Contaminant Fate and Transport Studies in Fractured Sedimentary Rock Aquifers at the former Naval Air Warfare Center (NAWC), West Trenton, N.J.
Field Method to Quantify Chlorinated Solvent Diffusion, Sorption, Abiotic and Biotic Degradation in Low-Permeability Zones
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.
Since 1993, USGS has been providing technical assistance to the U.S. Navy and conducting research at the former Naval Air Warfare Center (NAWC) in West Trenton, N.J., where trichloroethene (TCE) has migrated in fractures and diffused into, and adsorbed onto, low-permeability mudstone strata, acting as a long-term residual source of contaminants. These studies have helped the Navy efficiently monitor the ongoing natural attenuation of TCE and improve the pump and treat system to remove contaminants and contain impacted groundwater.
Current investigations are focused on understanding flow and transport processes affecting per- and polyfluoroalkyl substances (PFAS) in fractured-rock aquifers.
Research results include development of field methods to measure rates and coefficients associated with desorption, reaction, and diffusion of TCE and its degradation products in low-permeability strata (read more). In addition to research by USGS hydrologists, geochemists, and microbiologists, a broad range of studies on characterization, monitoring, and remediation of TCE in fractured rock have been conducted in collaboration with EPA, SERDP and ESTCP, academia, and private industry.
