Removal of Legacy Sediments Effects Nutrient Loads in Streamflow
Effects of Legacy Sediment Removal on Nutrients and Sediment in Big Spring Run, Lancaster County, Pennsylvania, 2009–15
USGS provides monitoring, analysis, modeling and research on streams and water quality to better understand the fate and transport of nutrients and sediment to the Susquehanna and other rivers, and their tributaries, and eventually to the Chesapeake Bay. Additional research focuses on emerging contaminants and other stressors that effect human and aquatic life in the watershed and estuary.

Water Quality to Inform Conservation Management
The occurrence and distribution of nutrients, and an understanding of biogeochemical processes aims to help aid conservation efforts.
The Susquehanna River drains the largest watershed (48 percent) and supplies 55 percent of the freshwater flowing into the Chesapeake Bay. In 2010, the largest and most complex total maximum daily load (TMDL) in the Nation was initiated in the Chesapeake Bay for nitrogen, phosphorus, and sediment. These pollution allocations were further divided by major river basins and states. Pennsylvania contributes approximately 44 percent of the nitrogen load and 24 percent of the phosphorus load to the Bay (Chesapeake Bay TMDL Document).
