Concentrations of the compounds, however, were typically low. Moreover, VOCs in some domestic and public-supply wells were seldom at levels greater than Environmental Protection Agency guidelines. Nevertheless, the study said, “The widespread occurrence of VOCs indicates the ubiquitous nature of VOC sources and the vulnerability of many of the nation’s aquifers to low-level VOC contamination.”
U.S. Geological Survey report has found detectable levels of volatile organic compounds in groundwater and drinking water supply wells across the nation. The study, released April 28, found VOCs in 90 of 98 aquifers studied. Highest occurrences were in California, Nevada, Florida and New England and Mid-Atlantic states.
