Harmful algal blooms, fed by excess nutrients in the water, are a pressing environmental, economic and public health concern in water bodies across Canada. Government organizations on both sides of the Canada-US border are responsible for setting goals, overseeing implementation and monitoring, and evaluating outcomes of nutrient management. Decisions need to be made, and a [...]
Estimates of nutrient loadings to water bodies from municipal sources are typically calculated using point measurements of nutrient concentrations and known discharge rates. However, some uncertainty in load estimates is inevitable, and it is unclear how well nutrient monitoring methods typically used in Canada support decision making by watershed managers. With financial support from Environment [...]
Effectively managing nutrient losses from agricultural lands is critical for protecting water quality, and is a core focus in regions like the western basin of Lake Erie (Canada-Ontario Lake Erie Action Plan, 2018). With financial support from Ontario’s Ministry of Agriculture, Food and Rural Affairs, CWN led a project to provide an updated synthesis of [...]
Steadily increasing regulations and changing practices are gradually improving the quality of urban wastewater. By contrast, fewer controls or regulations deal with non-point-source discharges or effluent exceedances such as those that occur during extreme weather. With financial support from Environment and Climate Change Canada, Canadian Water Network led a project to examine the state-of-the-knowledge on [...]
