Mine Drainage and Water Quality Research
The USGS Pennsylvania Water Science Center conducts research on geochemical and hydrological processes that control water quality, including the sources, transport, and attenuation of metals and nutrients in undisturbed and mining-impacted watersheds and aquifers.
Results apply to scientific and regulatory programs for the prevention and remediation of aquatic contamination.
