Contaminants in Groundwater near Superfund sites in Pennsylvania

USGS has investigated groundwater flow and contaminant transport in the vicinity of Superfund and other hazardous-waste sites in Pennsylvania, in cooperation with EPA. Additional cooperative support has been provided by the U.S. Department of Defense, National Park Service, Pennsylvania Department of Environmental Protection, Philadelphia, Bucks, Chester, and Montgomery Counties, and local...

Groundwater, surface water, and soil data collected near and at the Ammonium Perchlorate Rocket Motor Destruction (ARMD) facility at the Letterkenny Army Depot, Chambersburg, Pennsylvania

Sampling was conducted by the U.S. Geological Survey (USGS) at four wells, one surface water site, and five soil sampling locations near and at the Ammonium Perchlorate Rocket Motor Destruction (ARMD) facility at the Letterkenny Army Depot. Analytical results for groundwater samples collected in 2021 are provided in “ARMD_wells_data_2021.xlsx”. Analytical results for surface-water samples collecte

Water-quality data for six Resource Conservation and Recovery Act (RCRA) wells at Letterkenny Army Depot, Chambersburg, Pennsylvania

The U.S. Geological Survey (USGS) has collected water-quality data at six Resource Conservation and Recovery Act (RCRA) wells at the Letterkenny Army Depot since the 1990s. Electronic data (field and analytical) for this project were put into the USGS National Water Information System (NWIS) database beginning in 2017. Analytical data include total forms of selected metals and volatile organic com

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

Baseline environmental monitoring of groundwater, surface water, and soil at the Ammonium Perchlorate Rocket Motor Destruction Facility at the Letterkenny Army Depot, Chambersburg, Pennsylvania, 2016

Letterkenny Army Depot in Chambersburg, Pennsylvania, built an Ammonium Perchlorate Rocket Motor Destruction (ARMD) facility in 2016. The ARMD Facility was designed to centralize rocket motor destruction and contain or capture all waste during the destruction process. Ideally, there would be no contaminant transport to air, soil, or water from the facility, but the Code of Federal Regulations requ
