Project Details

  • Technology: Process to meet two goals: treatment of lead-impacted soil and solidification for strength. Specialized equipment including longreach excavators and dewatering systems used.
  • Regulatory: MA DEP Consent Order
  • Type of material: Lead-Impacted Settling Lagoon Waste
  • Position: Site Remediation Contractor
  • Contaminating metal: Lead
  • Volume of media: 8,000 processed tons
  • Type Ex-Situ Treatment, In-situ Solidification
  • Treatment goals: 0.75 mg/l TCLP Lead plus physical properties (strength, compaction, etc)
Soil Solutions HMR was contracted for the remediation of Lead impacted sediments in a settling lagoon at the American Optical facility in Southbridge, MA.

The remediation included treatment design and testing, the treatment of lead-impacted lagoon sediments, and the solidification of the treated material for use as a pavement base.

Soil Solutions and their subcontractors conducted both in-situ and ex-situ treatment for 8,000 tons of lead impacted sludge using proprietary liquid and dry treatment reagents.

The material was reused on-site and treatment standards for lead were set at 0.75 mg/l by TCLP analysis.

Soil Solutions also operated extensive dewatering systems during the project and completed site restoration activities.
