Sources of Pollution

Historic manufacturing facilities caused contamination of an unnamed tributary of Brockport Creek. PCBs, cyanide, dioxins, furans and silver have been found at the AOC. 

AOC Boundaries

The Rochester Embayment is formed by the indentation of the Monroe County, NY, shoreline between Bogus Point in the town of Parma and Nine Mile Point in the town of Webster. The northern boundary of the embayment is delineated by the straight line between these two points. The southern boundary includes approximately 6 miles of the Genesee River that is influenced by lake levels, from the river's mouth to the Lower Falls. The drainage area of the embayment totals more than 3,000 square miles. This area consists of the entire Genesee River Basin and parts of two other drainage basins, the easternmost area of the Lake Ontario West Basin and the westernmost part of the Lake Ontario Central Basin.
