Released on January 22, 2019

The Virginia Department of Environmental Quality (DEQ) released the Draft 2018 305(b)/303(d) Water Quality Assessment Integrated Report (Integrated Report) on January, 22, 2019. The 2018 Integrated Report is a summary of the water quality conditions in Virginia from January 1, 2011, through December 31, 2016.

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 Summary Presentation of the Draft 2018 Integrated Report was presented via webinar on February 13, 2019. The presentation recording is also available. After you register, the video will begin.

The report is available for public review and comment. Comments or questions about the report can be submitted via U.S. mail postmarked on or before February 21, 2019 to:

Sandra Mueller
Virginia Department of Environmental Quality
Office of Water Monitoring and Assessment
P.O. Box 1105
Richmond, VA 23218-1105
Or via email attachment to Sandra.Mueller@deq.virginia.gov (please include your name, mailing address, telephone number and email address)

A combined response to comments will be prepared after the public comment period expires and made available on this website with the final report.

Copies of the entire draft report including the summary presentation and associated maps are available on CD which can be ordered at no charge by sending an email request. Please include your mailing address for prompt delivery.

The entire Draft 2018 305(b)/303(d) Water Quality Assessment Integrated Report is a 40.3 MB ZIP file available for download or scroll down to view and download the smaller individual components of the report.

All chapters of the report are Microsoft Word files. The appendices and supplemental files are Word and PDF documents except for the Stations table which is an Excel worksheet. Visit DEQ’s help page if you are unable to view these files.

Attention GIS users:
The GIS data used in the production of the Integrated Report is under review for potential updates and corrections during the draft period but will be made available for download from this website as well as on CD along with the Final EPA approved Integrated Report. For more information or to obtain a copy of the CD, contact Cleo Baker.

Interactive Mapping:
Virginia Environmental Geographic Information Systems (VEGIS) - The impaired waters identified in this report can be viewed using DEQ's online GIS application which allows users to zoom to an area of interest and retrieve assessment information for specific waters. Appendix 5 can be used in conjunction with VEGIS to search for details on impaired waters.

Additional Information:
To obtain reports from previous assessment cycles, contact Cleo Baker or Amanda Shaver.

The Final 2018 305(b)/303(d) Water Quality Assessment Guidance Manual, released December 20, 2018, is also available.
