Volatile Organic Compound and Other Analyses Associated with Laboratory Microcosm Experiments to Determine Biodegradation Rates in Fractured Sedimentary Rock at the Former Naval Air Warfare Center in West Trenton, New Jersey, 2016–18 This metadata record presents analytical results for laboratory microcosms conducted during 2016–18 as part of a study to develop a field test and numerical interpretation method to determine the effective diffusion coefficients and sorption coefficients of trichloroethene (TCE) and daughter products in the rock matrix of sedimentary rock, as well as biodegradation rate coefficients in the borehole. The biodegradation rate coefficients in the borehole are an important component of defining the back-diffusion of TCE from the matrix of sedimentary rock. Microcosm experiments were conducted with microbial community samples and groundwater collected from boreholes in the field test area to define anaerobic biodegradation...

These experiments were conducted as part of a study to evaluate the feasibility of enhanced bioremediation for treatment of groundwater contaminants at White Sands Missile Range HTA site, New Mexico. Experiments included two anaerobic microcosm experiments, a culture enrichment test, and field injection test with the dechlorinating culture WBC-2. Data includes concentrations of nitrate, ammonium, perchlorate, RDX, and... Categories: Data; Tags: New Mexico, RDX, USGS Science Data Catalog (SDC), WBC-2 consortium, Water Resources, All tags...
