LEX ROCK REGIONAL WQCF - Lexington, Virginia Wastewater Treatment Plant

LEX ROCK REGIONAL WQCF is a wastewater treatment facility located in Lexington, Rockbridge County, Virginia. It serves a population of approximately 10,431 people, classifying it as a medium-sized municipal plant under U.S. EPA guidelines. As a U.S. facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Virginia Department of Environmental Quality. For a plant of this scale, secondary treatment is typically required, with possible nutrient removal standards to protect downstream waters. The treated effluent from the plant enters the local watershed, which flows into the James River and ultimately reaches the Chesapeake Bay. The Chesapeake Bay is a large estuary of ecological significance, supporting diverse aquatic life and commercial fisheries. The plant's nutrient management is critical to reducing pollution loads to this sensitive ecosystem.

The plant discharges into the James River basin, which drains into the Chesapeake Bay. The Chesapeake Bay is the largest estuary in the United States and supports a rich ecosystem including blue crabs, oysters, and migratory fish. Nutrient pollution from wastewater is a key concern, and the plant's performance affects downstream water quality and habitat health.
