Home My WebLink AboutINS-2021-1 - Summary Water Report - 2020Staff Report Infrastructure Services Department REPORT TO: Community & Infrastructure Services DATE OF MEETING: March 8, 2021 www.kitchenerca SUBMITTED BY: St. Louis, Greg, Director, Gas & Water Utilities, 519-741-2600 ext.4538 PREPARED BY: Mick, Angela, Manager, Quality Management and Water Programs, 519-741-2600 ext. 4408 WARD(S) INVOLVED: All DATE OF REPORT: January 29, 2021 REPORT NO.: INS -2021-1 SUBJECT: Summary Water Report - 2020 RECOMMENDATION: THAT the 2020 City of Kitchener Summary Drinking Water Report be received for information as required by O.Reg. 170/03 Schedule 22 of the Safe Drinking Water Act, AND FURTHER THAT the City of Kitchener provide a copy of the Summary Drinking Water report to the Township of Woolwich and the City of Waterloo as required by Schedule 22 of O.Reg. 170/03. REPORT HIGHLIGHTS: The key finding of this report is that the City of Kitchener is in compliance with regulatory water sampling requirements for the reporting period of January 1, 2020 to December 31, 2020. The strategic plan alignment is through the delivery of core services. There are no financial implications of this report BACKGROUND: As outlined in Schedule 22 of the Drinking Water Systems Regulation (0.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. *** This information is available in accessible formats upon request. *** Please call 519-741-2345 or TTY 1-866-969-9994 for assistance. 70 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, 2020: • 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 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 Waterloo's water quality report is available on their website. • The Ministry of Environment, Conservation and Parks (MECP) completed an unannounced annual inspection on July 30, 2020 which covered January 1, 2020 to June 30, 2020. There were no non -compliances found. • There were 4,418 chlorine residual samples taken and 2,253 bacteriological samples taken within the distribution system. Of these, there were 42 Adverse Water Quality Incidents (AWQI's) reported in this time period (see attached Table 1) and all resamples were clear. • 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. • Of the low chlorine AWQIs (13 total) o Eight were in areas of new subdivisions with no houses yet built. Along with dead end water mains, KU proactively flushes areas with new water mains until there are homes built and water is being used. o 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. Of the total coliform AWQIs (22 total) 0 21 were at temporary sampling locations. o 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 71 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 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. Additional communications efforts to contractors regarding the importance of maintain the sampling ports in a sanitary manner will be made over the 2021 construction season. o 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 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. o 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. • Six self imposed boil watery advisory were implemented —four due to potential sewer contamination as a result of private side water service damage, one due to potential contamination from sewer damage during a watermain break and one at a temporary main. • Two high sodium AWQIs were reported, both at the same location. Correction actions, other than reporting, are not required. Sodium is a common element in the natural environment and is often found in drinking water. It can occur naturally or be the result of nearby road salt applications. Sodium in drinking water is not a health concern for most people but may be an issue for someone with hypertension, congestive heart failure or on a sodium -reduced diet. Those on sodium restricted diet should consult their physician. Public Health has an information document regarding sodium in drinking water. • The Region of Waterloo's Strange Street Water Pumping station was offline starting in fall 2019 for installation of a manganese treatment system, which is anticipated to decrease discoloured water issues in the surrounding area. The station upgrades should be complete by 2022. A summary of the quantities of the water supplied by the Regional Municipality of Waterloo during the period covered by the report is noted on the attached Table 2. Water volumes increased in 2020 likely due to a combination of hot weather and more customer use throughout COVID (e.g. gardens). 72 Table 1 — Adverse Water Quality Incident Summary — January 1 to December 31, 2020 # Adverse AWQI Date AWQI # Site Name Site Results/Notes Type (verbal) Location 1 Self imposed March 6 149713 Hearth Cres & 45 Units Potential sewage BWA Hahn Place contamination Samples were clear BWA from March 6- 8 2 Self imposed March 18 149762 7 Pipers Green 1 Unit Water serviced BWA Crt damaged by contractor — potential sewage contamination Samples were clear BWA from March 18-21 3 Low chlorine April 17 149884 Hydrant 10864 513 Free=0.01 mg/L, Beckview Total=0.07mg/L Cres New development 4 High sodium May 8 149957 KID 116 19 Forest Sodium=130mg/L Creek Dr 5 Low chlorine May 11 149961 Hydrant 11185 Otterbein & Free=0.03mg/L Lackner Total=0.03mg/L New development 6 High sodium May 12 149969 KID 116 19 Forest Sodium = 141 mg/L.
