Book ·
OSTI ID:5936444

This report was prepared to meet the requirements of Section 305(b) of the Clean Water Act (CWA). The Susquehanna River drains 27,580 sq mi in New York, Pennsylvania and Maryland, and contributes over half of the freshwater inflow to the Chesapeake Bay. The report covers 13,268 stream miles assessed out of 21,100 miles of named streams in the basin. The assessments over the Lower Susquehanna, Juniata and West Branch subbasins in greater detail than the Upper Susquehanna, Chemung and Eastern subbasins. Designated uses are attained in 11,812 stream miles (89% of the total). Ninety-four percent (12,520 stream miles) meet the CWA fishable water goal and 99% (13,223 stream miles) meet the CWA swimmable waters goal. Metals (mainly from mining activities) are the major cause of degradation, polluting 844 stream miles (58% of impaired stream miles). Nutrient enrichment and sediment from agricultural runoff and municipal wastewater discharges account for another 19% of degraded stream miles. At least 885 stream miles have elevated levels of toxic substances, mainly metals.
