Trace amounts of pesticides or volative organic compounds (VOCs) were detected in ground water sampled from public-supply wells in Salt Lake Valley if the age of the sampled water was less than about 50 years, according to a report recently released by the U.S. Geological Survey (USGS).

A 5-year study by the U.S. Geological Survey on the occurrence and distribution of trace elements and synthetic organic compounds in sediment and fish from the Great Salt Lake Basin area of Utah, Idaho, and Wyoming found that trace elements were elevated in areas affected by historic mining, and organic compounds were highest at sites with urban and agricultural land use.

Water samples collected by the U.S. Geological Survey (USGS) in areas surrounding the Great Salt Lake in parts of Utah, Idaho, and Wyoming generally meet existing guidelines for drinking water and the protection of aquatic life, although water quality in some specific areas have elevated concentrations of pesticides...
