This USGS data release contains station and laboratory method information and geospatial information, as well as concentration results for inorganic and organic compounds and bioluminescent yeast estrogen screen and transgenic zebrafish embryo estrogren bioassay, analyzed at 38 sites in 25 states as part of the Chemical Mixtures and Environmental Effects Pilot Study, 2012-2014.

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.

Surface-water organic contaminant concentration data for targeted chemical analysis of over 800 organic analytes in surface water from 38 stream site representing national gradients in urban and agricultural land use in the USA during 2012-14. ScienceBase Data Release for journal article entitled, "Expanded Target-Chemical Analysis Reveals Extensive Mixed-Organic-Contaminant Exposure in USA Streams"

These data represent surface water and bed sediment samples analyzed for a variety of organic compounds. The samples were collected in streams and rivers in the Chesapeake Bay watershed from 2012-2018. Sites were located in Maryland, Pennsylvania, and West Virginia. Surface water samples were collected from 25 sites and analyzed for estrogenicity and an extensive suite of organic contaminants including hormones, pharmaceuticals, wastewater indicators, pesticides, phytoestrogens, and mycotoxins. Bed sediment samples were collected from 20 sites and analyzed for a suite of organic contaminants including hormones, wastewater indicators, pesticides, and organohalogens. Bed sediment was also analyzed for total organic carbon. Data also include replicate and blank quality assurance samples. This U.S. Geological Survey (USGS) data release contains daily-mean streamflow and water-quality data in the Chesapeake Bay watershed ranging from 2012 to 2018 (beginning and end dates may vary).

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.

Human-use pharmaceutical, pesticide, and wastewater indicator compounds were analyzed at the U.S. Geological Survey, National Water Quality Laboratory, Denver, Colorado, in wadeable streams in 4 Regional Stream Quality Assessments: Northeast (NESQA), Southeast (SESQA), Pacific Northwest (PNSQA) and California (CSQA). Multiple (with few exceptions) samplings occurred at each site, during base flow, between 2014 and 2017. Sites were located in the headwaters of perennial, wadeable streams in urban and agricultural watersheds. Site selection and methodology for each assessment can be found in Van Meter and others (2015), Sheibley and others (2015), Van Meter and others (2017), Coles and others (2016), Van Meter and others (2016), Journey and others (2015), and Van Meter and others (2014). Additional results for this study can be found in Bradley and others, 2020 and Mahler and others, 2020. See cross-reference section for full citation information.
