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).

Mountain Creek Lake is a reservoir in north Texas 8 miles southwest of Dallas, Texas where historical contamination by polychlorinated biphenyl compounds (PCBs) and other organic contaminants has been reported. There was a need to reassess concentrations of contaminates of organic and inorganic compounds in the reservoir. In cooperation with the City of Dallas, the U.S. Geological Survey (USGS) sampled Mountain Creek Lake and two downstream stream sites over two sampling events. The study area consisted of seven sites on Mountain Creek Lake, one site on the Trinity River, and one site on Mountain Creek. Water-column and bed-sediment samples were collected at each site in June and August of 2019. Water-quality field...
