TMDL Development

Virginia's goal is that all streams attain the appropriate beneficial uses. These beneficial uses are described by the following use goals:

  • drinking water use
  • primary contact/swimming use
  • fishing use
  • shellfishing use
  • aquatic life use
These uses are protected by application of the state's numeric and narrative water quality criteria. When the beneficial uses are not being met, the state must take steps to ensure that water quality is restored. One very important step in restoring water quality in the impaired streams is the development of TMDLs. A TMDL Study identifies sources of pollution and reductions needed from the identified pollutants to attain water quality standards. Pollution from point sources such as residential, municipal, or industrial discharges and non-point sources such as residential, urban, or agricultural runoff are included in the TMDL study. The links below will allow you to access information regarding ongoing and upcoming TMDL projects in the development phase.
