The park monitors water quality of streams and ponds (lakes) on a triennial cycle, reporting on total organic carbon, acidity, phosphorus, nitrogen, dissolved oxygen, turbidity, and Chlorophyll A. These metrics are compiled into a water quality index (WQI) that summarizes overall water quality.
The Lake Simcoe lake monitoring program provides measurements of chemical and physical water quality limits such as total phosphorus, nitrogen, chlorophyll a, pH, alkalinity, conductivity, dissolved organic and inorganic carbon, silica, other ions, water transparency, temperature and dissolved oxygen. Samples are collected biweekly during the spring, summer and fall. *[pH]: potential of hydrogen
Many processes and functions in wetlands are driven by water quality, this measure can therefore determine the composition and health of wetland species. Point Pelee National Park collects several parameters to monitor water quality in the park wetlands such as turbidity, total suspended solids, total phosphorus, total nitrogen, and specific conductivity.
Every five years, water quality is assessed in 32 inland lakes that are greater than 8 hectares in surface area. Samples are collected via helicopter and three key stressors (acidification, eutrophication and metal loading) are assessed using nine parameters [pH, aluminum, calcium, total nitrogen, total phosphorus, dissolved oxygen concentration, iron (Fe), cadmium (Cd) and lead (Pb)]. YSI measurements and Secchi disk measurements are also taken. Samples are sent to the National Laboratory for Environmental Testing (NLET), Burlington, ON, to test for metals and to Natural Resources Canada, Sault Ste.
The Water Quality Index (WQI), developed by the Canadian Council of Ministers of Environment (CCME) is used to assess the water quality of Pukaskwa’s rivers and streams. Three key stressors (acidification, eutrophication and metal loading) are assessed using nine parameters [pH, aluminum, calcium, total nitrogen, total phosphorus, dissolved oxygen concentration, iron (Fe), cadmium (Cd) and lead (Pb)]. Water samples are collected three times a year (spring, summer and fall) from each sampling site (White River, Willow River, Oiseau Creek, White Gravel River, North Swallow River, Swallow, Cascade River, Tagouche Creek and Imogene Creek). Samples are sent to the National Laboratory for Environmental Testing (NLET), Burlington, ON, to test for metals and to Natural Resources Canada, Sault Ste.

Water quality of tributaries in the Athabasca River oil sands region is heavily influenced by the presence of the underlying Cretaceous bedrock, which is comprised of shale, sandstone and limestone. The waters are moderately hard (average alkalinity of 114 mg l-1 CaCO3) because of their mineral content, particularly magnesium (average 8.62 mg l-1), calcium (average 28.06 mg l-1) and bicarbonate (138.53 mg l-1). This mineral content results in an average conductivity of 245 +/- 4 µS cm-1 and total dissolved solids concentration of 140 +/- 2 ppm. Concentrations of nitrogen and phosphorus (indicators of nutrient status) are typically low to moderate, averaging 0.14 mg l-1 total phosphorus, 0.03 mg l-1 total dissolved phosphorus, 0.92 mg l-1 total nitrogen, 0.09 mg l-1 nitrogen as nitrate+nitrite, and 0.04 mg l-1 nitrogen as total ammonia.
The Great Lakes Basin Integrated Nutrient Dataset compiles and standardizes phosphorus, nitrogen, and suspended solids data collected between the 2000-2019 water years from multiple Canadian and American sources around the Great Lakes. Ultimately, the goal is to enable regional nutrient data analysis within the Great Lakes Basin. This data is not directly used in the Water Quality Monitoring and Surveillance Division tributary load calculations. Data processing steps include standardizing data column and nutrient names, date-time conversion to Universal Time Coordinates, normalizing concentration units to milligram per liter, and reporting all phosphorus and nitrogen compounds 'as phosphorus' or 'as nitrogen'.
The park monitors water quality on Clear Lake by sampling total phosphorus, Chlorophyll-a, oxygen consumption in the hypolimnion, and mean total phosphorus in the inflow streams. Nutrient and oxygen parameters will continue to change due to nutrient stress levels in the lake and thus, the targets and thresholds will change.
Thousand Islands NP monitors wetland water quality yearly in May/June. Samples are analyzed for multiple parameters including: total phosphorus, ammonium, nitrate, turbidity, and specific conductivity.
The Canadian Environmental Sustainability Indicators CESI program provides data and information to track Canada's performance on key environmental sustainability issues. The Phosphorus and Nitrogen Levels in the St. Lawrence River indicator reports on the status of total phosphorus and total nitrogen concentrations along the St. Lawrence River for the 2010 to 2012 period. The indicator rates nitrogen and phosphorus status based on whether total phosphorus and total nitrogen concentrations exceed Quebec's total phosphorus water quality guideline for the protection of aquatic life, and its total nitrogen water quality guideline for the protection of aquatic life. When phosphorus and nitrogen concentrations exceed their respective water quality guidelines, this exceedance indicates that phosphorus and nitrogen pose a greater risk to the health of the St. Lawrence River aquatic ecosystem.
