On September 3rd, 2008, the U.S. Environmental Protection Agency (EPA) proposed the addition of the BoRit Asbestos Site, located by the Wissahickon Creek at the intersection of Whitpain Township, Upper Dublin Township and Ambler Borough, to the Superfund National Priorities List (NPL).

Coal-burning power plants are the largest industrial source of mercury emissions in the United States, and ten percent of these emissions come from plants in Texas - more than any other state. Five of the nation's top ten emitters of mercury are in the Lone Star State.

When mercury is released into the air, it settles in rivers, lakes, and streams. Bacteria in the water convert it to methyl mercury, a very toxic form of mercury. The toxic mercury bioaccumulates in the bodies of animals. Eating contaminated fish is the main way people are exposed to unsafe levels of mercury. Unlike with some other toxins, there is no way to clean or cook mercury out of fish.
