Owners of Municipal Drinking Water Systems are mandated by the Safe Drinking Water Act (O. Reg. 170/03) to conduct lead sampling on their systems. The City of Kawartha Lakes conducts sampling for pH and Alkalinity (precursors for lead) twice per year (once in the summer and once in the winter), and conducts residential lead sampling (from residential homes throughout the City) once every three years. Sampling locations for pH and Alkalinity are chosen from areas most commonly used for providing water for human consumption throughout the City. Once sampling is complete, and analyzed by the lab, results are sent to the MOECC (Ministry of Environment and Climate Change.)
Homes built before 1950 are more likely to have water service connections (pipe) made of lead and since scientific research and regulatory reviews have illustrated that lead exposure can be harmful, it is important that home owners report any existing lead connections. While the municipal water supply in The City of Kawartha Lakes is essentially lead-free and the City continues to work to replace any municipality-owned lead service pipes, homeowners who are concerned can be vigilant and check their pipes. To easily identify if a pipe is made of lead, scratch the pipe with a key or coin. If the pipe is lead, the area scratched will turn a bright silver colour. Should this occur, please have a licenced plumber validate that the pipe is indeed lead and contact the Water and Wastewater Department at (705) 324 9411 ext. 1121.
