Key sections of the report
Approved by EPA on February 9, 2011
The Virginia Department of Environmental Quality (DEQ) released the Final 2010 305(b)/303(d) Water Quality Assessment Integrated Report (Integrated Report) on February 9, 2011. The 2010 Integrated Report is a summary of the water quality conditions in Virginia from January 1, 2003 through December 31, 2008. The Virginia Department of Environmental Quality develops and submits this report to the U.S. Environmental Protection Agency every even-numbered year.
The report satisfies the requirements of the U.S. Clean Water Act sections 305(b) and 303(d) and the Virginia Water Quality Monitoring, Information and Restoration Act. The goals of Virginia's water quality assessment program are to determine whether waters meet water quality standards, and to establish a schedule to restore waters with impaired water quality.
Water quality standards designate uses for waters. There are six designated uses for surface waters in Virginia:
- aquatic life
- fish consumption
- public water supplies (where applicable)
- recreation (swimming)
Additionally, several subcategories of aquatic life use have been adopted for the Chesapeake Bay and its tidal tributaries. The standards define the water quality needed to support each of these uses. If a water body contains more contamination than allowed by water quality standards, it will not support one or more of its designated uses. Such waters have "impaired" water quality. In most cases, a cleanup plan (called a "total maximum daily load") must be developed and implemented to restore impaired waters.
The draft Integrated Report was released on August 23 and made available for public comment through September 24, 2010. Comments were received from the public and the United States Environmental Protection Agency (EPA). In response to comments, the report was revised and resubmitted to EPA on December 10, 2010 and approved on February 9, 2011. The Public Comments and Response document contains comments received on the draft report and DEQ’s responses.
The Summary Presentation of the Final 2010 Water Quality Assessment contains statistics revised since it was given at the webinar in August. The answers to the questions posed at the webinar can be accessed in the FAQ document.
Copies of the final report, public comments and responses, revised summary presentation, GIS data and associated maps are all on a CD which can be ordered at no charge by sending an e-mail request.
