New Mexico Environment Department, 115 pp, 2018

Results of the in situ bioremediation treatability study pilot test in Technical Area (TA)-V are summarized in Section 3 of this report. TCE and nitrate were identified as COCs in groundwater at TA-V. The EPA MCLs and the State of New Mexico drinking water standards for TCE and nitrate are 5 µg/L and 10 mg/L (as nitrogen), respectively. A substrate solution containing ethyl lactate and nutrients for biostimulation was prepared in aboveground tanks. The substrate solution and augmenting bacteria (KB-1) were gravity-fed to groundwater via injection wells between November 21 and November 27, 2017.
