Ground-Water Recharge Affects Fate of Petroleum Contaminant Plumes
U.S. Geological Survey (USGS) scientists have discovered that rainwater recharging the water table above petroleum contamination plumes affects how plumes grow and the rate that petroleum products (in this case crude oil) degrade and weather in ground water. The amount of recharge affects the migration of oil in the subsurface, how chemicals dissolve from the oil into ground water, and the...
Glyphosate Herbicide Found in Many Midwestern Streams, Antibiotics Not Common
Researchers with the U.S. Geological Survey (USGS) recently investigated 51 streams in nine Midwestern States to determine the presence of a wide range of herbicides, their degradation byproducts and antibiotics. Herbicides were detected in most water samples, which were collected to coincide with runoff events following herbicide application, but antibiotics were detected in only 1 percent of the...
