About the Research


Eastern U.S. showing study location in northern Virginia and Clarksburg, Maryland.
Studies are focused in Montgomery County, Maryland including the Clarksburg Special Protection Area.

Using Best Management Practices (BMP) that effectively control urban stormwater runoff flow, affect groundwater levels, and reduce levels of nitrogen, phosphorus, and sediment in stormwater runoff is integral to meeting water quality goals in local streams and downstream in the Chesapeake Bay. U.S. Geological Survey (USGS) scientists are working in partnership with the Environmental Protection Agency (EPA), and local county partners to better understand how well BMP presence, type, and spatial pattern (in general, centralized or distributed use) moderate the amount of stormwater running off into streams and how well the BMP remove pollutants (including excess nitrogen, phosphorus, and sediment).
