Total Maximum Daily Load (TMDL)
Our local watersheds are classified as impaired by the Commonwealth of Virginia. On a larger scale this includes the Potomac River and the Chesapeake Bay for bacteria and nutrients. As a result a TMDL, or "pollution diet," is required. It describes the maximum amount of a pollutant that a stream can receive and still meet water quality standards.

Best Management Practices (BMPs)
BMPs are a part of the solution because they treat stormwater runoff. By using these practices we can mitigate the amount of pollutants getting to our streams and eventually the Chesapeake Bay. Below you can find information on BMPs and organizations that are helping to ensure a healthy watershed.
