Sediment samples and samples for water-toxicity testing were collected during 2014 from several streams in San Antonio, Texas known locally as the Westside creeks (Alazán, Apache, Martínez, and San Pedro Creeks) and from the San Antonio River. Samples were collected once during base-flow and again after periods of storm-water runoff (post-storm conditions) to determine baseline sediment- and water-quality conditions. Streambed-sediment samples were analyzed for selected constituents, including trace elements and organic contaminants such as pesticides, polychlorinated biphenyls (PCBs), brominated flame retardants, and polycyclic aromatic hydrocarbons (PAHs).

The diversion of freshwater from the Mississippi River is intended to mitigate saltwater intrusion from the Gulf of Mexico and to lessen the concomitant loss of wetland areas. Though effective, freshwater diversion can affect wildlife and habitat; therefore, prediversion and postdiversion data collections are necessary to identify effects. The Davis Pond freshwater diversion area is located between the Mississippi River and Bayou Lafourche and extends to Barataria Bay Basin, Louisiana. Results and interpretations from the prediversion biomonitoring done in 2001- which included data on fish, eagles, and bivalves - are presented in the U.S. Geological Survey (USGS) Scientific Investigations Report 2008-5067, "Davis...

Introduction As a result of storage and disposal practices at a former Manufactured Gas Plant, or MGP, in Bay Shore, NY, a variety of polycyclic aromatic hydrocarbons (PAHs) have been detected at high concentrations in the surficial, upper glacial aquifer of Long Island. Levels of PAHs initially detected over 10 years ago were in the parts-per-thousand range within a groundwater contaminant plume. The plume extended over a half-mile from MGP-related sources to discharge at a local estuarine tributary, Lawrence Creek, resulting, resulting in malodorous hydrocarbon sheens in this tributary and nearby storm drains. These signs of contamination revealed a larger underlying problem and prompted calls by state and local...

The dataset includes results from the analysis of sediments and solids collected from receptor sites receiving runoff from adjacent parking lots and other paved surfaces. Receptor sites include parking lot catch basins, retention ponds, drainage ditches, and storm-water discharge zones in streams and rivers. Samples were analyzed for percent moisture content and concentrations of 17 U.S. Environmental Protection Agency Priority Pollutant Polycyclic Aromatic Hydrocarbons (PAHs). Samples collected from parking lot sweepings (dust) also were analyzed for the same suite of 17 PAH compounds.

The extensive development of oil and natural-gas resources in south Texas during the past 10 years has led to questions regarding possible environmental effects of processes associated with oil and natural-gas production, in particular the process of hydraulic fracturing, on water and other natural resources. Part of the lower San Antonio River watershed intersects an area of oil and natural-gas production from the sedimentary rocks that compose the Eagle Ford Group. The rapid expansion of infrastructure associated with oil and natural-gas production increases potential pathways for inorganic and organic contaminants to enter surface-water systems. The U.S. Geological Survey, in cooperation with the San Antonio...
