Contaminants in Groundwater near Superfund sites in Pennsylvania

August 23, 2023
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 government agencies.
Highlights
- Many Superfund sites in southeastern Pennsylvania are underlain by Newark Basin fractured-sedimentary-rock aquifers, which historically have been used for industrial and drinking-water supply
- Field testing characterized the highly heterogeneous and anisotropic strata showing the predominant role of dipping bed-oriented fractures in contaminant migration
- Measured water levels in wells were used to construct water-level maps, and aquifer testing revealed high-permeability hydraulic connections between wells
- Groundwater-flow models were developed based on synthesis of monitoring data and field-test results for selected sites
- Simulations of transport paths were compared to observed contaminant distributions, and the simulated effect of changes in pumping on flow paths helped optimize pump and treat system operation
- Areas contributing recharge to streams and discharging wells were mapped using the groundwater-flow models; as groundwater withdrawals in the area have decreased, a higher proportion of local recharge ultimately discharges to streams
USGS has also investigated groundwater contamination in sedimentary and carbonate aquifers near Philadelphia and in fractured-rock aquifers near former Navy bases in southeastern Pennsylvania in cooperation with the U.S. Navy, EPA, Pennsylvania Department of Environmental Protection, and others.

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.

Contaminant Fate and Transport Studies in Fractured Sedimentary Rock Aquifers at the former Naval Air Warfare Center (NAWC), West Trenton, N.J.
Contaminants associated with industrial, airport, and other activities are present in groundwater in fractured-rock aquifers, posing long-term hazards to drinking-water supplies and ecosystems. The heterogeneous character of fractured rock challenges our understanding, monitoring, and remediation of such sites.
