Remedy Engineering was retained by a land developer to review historic data for an area that included 23 environmental sites, which had previously received closure for commercial/industrial use. The developer wants to build residential homes in the area. Following review and evaluation of the data, Remedy Engineering was able to demonstrate to the regulatory agencies that 16 of the environmental sites had been adequately characterized and remediated to meet the site-specific residential use standards. Remedy Engineering designed and implemented a plan to further investigate the remaining sites using direct-push technology. Results showed that only three of the remaining sites required further remediation in order to achieve closure from the regulatory agencies for unrestricted land use. Remedial actions, including excavation of contaminated soil and an in-situ chemical oxidation for petroleum contaminated groundwater have been implemented. Residential closure of the area is pending.
