Contaminants in water can have acute and chronic impacts on aquatic organisms that depend on water for some part of their life cycle. The number of exceedances of contaminants with published Provincial Water Quality Objectives or Canadian Water Quality Guidelines for the Protection of Aquatic Life has been summarized for each station, using the most recent sampling years. In Lake Ontario, the most recent MECP sampling years are 2006, 2009, 2012; in Lake Erie,2007, 2010, 2014 and 2016; and in Lake Superior, these arefrom 2016 & 2019 (ECCC) and 2011 (MECP).Data is from the Ontario Ministry of Environment, Conservation and Parks Great Lakes Nearshore Index Station Networkand ECCC's Great Lakes Water Quality Monitoring and Surveillance Data.Low Stress: 0 exceedances;
