Former Scrap Metal Facility, Hagerstown, MD
Columbia was contracted to perform site remediation at a former scrap processing facility in Hagerstown , Maryland . The project was completed in three separate phases with the first being a response action to remove previously stockpiled hazardous and non-hazardous materials. The second phase was the demolition of the existing buildings and process equipment onsite.
The third phase of the project included the solidification/stabilization and excavation of 6,900 cubic yards of lead contaminated sediment from a storm water holding pond. Columbia solidified the sludge with Portland cement prior to the lead stabilization activity. Almost zero fugitive dust was emitted during the solidification portion of this project utilizing the company owned pneumatic dust filter.
Columbia utilized a stabilization agent to treat the lead impacted sediments from levels over 20 mg/L TCLP to less than 0.10 mg/L TCLP allowing the material to be disposed of as a non-hazardous waste. The stabilization of the waste saved our client over $700,000 in hazardous waste transportation and disposal cost. |
