Decreased acid deposition and the chemical recovery of Killarney, Ontario, lakes


Decreased acid deposition and the chemical recovery of Killarney, Ontario, lakes

Lakes in Killarney Park near Sudbury, Ontario, Canada, have shown dramatic water quality changes including general increases in pH and alkalinity, and decreases in SO42-, base cations and metals. While some lakes have recovered to pH >6.0, many are still highly acidic despite decades of improvement. Very high historical S deposition related to emissions from the Sudbury metal smelters dominated the acidification process in this region.
