Geochemical and Microbiological Processes that Affect Migration and Natural Attenuation of Chlorinated Solvents in Fractured-Sedimentary Rock — Naval Air Warfare Center (NAWC) Research Site, West Trenton, NJ
USGS scientists will update research progress through several presentations at the National Groundwater Association (NGWA) Conference on Groundwater in Fractured Rock, September 28-29, 2015 in Burlington, Vermont. Project scientist Paul Hsieh will present the conference keynote address: "Flow and Transport in Fractured Rocks — Retrospective and Look Ahead."

In 1993, the U.S. Geological Survey
(USGS) began studies of contamination in fractured-sedimentary bedrock in
cooperation with the U.S. Navy at the former Naval Air Warfare Center (NAWC), West
In 2001, the USGS Toxic Substances Hydrology Program initiated research at
the NAWC to complement and expand the research being conducted on groundwater
flow and contaminant transport in fractured bedrock at its Mirror Lake, New
Hampshire Research Site. The
NAWC site was chosen because the general hydrogeologic framework was well
defined and the site contained extensive contamination over a range of
geochemical conditions. Site groundwater contains volatile organic compounds (VOC's) that include trichloroethene (TCE), cis-1,2-dichloroethene, and vinyl chloride.
The research will provide
understanding of the physical, chemical, and microbial processes that affect the
transport and fate of chlorinated solvents in fractured-sedimentary-rock
aquifers, including the role of dense non-aqueous phase liquids (DNAPL) as a
long-term source. The research also will develop methods for cost-effective
at the site is a multidisciplinary, collaborative effort that presently involves
scientists from the USGS, U.S. Navy, and several academic and private research institutions.
