TCE Treatability Study, Technical Area V



Since 2017, BGI has supported the environmental remediation project at Sandia National Laboratory (SNL) to conduct a phased treatability study of in-situ bioremediation (ISB) as a potential technology to treat groundwater contamination at Technical Area-V (TA-V) at Kirtland Air Force Base, Albuquerque, NM. Groundwater beneath TA-V is approximately 500 feet below ground surface and contaminated by trichloroethene (TCE) and nitrate. This project is being implemented in compliance with the April 2004, Compliance Order on Consent (the Consent Order) between New Mexico Environment Department (NMED), U.S. Department of Energy (DOE), and SNL which specified TA-V as an area of groundwater contamination and identified TCE and nitrate as constituents of concern (COCs) under the Resource Conservation and Recovery Act (RCRA).

BGI serves as the Prime Contractor that provides Program Management and ES&H support and oversees and certifies all work executed by lower tier contractors associated with the scope of work. The project scope includes construction, mobilization, and operation of an above ground injection system (AIS) and gravity-injected bioremediation solution in up to three injection wells. To date, construction of the AIS and the pilot test injection have been performed at the first injection well. Currently, operational testing of injection at the second injection well is underway.

BGI is documenting the bioremediation process/injections, groundwater sampling and analysis, and documenting groundwater plume TCE and nitrate concentrations to demonstrate the viability of bioremediation for degradation of COCs. We completed AIS Operation Reports at the end of the pilot-test and the full-scale injections for Phase I of the Treatability Study. Operation Reports included scope of activities, work performed, field conditions, observations, results, and recommendations for proceeding with Phase II along with proposed revisions to procedures. Following Phase II, we will complete Operational Reports documenting that phase. After Phase III, BGI will author a final report documenting activities and performance results from Phase I, II, and Phase III of the Treatability Study, synthesizing conclusions from all phases and making recommendations for completing remediation of the TA-V groundwater.

In support of this project, BGI translated work requirements and expectations, into a detailed Project Management Plan, a Contract Specific Safety Plan (CSSP), and an Activity Hazard Analysis (AHA). The CSSP incorporates DOE’s Integrated Safety Management System (ISMS) process and elements of Section 1065 Environment, Safety, and Health for Construction Contracts. The CSSP complies with DOE 10 CFR 851; OSHA General Industry (29 CFR 1910) and Construction Standards (29 CFR 1926); NIOSH Pocket Guide to Chemical Hazards; Occupational Safety and Health Guidance Manual for Hazardous Waste Activities (NIOSH/OSHA/U.S. Geological Survey/U.S. Environmental Protection Agency [EPA], 1985); and Threshold Limit Values and Biological Exposure Indexes, American Conference of Governmental Industrial Hygienists (ACGIH), 2016.
