This dataset contains results for samples collected at stormwater basins across the United States to assess the potential contaminant pathways of these basins to surface water and groundwater. Sample sites were in stormwater conveyance infrastructure that discharged mixed stormwater runoff from buildings, parking lots, roads, and other infrastructure in residential, commercial, and industrial landscapes prior to surface-water discharge or groundwater infiltration. Stormwater basins draining various types of urban environments, and of various drainage areas, were selected and sampled during storm events. The associated report (Masoner and others, 2019) can be found at https://doi.org/10.1021/acs.est.9b02867. A total of 438 organic compounds were analyzed including biogenic hormones, halogenated chemicals, household/industrial chemicals, methylmercury, pesticides, pharmaceuticals, and semi-volatiles. Additionally, 62 inorganic constituents were collected including cations and anions, rare-earth elements, trace elements and mercury. Rare-earth element and inorganic constituent data can be found in Jaeschke and others, 2018 and Keefe and others, 2018 (citations included in Cross Reference section of this metadata record). Concentration results and land-use descriptions are presented within.

This dataset presents the results of 475 unique organic compounds collected from 54 wadeable streams within the Southeastern, USA, collected within 10 weeks during 2014. Maximum and median exposure conditions were evaluated in relation to watershed characteristics and for potential biological effects. This dataset contains the summary statistics (maximum and median concentrations)of detected compounds, as well as a summary of quality-assurance (blanks and replicates) samples. Also included are the statistical summaries as related to analyte specific contaminant detection/concentration data and site-specific land-use matrices, spearman-rank correlations, and ToxCast evaluations.

These analyses provide the basic geochemical composition of urban stormwater runoff from rainwater/stormwater that does or has the potential to infiltrate groundwater from Green Infrastructure control measures. These measures are able to mimic the natural landscape with engineered designed systems to enhance stormwater infiltration to groundwater.

This dataset contains results for treated wastewater samples collected at food processing facilities across the United States to characterize the potential contaminant profile of this type of wastewater. The associated report (Hubbard and others, 2021) can be found at https://doi.org/10.1021/acs.est.XXXXXXX. Samples were analyzed by USGS laboratories using 10 target organic (576 unique analytes), 13 inorganic (32 unique analytes), and 18 microbial (15 bacterial groups) methods. Concentration results and site descriptions are presented within.

This data release contains the concentration and quality-assurance results for inorganic constituents, organic compounds (volatile organic compounds [VOC], per- and polyfluoroalkyl substances [PFAS], pesticides, and disinfection byproducts [DBP]) collected in tapwater from locations in Alabama and Mississippi. Tapwater samples (11 public supply and 1 private well) were collected on December 13-14, 2022, in Dallas and Wilcox Counties, Alabama. Fifteen tapwater samples (14 public supply and 1 private well) were collected in Panola and Oktibbeha Counties in Mississippi on February 6-7, 2024. Pharmaceuticals (for Alabama samples only), VOC, and PFAS were analyzed at the U.S. Geological Survey (USGS) National Water Quality Laboratory (NWQL) in Denver, Colorado. Pharmaceutical samples for the 15 samples collected in Mississippi, were analyzed at the USGS Organic Geochemistry Research Laboratory (OGRL) in Lawrence, Kansas. Pesticides and DBP were analyzed at the USGS Organic Chemistry Research Laboratory (OCRL) in Sacramento, California. Inorganic contaminants were analyzed at the USGS Redox Chemistry Laboratory (RCL), Boulder, Colorado, and the Analytical Trace Element Chemistry Laboratory (ATECL), Boulder, Colorado. Microbiological indicators were analyzed for samples collected in Mississippi at the Michigan Bacteriological Research Laboratory in Lansing, Michigan.
