Groundwater Quality

The Provincial Groundwater Monitoring Network (PGMN) is a partnership program between the Ontario Ministry of the Environment, Conservation and Parks and the province’s Conservation Authorities, as well as some municipalities in areas not covered by a Conservation Authority. There are almost 400 wells monitored across the province. The PGMN program began in 2000 and is designed to monitor ambient groundwater level and chemistry conditions across Ontario.  Toronto and Region Conservation Authority (TRCA) is responsible for maintaining the digital telemetry systems at 21 monitoring wells in our jurisdiction, collecting water level data and arranging for chemical analyses of water quality samples at dedicated wells.
