Integrated Water Quality Monitoring and Assessment Report - Incl. Impaired Streams


The West Virginia Integrated Water Quality Monitoring and Assessment Report fulfills the reporting requirements under the federal Clean Water Act, Section 303(d) to provide a list of impaired waters and Section 305(b) to provide an overall assessment of West Virginia's waters to the U.S. Environmental Protection Agency. The term "waters" refers to lakes, wetlands, and streams.

During the development of the IR, the Section 303(d) list of impaired waters will be available for public review and comment. Ultimately, Total Maximum Daily Loads (TMDLs) will be developed for waters listed in the Section 303(d) list.

Public Comment Period for Draft Integrated Report

WVDEP has developed the Draft 2018/2020/2022 WV Integrated Report, including a draft 303(d) list of impaired stream and lake assessment units. An impaired water is a water body which fails to meet state water quality standards. By exceeding applicable water quality standards, impaired waters fail to support one or more of their designated uses, such as public drinking water supply, aquatic life propagation and maintenance, or contact recreation.

Public Participation

In order to allow public participation in the 303d listing process, public comments are being accepted through June 1, 2022.

Comments may be submitted by e-mail to or mailed to:

West Virginia Department of Environmental Protection
