Abstract

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.

Introduction The Earth changes continuously in response to natural processes and human activity. The collection and interpretation of time-series imagery enhances our ability to observe and monitor Earth’s dynamic processes as well as study and understand the rapidly changing surface of our planet. The Global Fiducials Library (GFL) provides repeated satellite imagery of selected locations around the world to help scientists observe, document, and better understand those changes over time.
