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...
Hydrologic, Water-Quality, and Ecological Monitoring and Analysis to Support Stream Restoration Research in Reston, Virginia
The U.S. Geological Survey, in cooperation with Resource Protection Group, Inc. is partnering with Reston Association to monitor the hydrology, water-quality, and ecology of two restored urban streams in Reston, Virginia – Snakeden Branch and The Glade. A combination of continuous and discrete hydrologic and water-quality data are collected to evaluate stream conditions and estimate sediment and...
Monitoring High-Priority Stream Crossings Along Proposed Natural Gas Pipeline Routes
The U.S. Geological Survey (USGS), in cooperation with the Virginia Department of Environmental Quality (DEQ), is monitoring the water quality of multiple high-priority streams where natural gas pipeline crossings have been proposed. The purpose of the monitoring effort is to collect baseline water-quality data and, if the pipeline construction is approved, to monitor water quality in these...
