About Presque Isle Bay AOC
The Presque Isle Bay AOC was located in the northwest corner of Pennsylvania, on the southern shore of Lake Erie. The bay is bounded by the mainland and City of Erie to the south and east, and Presque Isle to the north and west. The Presque Isle Bay watershed is about 25 square miles.
Waste disposal practices before state and federal regulatory programs were established had resulted in the discharge of industrial and domestic wastewater into the bay or to its streams and tributaries. This contaminated the bay with pollutants such as excessive nutrients, organic compounds and heavy metals. Point sources of pollution include steel mills, a foundry, water treatment plants and other industrial facilities. Combined sewer overflows and urban runoff contribute to nonpoint pollution.
