Route 146 Extension Lead impacted soils

Project Details

Technology: Ex-situ application of liquid reagents that react on contact to treat TCLP lead soils. Less than 1% increase in weight and 1,200 tons per day schedule easily achieved with minimal equipment and personnel. Standard hydraulic equipment used for stockpile mixing.
Regulatory: MA DEP Central Region
Type of material: Urban Fill & Slag
Contaminating metal: Lead (Pb)
Position: Remediation Contractor
Volume of media: 25,000 tons
TCLP baseline: 25 to 50 ppm range
TCLP treated: <0.1mg/l to ND

During the extension of Route 146 in Worcester, the Massachusetts Highway Department contracted Soil Solutions to perform patented ex-situ chemical fixation for lead impacted soils.

The soil was previously classified as hazardous waste and subject to expensive disposal fees and taxes.

The remediated soils were reclassified as non-hazardous and allowed for transport and disposal at a less expensive Subtitle D landfill.

Soil Solutions conducted treatability analysis to determine the proper chemical admixture and engineered the ex-situ remediation process to meet site conditions.

We then mobilized specialized process equipment and patented chemical stabilizers to perform the work, and managed all soil remediation, stockpile tracking, confirmation analysis, and transportation and disposal activities.
