*In Ontario chloride concentrations (Cl<sup>-</sup>) are measured monthly under the Provincial Water Quality Monitoring Network (PWQMN)<ref>Ontario Government. 2021. Provincial (Stream) Water Quality Monitoring Network. https://data.ontario.ca/dataset/provincial-stream-water-quality-monitoring-network (Accessed: 25 Mar., 2022)</ref>. Concentrations in the mouth of the Don River has showcased levels three times that of the Canadian Water Quality Guidance (CWQG) for long-term chronic effects to the environment and species.

*Although the PWQMN has been an excellent tool for following the long-term trends of median concentration levels in the province's watersheds the infrequency of sampling will at times miss peak and extreme values and outliers that result in excessive salt and chloride loadings in key areas with species at risk, etc.

*As a result, TRCA, along with its partners began a monitoring project at the mouths of the major tributaries within the GTA using high-frequency sensors, which make readings ever 15 mins.
