Bioremediation of Explosives-Contaminated Soil, Hawthorne Army Depot, Nevada. The Company was awarded this competitively procured environmental remediation, multiple-award FFP, IDIQ contract for $5 million over 3 years.  The delivery order was competed among three contract awardees. The Company was selected on best value and best price. The Company provided remedial action services that included excavation and on-site bioremediation of explosives-contaminated soil from surface impoundments within the solid waste management unit B-29 area. This area was comprised of a series of unlined ponds used to receive wastewater for demilitarization activities.  Over the years, explosive-ladened washwater was discharged from the buildings to the ponds. The primary contaminant of concern consisted of ammonium picrate and lesser amounts of other explosive compounds. The performance goal was to remediate 2000 cy of soil per month. The Company exceeded this monthly remediation performance goal. We successfully remediated 12,000 cy of soil in 3.5 months achieving a production rate of 3400 cy/month (a 70% increase above the target goal).

Bldg 816, Navy Mole, Long Beach, California. The Company performed soil remediation during the BRAC and POLB redevelopment. Several innovative approaches were evaluated in selecting the best remedial action for this project (e.g., bioventing, insitu remediation, land tilling and phytoremediation). These alternatives, however, could not be implemented due to time constraints of demolition and redevelopment for future land use.  The best remedial alternative was to perform remediation consisting of soil excavation and off-site thermal desorption.  The Company participated in the BCT meetings for coordination and provided delivery order updates. Prior to excavation, the Company prepared, submitted and obtained the required SCAQMD Rule 1166 permit.  The primary objectives for this DO were to: (1) reduce the potential for adverse effects to human and ecological receptors from exposure to TPH contaminated soil, (2) reduce the potential threat to groundwater, and (3) achieve a recommendation of No Further Action (NFA). The TPH contaminated soil with concentrations above the RWQCB Maximum Soil Screening Level (SSL) of 10,000 mg/kg for TPH (diesel) above non-drinking aquifers (RWQCB, 1996) was removed and thermally desorbed off-site. During two excavation phases, over 12,000 tons of TPH contaminated soil were removed and thermally desorbed off-site. The SSLs were applied to sampling results to assess and confirm successful removal activities of diesel-impacted soil below 10,000 mg/kg SSL. After the second phase of excavation, analytical results showed diesel concentrations below the SSL. The Company completed the project four months ahead of schedule and obtained an NFA for the site from RWQCB-Los Angeles and US-EPA Region IX.

Innovative Remediation, NTC Fort Irwin, California.  The Company performed remediation of POL-contaminated soil by implementing an innovative re-utilization technique.  The Company successfully implemented the innovative cold mix technology (encapsulation) to obtain an asphalt product, which was used effectively as base material for parking lots and roadways.  The Company’s recommended approach to use stockpiled soil in this manner resulted in reducing the long-term liability and exceeded the federal recycling requirements.  The initial delivery order (DO) served as a pilot study in determining the effectiveness and durability of the remedial product. A total of 7400 tons of petroleum, oil, and lubricant (POL)-contaminated soil (DO01) and 8600 tons of soil (DO27) were processed at the NTC.  Previously stockpiled soils were recycled into concrete and asphalt materials using cold mix asphalt stabilization technology.  The recycled material was used in the repaving of three separate parking lots, the construction of a new lot at the salvage yard, and as base material for construction of a 2500–foot roadway.  The Company collected confirmatory samples of the material for TCLP analyses to determine the leachate potential of BTEX and TRPH components.  The material met all San Bernardino Fire Department-HazMat and DTSC requirements for reuse. The Company prepared and submitted comprehensive work plans, interim data updates, permits, and closure reports.
