Residential Heating Oil – Old Bridge, NJ
Light Non-Aqueous Phase Liquid (LNAPL) and Petroleum Hydrocarbon Soil Treatment
Traditional excavation could not be completed safely at the site. Under a Pay-for-Performance contract, ERFS completed remedial activities for this approximately 420 square foot area entirely beneath a concrete slab on grade structure. The treatment depth interval was from 6 to 16 feet below ground surface (bgs). Groundwater was encountered at the site at approximately 8 - 10 ft bgs. Subsurface soils were silty fine to medium sand from grade to 6 feet below ground surface (bgs), and tight clayey silt from 6 feet bgs to 20 feet bgs. The project was completed through funding by the homeowner’s insurance. ERFS installed Propagations, infiltration laterals and vertical injection wells followed by successive treatments using chemical oxidizers.
Four treatments were completed over 5 months, utilizing Propagations, infiltration lateral and vertical injection wells. Post Remediation Results: Soil met meets NJDEP Residential Soil Remediation Standards; Groundwater – No separate phase product; volatile organic compounds and base neutrals were below method detection limits in all wells; No Further Action was issued by the New Jersey of Department of Environmental Protection (NJDEP).
