Data from study assessing the utility of knowledgebase-leveraging of comprehensive environmental-contaminant-exposure datasets by comparing biological effects predicted on the basis of target chemical analyses with measured biological effects in corresponding split water samples.
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...

Water-quality samples were analyzed at two U.S. Geological Survey laboratories: National Water Quality Laboratory, Denver, Colorado and at the Redox Chemistry Laboratory, Boulder, Colorado.
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...

This dataset consists of summary data for potential landscape sources of per- and poly-fluoroalkyl substances (PFAS). These summary items include facilities from the Environmental Protection Agency (EPA) PFAS Analytics Tools, which were pulled from its Enforcement and Compliance History Online (ECHO), areas affected by fires (burned and urban burned areas) from Monitoring Trends in Burn Severity (MTBS), and landcover data from National Land Cover Dataset (NLCD) and Coastal Change Analysis Portal (C-CAP) around sites sampled as part of a National PFAS Tapwater Reconnaissance. These data are presented as a comma separated file, which includes summaries for all variables listed within a 5-kilometer buffer around each...

In the United States and globally, the lack of data on contaminant exposure from unregulated private-well point-of-use (POU) tapwater (TW) is a recognized public health data gap and an obstacle to risk management and homeowner decision making. Mead, Nebraska, is an agricultural community about 30 miles west of Omaha. To help address the lack of data on broad contaminant exposures in TW sourced from private water wells, a total of 22 samples were collected from 18 private wells during June 2022 and January 2023 and analyzed for 495 organic compounds, 34 inorganic constituents, and 11 microbial groups. The organic compounds included pesticides, pharmaceuticals, volatile organic compounds (VOCs), disinfection byproducts...

The dataset contains quantitative polymerase chain reaction data for microbial source tracking markers screened on water samples collected from streams and rivers within and bounding Congaree National Park from samples collected throughout the year from December 2017 through June 2019. The number of samples collected per event ranged from 4-16 over the span of 11 sample events.
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.1c06821. 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. The sampling site descriptions, analytical method descriptions, sample detection result determinations, and quality control data are provided within the tables and metadata of this data release.

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.
