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.

America’s rivers and streams are generally suitable for irrigation, supplying drinking water, and home and recreational uses. However, in areas with significant agricultural and urban development, the quality of our nation’s water resources has been degraded by contaminants such as pesticides, nutrients, and gasoline-related compounds.
