Sediment-quality and water-toxicity data from 10 sites on the Westside Creeks and San Antonio River, San Antonio, Texas, 2014

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).

Current-use pesticides and emerging amphibian pathogens in natural ponds, excavated ponds, and stormwater basins from 24 sites varying in land-use classifications throughout the New Jersey Pinelands, 2014-2016

Water, sediment, anuran food (leaf litter and detritus) and whole body larval amphibian composites were analyzed for over 100 current-use pesticides from 24 wetlands representing land-use gradients in the New Jersey Pinelands, USA during 2014-2016. Emerging amphibian pathogens, Ranavirus and Batrachochytrium dendrobatidis (Bd) were also assessed in individual larvae at the 24 wetlands. Tables in this data release contain the results from these analyses, with quality assurance summaries, along with site information, including land-use classifications.

PFAS, pesticide, and pharmaceutical concentrations in the Bronx River, New York, 2019 (ver. 1.1, January 2023)

This U.S. Geological Survey Data Release provides surface-water and bed sediment quality data at the Bronx River, New York, 2019. The data were collected with support from the Urban Waters Federal Partnership (UWFP) and others. Surface-water samples were collected at six locations along the Bronx River and analyzed for poly- and perfluoroalkyl substances (PFAS), pharmaceuticals, and pesticides. Water-quality field parameters such as pH, specific conductance dissolved oxygen, water temperature, and turbidity were measured during each site visit. Each surface-water site was sampled once under storm (wet) conditions and once under non-storm conditions (dry). 'Wet' samples indicate a precipitation event of 0.5 inch...

Land-Cover, Surface-Water, and Streambed-Sediment Data Collected Upstream From and Within an Area of Oil and Natural-Gas Production, South Texas, 2008-17

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...
