1,1,2,2-Tetrachloroethane (TeCA) contaminated groundwater at the Aberdeen Proving Ground discharges through an anaerobic wetland in West Branch Canal Creek (MD), where dechlorination occurs. Two microbially mediated pathways, dichloroelimination and hydrogenolysis, account for most of the TeCA degradation at this site. The dichloroelimination pathways lead to the formation of vinyl chloride (VC), a recalcitrant carcinogen of great concern. The goal of this investigation was to determine whether microbially-available Fe(III) in the wetland surface sediment influenced the fate of TeCA and its daughter products. Differences were identified in the TeCA degradation pathway between microcosms treated with amorphous ferric...

This metadata record contains a shapefile of site locations and 3 tables used to assess wetland elevation change over time and the long-term effects of sea-level rise to vulnerable tidal wetlands along the Edgewood peninsula of Aberdeen Proving Ground, Maryland. Included in the dataset are raw pin measurements of wetland sediment elevation and water levels measured for selected sites along Monks Creek and Swaderick Creek, in addition to water levels at the Marina along Bush River collected in 2018-2019. Contents of this data release have been approved for public release and unlimited distribution by the U.S. Army, clearance number 20021-4-33.
