This metadata record contains 15 tables with results from field and laboratory tests used to assess bioremediation in wetland areas at the Standard Chlorine of Delaware, Inc. Superfund site, New Castle County, Delaware, during 2019-2021. Included in the dataset are (1) polychlorinated biphenyl (PCB) concentrations in wetland sediment from sediment microcosm laboratory experiments, (2) chlorobenzene concentrations in wetland sediment from sediment microcosm laboratory experiments, (3) polychlorinated biphenyl concentrations from PCB microcosm laboratory experiments using polyethylene strips, (4) chlorobenzene concentrations from PCB microcosm laboratory experiments using polyethylene strips, (5) total iron and ferrous...

The U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board collected produced water samples for analysis of volatile organic compounds (VOCs) in the eight California oil fields of Fruitvale, Lost Hills, North Belridge, Orcutt, Placerita, South Belridge, Midway-Sunset, and Buena Vista from 2016 to 2020. Sampled sites included oil wells; injectate from tanks, pipelines, and injection wells where produced water from many wells, after removal of oil, is stored or transported prior to underground injection; integrated produced water from many oil wells collected from pipelines before oil removal; and surface disposal ponds where produced water, after removal of oil, is disposed...

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...

This metadata record presents geochemical analytical data determined during laboratory experiments and a field pilot test collected during 2008-2010 to evaluate degradation of the cyclic nitramine explosive, hexahydro-1,3,4-trinitro-1,3,5-triazine (RDX), and perchlorate in a fractured rock aquifer. 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...

Anaerobic microcosm experiments were conducted in April-May 2018 with PFAS-contaminated soil from a U.S. Army installation (Fort Drum, New York) and simulated groundwater. All microcosms, except for a live sediment control, were amended with perfluorooctanesulfonate (PFOS), perfluorooctanoate (PFOA), and 6:2 fluorotelomer sulfonate (6:2 FtS). Replicate treatments were prepared with and without bioaugmentation with the WBC-2 dehalogenating culture and with and without addition of chlorinated volatile organic compounds (1,1,2,2-tetrachloroethane and trichloroethylene). Two additional treatments were prepared containing granular activated carbon. All microcosms were prepared in duplicate and sacrificed for sampling....
