USAFA completed a project review and graded MT2 with excellent marks.

Liability Mitigation

MT2 Services: The results of the site investigation found levels of lead above Indiana Department of Environmental management (IDEM) Risk Integrated System of Closure (RISC) for construction worker exposure and potential migration to groundwater and lead above hazardous levels as measured by TCLP. The project objective was to provide necessary and appropriate remediation and maintenance activities for the NAVSEA facilities following US EPA Best Management Practices for Firing Ranges, to minimize cleanup costs and address future potential liabilities that could negatively impact future use plans for NAVSEA. MT2 excavated, screened and treated lead-contaminated soils. Soils were treated with MT2’s proprietary stabilization reagent, ECOBOND® to meet the TCLP Pb requirements (concentrations below 5.0 mg/L). Treated soils were confirmed to meet action levels and TCLP requirements through sampling performed using laboratory analyses performed at an independent certified laboratory.

Outcome: MT2 excavated approximately 900 yards of lead-impacted soils from berms and pits associated with multiple rifle ranges. These soils were screened to separate bullets for offsite disposal and then tested for TCLP Pb. Soils were then treated with ECOBOND® to below the threshold of 5 mg/L for reuse on the site. Additionally, approximately 400 yards of soils were excavated from range soils that had the potential to impact groundwater. These soils were tested and soils above the TCLP lead threshold were treated with ECOBOND® for reuse onsite.
