Final 2016 305(b)/303(d) Water Quality Assessment Integrated Report

Key sections of the report

Approved by EPA on March 6, 2018

DEQ released the Final 2016 305(b)/303(d) Water Quality Assessment Integrated Report (Integrated Report) on April 2, 2018. The 2016 Integrated Report is a summary of the water quality conditions in Virginia from January 1, 2009, through December 31, 2014.

This biennial 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)
  • shellfishing
  • wildlife

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 7, 2017 and made available for public comment through September 6, 2017. 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 November 9, 2017 and February 22, 2018. EPA approved the revised report on March 6, 2018. The Public Comments and Response document contains comments received on the draft report and DEQ’s responses.

The Summary Presentation of the Draft 2016 Water Quality Assessment contains statistics presented at the public information webinar on August 24, 2017. A link to the recording of the presentation is available. Also, questions posed at the webinar were compiled and are addressed in the FAQ document.

Copies of the final report, summary presentation, public comments and responses, GIS data and associated maps can be ordered on CD at no charge by sending an email request. Please include your mailing address for prompt delivery.

The entire Final 2016 305(b)/303(d) Water Quality Assessment Integrated Report is a 79.6 MB bookmarked PDF available for download or scroll down to view and download the smaller individual components of the report.

All chapters of the report and the supplemental files are PDF documents. Please visit DEQ’s help page if you are unable to view these files.
