【 摘 要 】

In 2010, a Total Maximum Daily Load (TMDL) was established for the Chesapeake Bay, setting limits on emissions of nitrogen, phosphorus, and sediment necessary to reverse declines in the Bay's quality. Agriculture is the largest source of nutrients and sediment in the watershed. The cost of achieving water quality goals depends heavily on which policies are selected and how they are implemented.
