Spatial and temporal patterns in streamflow, water chemistry, and aquatic macroinvertebrates of selected streams in Fairfax County, Virginia, 2007–18

Urbanization substantially alters the landscape in ways that can impact stream hydrology, water chemistry, and the health of aquatic communities. Stormwater best management practices (BMPs) are the primary tools used to mitigate the effects of urban stressors such as increased runoff, decreased baseflow, and increased nutrient and sediment...

Science to support water-resource management in the upper Roanoke River watershed

Flooding, excessive sedimentation, and high bacteria counts are among the most challenging water resource issues affecting the Upper Roanoke River watershed. These issues threaten public safety, impair the watershed’s living resources, and threaten drinking water supplies, though mitigation is costly and difficult to manage.Urban development, land...

Chemical constituent concentrations in stream water, streambed sediment, and soils of Fort Belvoir, Virginia—A characterization of ambient conditions in 2019

IntroductionThe U.S. Army Fort Belvoir (FTBL) installation is on the banks of the Potomac River in Fairfax County, northeastern Virginia. The installation was founded by the U.S. Army during World War I. It has been home to a variety of military organizations over the course of its more than 100-year history and currently houses more than 145...
