Remediated over 5,000 tons of lead-impacted soil in situ at an operating manufacturing facility under the voluntary cleanup program (VCP) in Delaware. This required the preparation of a remedial action work plan and documentation report subject to public comment and review. Work was completed on a 0.5-acre site in a mixed residential and commercial area without affecting neighboring properties. The total project cost was more than 60 percent less than hazardous waste disposal.
