Groundwater, surface water, bed sediment, soil, benthic macroinvertebrate taxa and biological indices data collected near and at the Open Burning/Open Detonation (OB/OD) Areas at the Letterkenny Army Depot, Chambersburg, Pennsylvania, 2018-2021

Sampling is conducted by the U.S. Geological Survey (USGS) at nine wells, eight surface water sites, three bed sediment retention ponds, and two fields for soil samples at areas near and within the Open Burning/Open Detonation (OB/OD) areas in the Ammunition Area (AA) of Letterkenny Army Depot. Analytical results for groundwater samples collected from 2018-2021 are provided in “OBOD_wells_data_201

Altitude of selected beds and inferred faults in boreholes as identified from geophysical logs at Valmont TCE Site, Luzerne County, Pennsylvania

This dataset contains altitudes of selected beds and inferred faults in boreholes within an area of interest determined by the U.S. Environmental Protection Agency (EPA) at the Valmont TCE Superfund site in Luzerne County, Pennsylvania. The selected beds correspond to sections of borehole geophysical logs with elevated natural gamma activity as described in the U.S. Geological Survey (USGS) Open-F

Collection of Analytical Data for the Pennsylvania Groundwater Monitoring Network

This dataset contains all publicly-available analytical data collected by the U.S. Geological Survey (USGS) at each location within the Pennsylvania Groundwater Monitoring Network (GWMN) from 2015 to present. Additional analytical data will be appended following the conclusion of each sampling season, and all data is made publicly available in the online National Water Inventory System (NWIS). Thi

USGS-derived 1-percent Annual Exceedance Probability Flood-Flow Estimates at Flood Insurance Study Locations Across Pennsylvania

One-percent annual exceedance probability (AEP) flood-flow estimates were computed at flood insurance study (FIS) locations across Pennsylvania using methods identified in Scientific Investigation Report (SIR) 2019-5094. Following guidance outlined in SIR 2016-5149, valid statistical reaches (VSRs) were identified for streamgages, which were used to assist with the determination of the applicable

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

Waterborne Gradient Self-potential, Temperature, and Conductivity Logging of the Upper part of the Delaware River between Hancock and Port Jervis, New York, June-July 2021

This data release contains waterborne gradient self-potential (SP), surface-water temperature, surface-water conductivity and specific conductance, and surface-water nitrate concentration data measured continuously in the upper part of the Delaware River along approximately 123 kilometers (km) between Hancock and Port Jervis, New York. All of the data were measured from a kayak between June 27 and

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

Data for Characterization of Ambient Groundwater Quality within a State-wide, Fixed Station Monitoring Network in Pennsylvania, 2015-2019

This dataset contains quality-assurance and quality-control data (QA/QC) not publicly available in the online National Water Information System (NWIS) for the Pennsylvania Groundwater Monitoring Network collected by the U.S. Geological Survey (USGS) in Pennsylvania, 2015-2019. The quality-control data (such as blanks and replicates) were collected at a subset of sites to ensure that the data meets

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

Compilation of data not available in the National Water Information System for domestic wells sampled by the U.S. Geological Survey in Clinton County, Pennsylvania, May-September 2017

Clune, J.W., and Cravotta III, C.A., 2020, Compilation of data not available in the National Water Information System for domestic wells sampled by the U.S. Geological Survey in Clinton County, Pennsylvania, May-September 2017: U.S. Geological Survey data release, https://doi.org/10.5066/P9Q86Z7D.

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
