This environmental restoration report for Sandia National Laboratories describes the implementation of Phase 1 of a phased treatability study/interim measure of in situ bioremediation (ISB) to evaluate the effectiveness of ISB as a potential technology to treat dissolved-phase TCE in the Technical Area-V groundwater area of concern. Phase I includes a pilot test followed by full-scale injection at the first injection well (TAV-INJ1); Phase II will include full-scale injections at two more injection wells if warranted by the findings of the Phase 1 full-scale operation. The pilot test began in November 2017 at injection well TAV-INJ1 and two nearby monitoring wells. Two gravity-fed injections of ~4,500 gal each to deliver substrate solution and biodegradation bacteria to the groundwater were completed on November 22 and 27, respectively. Section III of this report (PDF pages 58-64) provides a summary of the pilot test activities and associated results. https://hwbdocuments.env.nm.gov/Sandia%20National%20Labs/2018-10-19%20ER%20Operations%20Consolidated%20Quaterly%20Rpt%20Apr%202018%20-%20Jun%202018.pdf See the October-December 2018 quarterly report (PDF pages 50-57) for information on the Phase I full-scale injection activities: https://hwbdocuments.env.nm.gov/Sandia%20National%20Labs/2019-04-22%20ER%20Operations%20Consolidated%20Quarterly%20Rpt,%20Oct%20-%20Dec%202018.pdf
