Environmental monitoring of groundwater, surface water, and soil at the Ammonium Perchlorate Rocket Motor Destruction Facility at the Letterkenny Army Depot, Chambersburg, Pennsylvania, 2021
Letterkenny Army Depot in Chambersburg, Pennsylvania, built an Ammonium Perchlorate Rocket Motor Destruction (ARMD) Facility in 2016 to centralize rocket motor destruction and contain all waste during the destruction process. The U.S. Geological Survey has collected environmental samples from groundwater, surface water, and soils at ARMD since 2016.During 2021, samples were collected from four gro
Estimation and comparison of 1-percent annual exceedance probability flood flows at Federal Emergency Management Agency flood insurance study flow locations across Pennsylvania
Flood-flow estimates were computed at over 5,000 Federal Emergency Management Agency (FEMA) flood insurance study (FIS) flow locations across Pennsylvania for the 1-percent annual exceedance probability flood event (1-percent AEP). Depending on a point of interest’s proximity to a streamgage, weighting techniques may be applied to obtain flood-flow estimates for ungaged flow locations using observ
Results of 2018–19 water-quality and hydraulic characterization of aquifer intervals using packer tests and preliminary geophysical-log correlations for selected boreholes at and near the former Naval Air Warfare Center Warminster, Bucks County, Pennsylva
The U.S. Geological Survey (USGS) collected data on the vertical distribution of hydraulic head, specific capacity, and water quality using aquifer-interval-isolation tests and other vertical profiling methods in 15 boreholes completed in fractured sedimentary bedrock in Northampton, Warminster, and Warwick Townships, Bucks County, Pennsylvania during 2018–19. This work was done, in cooperation wi

Rapid Deployment Network for Flooding in Pennsylvania
USGS, in cooperation with the Federal Emergency Management Agency (FEMA) Region 3 and the Pennsylvania Department of Transportation (PennDOT), is developing a Rapid Deployment Network (RDN) for monitoring stream levels at currently unmonitored locations in Pennsylvania during flooding. RDN data helps emergency response agencies protect life and property during forecast floods and informs flood...

Contaminants in groundwater near former Navy bases in southeastern Pennsylvania
USGS has investigated groundwater flow and contaminant transport in the vicinity of former Navy bases in Bucks and Montgomery Counties, southeastern Pennsylvania, in cooperation with the U.S. Navy. Additional cooperative support for these investigations has been provided by the U.S. Environmental Protection Agency, Pennsylvania Department of Environmental Protection, Bucks and Montgomery counties...
