different technique which provides a number of total coliforms for us to analyze in consultation with Public Health and the Ministry of Environment. Based on a risk assessment of a number of factors including: the coliform count, chlorine residuals, upstream/downstream coliform counts, the requirement for a boil water advisory is determined. There were ten (9) incidences of the presence of total coliform in a single temporary watermain on King St S. The continued presence of the total coliform on this temporary watermain resulted in a precautionary Boil Water Advisory. There were three (3) Boil Water Advisories in total for 2014. The other two (2) were precautionary due to the potential contamination with sewage during emergency repairs (resamples were clear). Dead end watermain flushing is a proactive approach to increase the levels of chlorine in the distribution system. The water is initially disinfected (primary 10 - 2 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. Lead testing sampling programs were completed in March/April and September/ October 2015. There were no lead exceedances in the distribution system. There were seven (7) residential plumbing exceedances (>10 µg/L) during the year. The City is not obligated to complete any additional corrective actions other than reporting, unless directed by the Medical Officer of Health for the residential plumbing exceedances. A summary of the quantities of the water supplied by the Regional Municipality of Table Waterloo during the period covered by the report is noted on the attached 2 . A decrease in the variance in the month of June was due to a slightly cooler than normal month. ALIGNMENT WITH CITY OF KITCHENER STRATEGIC PLAN: The Annual Summary Water Report relates to the Foundation Plan – Efficient and Effective Government – Communications goal to “Proactively communicate with Kitchener residents in an effort to share information; educate and engage the public, and promote enterprises, programs and services; to create a corporate culture where internal communications is a priority for all City” FINANCIAL IMPLICATIONS: None. COMMUNITY ENGAGEMENT: INFORM – This report has been posted to the City’s website with the agenda in advance of the council / committee meeting. The Ministry of the Environment and the Regional Municipality of Waterloo’s Community Department of Health have been informed of any adverse conditions within the system. Under Schedule 22 of O.Reg. 170/03, the City of Kitchener is required to provide a copy of their Summary Report to each Municipality to which it supplies water, namely the Township of Woolwich and the City of Waterloo. A similar report - The City of Kitchener Water Distribution Annual Report is provided electronically on the Kitchener Utilities website, and hard copy is available at the Kitchener Operations Facility (131 Goodrich Drive). Residents are informed via a newspaper ad.
