Estrogen equivalents of surface water in Pennsylvania, 2012-2017

The data were gathered as part of a long-term, seasonal assessment of estrogenicity in selected locations within Pennsylvania from 2012-2017. Data were collected over this time frame to determine seasonal and annual changes in surface water estrogenicity.Estrogen is reported as estrogen equivalents (EEQ) as determined by a bioluminescent yeast estrogen screen. A total of 193 grab water samples wer

Soil Chemistry and Quality Control Data in support of Environmental Monitoring at the Open Burning/Open Detonation (OB/OD) areas in the Ammunition Area (AA) at Letterkenny Army Depot, Chambersburg, Pennsylvania, 2021

Soil sampling was needed to provide analytical soil data for areas near the Open Burning/Open Detonation (OB/OD) areas in the Ammunition Area (AA) of Letterkenny Army Depot. The U.S. Geological Survey sampled 10 locations and prepared the samples for chemical analyses. Samples were collected from depths of zero to six inches with a stainless-steel trowel. Multiple subsamples (10-20) were homogeniz

A finite-difference algorithm used to simulate radial diffusion, adsorption, and reactions of chlorinated ethenes in porous media

Simulations of radial diffusion, adsorption, and reactions of volatile organic compounds (VOCs) - trichloroethene (TCE), cis-1,2-dichloroethene (cDCE), vinyl chloride (VC), trichlorofluoroethene (TCFE) - and bromide (Br) in a porous media are conducted using rock properties identified from a mudstone aquifer in the Newark Basin, near West Trenton, New Jersey. The simulations are conducted using a

Surrogate regression models for computation of time series suspended-sediment concentrations, Chester County, Pennsylvania (2020)

The U.S. Geological Survey (USGS), in cooperation with the Chester County Water Resources Authority (CCWRA), has collected discrete stream samples for analysis of suspended-sediment concentrations at seven gaging stations where near real-time continuous data on stream discharge, and turbidity have been collected since 2005. Historical regression equations to estimate suspended-sediment concentrati

Data compilation for regional synthesis of chemical characteristics of groundwater used for domestic supply in north-east and north-central Pennsylvania

Groundwater quality data for 472 domestic well-water samples were retrieved from the USGS National Water Information System (NWIS) database and combined with descriptive information on the sampled well locations. The NWIS data for a sample, collected on the selected date, were averaged into a single record (one per well), and rounded according to USGS protocols. For evaluation and reporting, the w

Data in support of study evaluating effects of legacy-sediment removal on nutrients and sediment in Big Spring Run, Lancaster County, Pennsylvania, 2009-15

The stream corridor at the Big Spring Run restoration site has been identified as a substantial source of sediment and nutrients to streams due to streambank erosion and floodplain scour of legacy sediment. Three USGS streamgages were installed and water-quality monitoring began in water year 2009, prior to the legacy sediment removal from the restoration area. The legacy sediment was removed from
