Scientists refined the existing national-scale "De facto Reuse Incidence in our Nation's Consumable Supply" (DRINCS) model for the Shenandoah River watershed.

Scientists deployed mobile fish exposure laboratories, such as these two, at sites in the Shenandoah River watershed, Virginia, to understand exposure and effects on fish.

One of the mobile fish exposure laboratories that were deployed at sites in the Shenandoah River watershed, Virginia. Fish were housed in the mobile laboratories and exposed to stream water or wastewater during the study to understand exposure and effects on fish.

Scientists deployed mobile fish exposure laboratories, such as these two, at sites in the Shenandoah River watershed, Virginia, to understand exposure and effects on fish. Inside the laboratories (see inset photo) fish were placed in aquariums, and exposed to stream water or wastewater during the study.

The USGS Mobile Atmospheric Mercury Laboratory has onboard instrumentation to measure aerosol concentrations and to continuously monitor mercury speciation and concentrations, air quality, automated wet deposition collection, and meteorological conditions.

Treated wastewater from Joint Base Cape Cod was discharged to rapid-infiltration disposal beds from 1936 to 1995. The disposal formed a groundwater contamination plume that extends more than 10 kilometers in the Cape Cod sand and gravel glacial outwash aquifer.
