High concentrations of sediment-associated contaminants are typically associated with urban areas such as San Antonio, Texas, in Bexar County, the seventh most populous city in the United States. U.S.Geological Survey personnel periodically collected surficial streambed-sediment samples during 2007–09 and collected suspended-sediment samples from selected streams after storms during 2008 and 2009. All sediment samples were analyzed for major and trace elements, pesticides, polychlorinated biphenyls, and polycyclic aromatic hydrocarbons.
