Treated Wastewater from Joint Base Cape Cod was Discharged
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.

The HBSL Database Contains 777 Contaminants
The HBSL database contains 777 contaminants currently or historically analyzed by the NAWQA Program. The database includes MCLs, HHBPs, or HBSLs for 351 contaminants. HBSLs are not available for the remaining 426 contaminants because of a lack of toxicity information.

Confluence of Cement Creek and the Animas River in Colorado
Although the visual picture of mixing zones at stream confluences appears straightforward, such as this one at the confluence of Cement Creek and the Animas River in Colorado, the chemical reactions that occur make them extremely complex from a water-quality perspective.

Cliffs near Sudley Springs along Bull Run, Manassas Battlefield, VA
Vegetation grows on an east-facing cliff along Bull Run near Sudley Springs in Manassas National Battlefield Park, Virginia. The cliffs are islands of specialized habitat; they support plant species found nowhere else in the park, including locally uncommon or rare species.

USGS Scientists Collecting a Water Sample from a Well at the USGS Bemidji Research Site
U.S. Geological Survey (USGS) scientists collecting a groundwater sample from a well at the USGS Bemidji Crude-Oil Spill Research Site, Minnesota. The scientists monitored in real time the dissolved oxygen, pH, specific conductance, and temperature of the water as the well is pumped so they can know when to collect representative sample.
