  • Dry Cleaner Remediation

    Real Estate Developer; New Jersey

    Roux Associates designed and is currently implementing an innovative remedy using pneumatic fracturing and atomized injections of Zero Valent Iron and Emulsified Vegetable Oil to remediate a chlorinated solvent groundwater plume and Soil Vapor Extraction to remediate unsaturated soil. Work is being conducted within framework of the New Jersey Site Remediation Reform Act (SRRA).

  • Shopping Center

    Real Estate Developer; Indiana

    Subsurface chlorinated solvent contamination originating from a former dry cleaner operation at this 9-acre site was assessed by Roux Associates. Remedial activities have included focused soil excavation, in-situ enhanced reductive dechlorination, and the operation of a sub-slab depressurization system (SSDS). All work was completed while the site remained active and did not impede with daily operations.

  • In-situ Solvent Remediation

    Property Management Company; New York

    Roux Associates cleaned up this site which had been impacted by chlorinated solvents from a dry cleaner.

  • DNAPL & Groundwater

    Dry Cleaner; Massachusetts

    Roux Associates successfully remediated DNAPL and groundwater contamination at a former dry cleaner allowing continued use of all site buildings including an elementary school and apartments. Remediation included: air/liquid-oxidant injection; groundwater re-circulation; and soil vapor extraction. Roux efforts kept the site out of the Public Involvement Plan program, increasing speed and reducing costs.

  • Remediation of PCE

    Uniform Manufacturer/Insurance Carriers; New Jersey

    Roux Associates was retained as the consultant for the remediation of PCE from a dry cleaning operation at a uniform manufacturer. The former consultant’s remediation design called for several iterations of in situ treatment technologies and soil excavation for a cost of $6.7 Million dollars. Roux Associates reviewed the remedial approach and developed a more streamlined approach of soil vapor extraction/air sparging and monitored natural attenuation. The total estimated cost is $3 Million dollars. After two years of operation, the remediation has the soil and groundwater concentrations near cleanup standards – more than four years sooner than expected by the previous consultant.

  • Former Dry Cleaner Remediation

    Local Developer/Insurance Carriers; New Jersey

    Roux Associates designed a remediation approach addressing soil that was the source of groundwater contamination and indoor vapors. The approach entailed excavation of the clay-rich soil, periodic extraction from monitoring wells in the most contaminated groundwater area, and monitoring natural attenuation of the dissolved phase contamination. This work is complex with multiple food service tenants, a densely developed area and multiple other sources of PCE groundwater contamination. The previous consultant had under estimated the extent of the groundwater contamination at the site. Roux Associates identified this discrepancy and at the insistence of the insurance carriers assumed the role as lead consultant.
