TRCA 2020 Water Quality Data from Regional ...
The data represent stream water quality conditions sampled throughout TRCA's Regional Watershed Monitoring Program.
"Dataset contains water quality results from samples collected throughout the TRCA's 9 watersheds for the year specified in the Dataset Name. Data includes station name and location, sample date, water quality parameter name and the final value returned from the laboratory conducting the analysis. Units of measure and the Agency/Lab providing the analysis is also included.
Monthly samples were collected using in-stream “grab” techniques following the Provincial Water Quality Monitoring Network (PWQMN) protocol (Ministry of the Environment, Conservation and Parks 2020) and also included in-situ measurements (e.g. water temperature, pH and dissolved oxygen) collected using a hand-held water quality multi-probe (YSI or ProDSS). Water quality samples were collected throughout the year, typically in the third week of each month, irrespective of precipitation. Samples from the 13 stations that are part of the PWQMN partnership were submitted to the MECP Rexdale Laboratory. The remaining samples from stations or months not included in the PWQMN (e.g. December to March) were submitted to the City of Toronto Dee Avenue Laboratory in order to augment water quality data from these stations, and to maintain a year-round dataset."
