Data

The data include concentrations of current use pesticides in tissues of larval wood frog (Lithobates sylvaticus) and spotted salamander (Ambystoma maculatum) and the presence of ranavirus in wood frogs and spotted salamanders from three northeastern National Wildlife Refuges sampled in 2013 and 2014. The data also include estrogenicity, protein phosphatase 2A inhibition and a suite of 15 major and

This dataset contains a compilation of concentrations of chlorinated volatile organic compounds (VOCs) and per- and polyfluoroalkyl substances (PFAS) in groundwater and surface water sampled at the former Naval Air Warfare Center, West Trenton, New Jersey. Measured VOCs include trichloroethene (TCE), cis- 1,2-dichloroethene (cisDCE), and vinyl chloride (VC). Semi-volatile organic compound 1,4-diox

The data presented include concentrations of 10 metals in sediments and composite larval amphibian tissues from 20 wetlands across the United States. Sixteen of the wetlands were sampled in 2019 and four were sampled in 2015-2016. Where possible both larval anurans (frogs and toads) and salamanders were collected from each wetland. The data also include information on metal concentrations in amphi

A study conducted by USGS in cooperation with the New Jersey Department of Environmental Protection, measured and evaluated water levels in 10 confined aquifers of the New Jersey Coastal Plain to provide a regional overview of groundwater conditions during the fall of 2013. Water levels were measured in 987 wells in New Jersey, and parts of Pennsylvania and Delaware. Potentiometric-surface maps w

This USGS data release contains daily-timestep and monthly-timestep estimates of baseflow at 49 reference stream gages located within 25 miles of the Delaware River basin watershed boundary. Estimates are provided for the available period of record of streamflow data at each site between 1950 and 2015. A two-parameter recursive digital filter was used to estimate baseflow at the selected stream ga

Estimates of various low-flow statistics were computed at 53 ungaged stream locations throughout New Jersey during the 2019 water year using methods in the published reports, 1) Streamflow characteristics and trends in New Jersey, water years 1897-2003 (Watson and others, 2005) and 2) Implementation of MOVE.1, censored MOVE.1, and piecewise MOVE.1 low-flow regressions with applications at partial-

This data release provides state-level estimates of annual agricultural use of pesticide compounds by major crop or crop group for states in the conterminous United States, for the time period 1992-2017, compiled from data used to make county-level estimates by means of methods described in Thelin and Stone (2013) and Baker and Stone (2015). The source of these data is the same as the published co

This data release provides estimates of annual agricultural use of pesticide compounds in counties of the conterminous United States, for years 2013-17, compiled by means of methods described in Thelin and Stone (2013) and Baker and Stone (2015). For all States except California, U.S. Department of Agriculture county-level data for harvested-crop acreage were used in conjunction with proprietary C

The data were gathered as a preliminary assessment of estrogenicity under base-flow conditions at over 100 sites (lakes and streams) throughout New Jersey followed by more targeted sampling of smallmouth bass at nine sites with varying levels of estrogenicity. In 2016, 102 sites (lakes and streams) for the preliminary estrogenicity assessment were selected utilizing compiled results of previous mo

This dataset contains U.S. Navy contractor-reported groundwater level data measured on June 18, 2018 and reported daily total groundwater pump-and-treat withdrawal volumes for calendar year 2018 at the former Naval Air Warfare Center, West Trenton, New Jersey. This data release supports: Fiore, A.R., and Lacombe, P.J., 2020, Groundwater levels and generalized potentiometric surfaces, former Naval

This data release includes all pesticide results from selected batches of water samples analyzed by the U.S Geological Survey National Water Quality Laboratory (NWQL). Samples were analyzed using gas chromatography/mass spectrometry (GCMS) or liquid chromatography/mass spectrometry (LCMS) methods. Eight datasets are included in this data release; 1) all environmental and field quality control (QC)
