Under the RCRA-based state cleanup, this risk-based closure involved planning, sampling, field analysis, soil and groundwater characterization, Geoprobe™, excavation, backfill, survey, landscaping, groundwater monitoring, and closure of this former seven-acre salvage yard with mixed hazardous lead and diesel range organic compound impacted soil. EMR investigated, designed, planned, and remediated the site that was near adjacent residential neighborhoods and alongside active railroad tracks, making lead remediation operations essential while requiring meticulous supervision to ensure human safety would not be threatened by site operations.
EMR determined that excavation would be the most cost-effective remediation option to meet project objectives, but disposal costs for the lead-contaminated hazardous waste soil were over twice that for non-hazardous soil. To minimize disposal costs, EMR implemented a bench scale test of lead-stabilizing compounds to evaluate whether soil could be efficiently converted to non-hazardous soil onsite. After achieving successful bench scale study results, EMR stabilized all lead-contaminated soils before hauling and disposal, thus cutting transportation and disposal costs in half. A total of 21,560 tons of soil was excavated and hauled as non-hazardous waste to disposal facilities
