MIT Lansdowne New Housing chemical fixation

Project Details

Technology: Liquid reagents and specialized storage and application equipment used during the new construction project. Portability of the system key to treatment of distinct areas identified by site engineers.
Regulatory: Massachusetts Contingency Plan (MCP)
Type: In-Situ Chemical Fixation Project
Position: Remediation Contractor
Contaminating metal: Lead (Pb)
Volume of media: 7,300 Tons
Type of material: Urban Fill
TCLP baseline: 5.2-390 ppm
TCLP treated: <0.75mg/l to ND

Soil Solutions was contracted to provide a cost-effective in-situ chemical fixation for MIT's new Lansdowne Street Housing project impacted with TCLP Lead-impacted soils.

The scope of the project included: bench-scale testing to determine the appropriate reagent and dose, mobilization of specialized chemical process equipment, application of the chemicals, confirmation analyses, and off-site transportation and disposal to an out-of-state lined Subtitle D landfill.

Soil Solutions successfully treated 7,300 tons of RCRA Hazardous waste to RCRA Non-Hazardous waste.

Treatment was performed in-situ using one (1) foot lift with surface tilling to achieve proper reagent contact and distribution.
