Purgeable organic compounds in ground water at the Idaho National Engineering Laboratory, Idaho; 1990 and 1991

Abstract

Groundwater samples from 76 wells and 1 hot spring at or near the Idaho National Engineering Laboratory were analyzed for 36 purgeable organic compounds during 1990-91. The samples were collected and analyzed as a continuation of a water-quality program initiated in 1987, and as part of studies conducted by the U.S. Geological Survey. Most of the wells obtain water from the Snake River Plain aquifer. Samples were collected from these wells using dedicated or portable pumps. Water samples from 31 wells completed in the Snake River Plain aquifer contained detectable concentrations of at least 1 of 14 purgeable organic compounds. Most commonly detected were carbon tetrachloride, 1,1,1-trichloroethane, and trichloroethylene. The maximum concentrations of specific compounds in ground water were 5.0 micrograms per liter (ug/L) or less; the concentrations of most compounds were less than the reporting level of 0.2 ug/L. In addition, water from three wells contained detectable concentrations of one of two tentatively identified organic compounds, trimethylbenzene and isopropylbenzene.

“…From 1987 samples from many wells completed in the Snake River Plain aquifer at and near the INL were analyzed for VOCs for various water quality studies (Mann and Knobel, 1987;Liszewski and Mann, 1992;Bartholomay and others, 2000;Davis, 2006b. Analyses from these studies indicated that from 1 to 19 VOCs in water samples from several wells exceeded their reporting levels during these years.…”

“…Concentrations of from 1 to 19 VOCs, primarily carbon tetrachloride, 1,1,1-trichloroethane, and trichloroethylene, in water samples from 22 wells exceeded the MRLs. In 1990 and 1991, water samples were collected from 76 wells for various waterquality studies at or near the INL (Liszewski and Mann, 1992). Concentrations of from 1 to 14 VOCs, primarily carbon tetrachloride, 1,1,1-trichloroethane, and trichloroethylene, in water samples from 31 of these wells exceeded the MRLs.…”

“…From 1987 to 2008, water samples from many wells completed in the ESRP aquifer at and near the INL were analyzed for VOCs for various water quality studies (Mann and Knobel, 1987;Liszewski and Mann, 1992;Greene and Tucker, 1998;Bartholomay and others, 2000;Davis, 2006bDavis, , 2008Davis, , 2010.
