The occurrence of volatile organic compounds in aquifers of the United States The occurrence of volatile organic compounds in aquifers of the United States

The U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program recently completed a national assessment of volatile organic compounds (VOCs) in ground water (Zogorski and others, 2006). As part of this assessment, samples of ambient ground water collected from 3,498 wells during 1985-2002 were selected for characterizing the occurrence of 55 VOCs in 98 aquifer studies...

Occurrence of volatile organic compounds in selected urban streams in the United States, 1995-2003 Occurrence of volatile organic compounds in selected urban streams in the United States, 1995-2003

The U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program sampled 37 urban streams throughout the United States for volatile organic compounds (VOCs) from 1995 to 2003. These urban streams were selected to (1) characterize stream water quality from areas draining predominantly residential and commercial land uses and (2) determine which natural and human factors...
