In 2014, Newmarket conducted their lead sampling program in compliance with Schedule 15.1 of O. Reg. 170/03 of the Safe Drinking Water Act. Sixteen (16) samples were taken and submitted to the York-Durham Regional Environmental Laboratory for analysis. Sample results ranged from between 0.0001mg/L-0.0006mg/L for distribution system samples. The provincial standard for lead content in water is 0.01 milligrams/litre.
Due to sufficient evidence indicating that lead is not leaching from infrastructure in the Newmarket WDS, combined with a significant decline in volunteers for residential samples, the Corporation of the Town of Newmarket, on April 20, 2012, submitted a request for Regulatory Relief from Lead Sampling Requirements.
The application for relief was approved by the Ontario Ministry of the Environment, with the below table updated to illustrate the Newmarket WDS's new regulatory requirements (effective until October 15, 2016).
