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...
Stratigraphic framework and depositional sequences in the Lower Silurian regional oil and gas accumulation, Appalachian Basin: From Licking County, Ohio, to Fayette County, West Virginia Stratigraphic framework and depositional sequences in the Lower Silurian regional oil and gas accumulation, Appalachian Basin: From Licking County, Ohio, to Fayette County, West Virginia
The Lower Silurian regional oil and gas accumulation was named by Ryder and Zagorski (2003) for a 400-mile (mi)-long by 200-mi-wide hydrocarbon accumulation in the central Appalachian basin of the Eastern United States and Ontario, Canada. From the early 1880s to 2000, approximately 300 to 400 million barrels of oil and eight to nine trillion cubic feet of gas have been produced from the...
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...
Volatile organic compounds in samples from domestic and public wells, 1985-2002 Volatile organic compounds in samples from domestic and public wells, 1985-2002
The U.S. Geological Survey's (USGS) National Water-Quality Assessment (NAWQA) Program recently completed a national study of volatile organic compounds (VOCs) in the Nation's ground water (Zogorski and others, 2006). Part of this assessment emphasizes the occurrence of 55 VOCs in samples from 2,401 domestic wells and 1,096 public wells during 1985-2002. Samples were collected prior to...
