U.S. Geological Survey Report Released: Occurrence of Pesticides in Water and Sediment Collected from Amphibian Habitats Located Throughout the United States, 2009-10

Recently the U.S. Geological Survey (USGS) released a report, titled Occurrence of Pesticides in Water and Sediment Collected from Amphibian Habitats Located Throughout the United States, 2009-10, USGS Data Series: 707 (2012). In the 48 page report, here,
Water and bed-sediment samples were collected by the U.S. Geological Survey (USGS) in 2009 and 2010 from 11 sites within California and 18 sites total in Colorado, Georgia, Idaho, Louisiana, Maine, and Oregon, and were analyzed for a suite of pesticides by the USGS. Water samples and bed-sediment samples were collected from perennial or seasonal ponds located in amphibian habitats in conjunction with research conducted by the USGS Amphibian Research and Monitoring Initiative and the USGS Toxic Substances Hydrology Program.

Broken out into two geographic areas (national and for the State of California), scientists analyzed each water sample for 96 different pesitcides.  The report concluded that "[a] total of 24 pesticides were detected in one or more of the 54 water samples, including 7 fungicides, 10 herbicides, 4 insecticides, 1 synergist, and 2 pesticide degradates."
