Investigation of Drivers of Harmful Algal Blooms on the Shenandoah River, Virginia

The U.S. Geological Survey (USGS), in cooperation with the Viriginia Department of Environmental Quality (DEQ) and collaboration with the Interstate Commission on the Potomac River Basin (ICPRB) is monitoring harmful algal blooms (HABs) on the two forks of the Shenandoah River in Virginia. Continuous and discrete water-quality and hydrology data is conducted to understand the drivers, persistence...

Harmful Algal Blooms Investigations at the Virginia and West Virginia Water Science Center

Excessive accumulations of algae that impair waterbodies, called harmful algal blooms (HABs), can have detrimental effects on aquatic ecosystems, reduce the quality of water resources, and can pose significant risks to human and animal health. The Virginia and West Virginia Water Science Center works with state, regional, and local partners to evaluate the drivers and distribution of harmful algal...
