Median surface water hardnesses

This thematic layer represents the characterization of the hardness of surface waters in Quebec for the period 2005 to 2019. Hardness is presented according to medians calculated from calcium and magnesium ion concentrations in seven classes. Water hardness influences the toxicity of certain metals, including barium, beryllium, cadmium, chromium, copper, manganese, nickel, lead, and zinc. Surface water quality criteria are determined according to the hardness of the receiving watercourse. These criteria are used to judge the quality of surface water and are the basis for the groundwater criteria used to assess the quality of groundwater that is re-emerging into surface water. Finally, they are the key element in calculating environmental discharge objectives (OER) used to assess the quality of wastewater discharges into the aquatic environment. For a discharge that occurs on an annual basis, the median hardness of the receiving water body is generally used to calculate water quality criteria for aquatic life.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
