Microbial community analyses of groundwater collected during an enhanced bioremediation experiment of trichlorethylene in a fractured rock aquifer, West Trenton, NJ (2008-2015)

These datasets contain microbial community data from groundwater samples collected at an in situ bioremediation site located at the former Naval Air Warfare Center (NAWC), West Trenton, NJ. DNA was extracted from groundwater samples collected from monitoring wells at the NAWC study site from July 2008 through July 2015 and analyzed for microbial community structure. Sample collection coincided with a groundwater bioremediation experiment investigating the microbial degradation of the contaminant trichloroethylene (TCE) prevalent in the targeted region of the aquifer. Nutrient addition and a microbial consortium, commercially developed to stimulate the degradation of TCE and TCE byproducts, was introduced to the contaminated groundwater on October 15, 2008. This data release contains microbial community data including taxonomy, alpha, and beta diversity from next-generation sequencing of the V4 region of 16S rRNA from groundwater samples collected during the 7-year observation period. A further discussion and interpretation of the data is presented by Underwood et al. (Manuscript in progress).
