King's Mill Park is located on the Humber River in Toronto. The park is built on an old landfill, which was officially closed in 1965. When a local fisher and LOK volunteer noticed what appeared to be leachate and a stron smell near the river, he brought the site to Lake Ontario Keeper's attention. LOK took samples in July, 2001. These results show that the leachate leaving the site and entering the Humber River exceeds Ontario's Water Quality Guidelines and violates Canada's Federal Fisheries Act. Lakekeeper Mark Mattson contacted the Ministry of Environment and visited the site with MOE officers. LOK presented them with its case file, and the government is now investigating.

"The city is serious about enforcing environmental laws," says Mattson. "Let's see them get serious about following them."

"It is my opinion that the City of Toronto must be prohibited from depositing this deleterious substance (i.e. leachate) into the Humber River and ultimately, Lake Ontario, which are waters frequented by fish," says Mr. Dillenbeck.
