Surface-water and ground-water quality and aquatic life can be signiﬁcantly affected by the following principal issues identiﬁed in the Allegheny-Monongahela River Basin:
- Contaminants common to surface and under-ground coal mine discharge such as acidity, iron, aluminum, manganese, and sulfate.
- Volatile organic compounds (VOC’s), pesti-cides, and nutrients from increased urbanization.
- Runoff and loading of nutrients and pesticides to streams from nonpoint and point sources such as agricultural land uses.
- Radon in ground water.
