Water Quality

In addition to the Overview information provided for Water Quality, the Agriculture and Wastewater Workgroups have described their priorities and progress in the tabs below. Other important work is being conducted by the Chesapeake Bay Program partnership to restore water quality by implementing pollution reduction practices on urban and suburban lands and reducing pollution deposited in the watershed from the air. Additional information on these efforts will be included over time. Progress in implementing the Bay Total Maximum Daily Load (TMDL) and in achieving milestones set at the 2009 Executive Council Meeting is also described below.

Best Management Practice Review

The Chesapeake Bay jurisdictions implement Best Management Practices (BMPs) to achieve the goals set forth in the 2010 TMDL. Through the Protocol for Development, Review and Approval of Loading and Effectiveness Estimates for Nutrient and Sediment Controls, newer practices and technologies are considered and evaluated for inclusion in the Chesapeake Bay Program partnership modeling tools. Existing practices are re-evaluated to ensure they reflect the best available scientific data and information. Below is a table depicting the BMPs identified for review and the status of those reviews.

Additionally, information is now available on receiving nutrient reduction credit for verifiable homeowner BMPs in Chesapeake Bay Program partnership modeling tools.
