Challenges

ERFS has completed projects in many industries and locations not listed in our website.  Please inquire about remediation experiences that match your project needs.

Overview of Services

ERFS work all across the United States and Internationally.  Below are some other examples of sites that ERFS has completed.

Vinyl Chloride in Groundwater in Florida:  ERFS installed injection wells in and around a former waste solvent tank bed at this active warehouse facility in Jacksonville, Florida.  ERFS conducted multiple treatments using dilute Fenton-like reagents.  By increasing dissolved oxygen and stimulating microbial activity, ERFS was able to achieve reduction in vinyl chloride from 130 ug/l to <1 ug/l in three months.  The site has been sampled to obtain four quarters of compliant samples and the site owner has been granted closure from FDEP.

No. 4 Fuel Oil in Unsaturated Soils under a high-rise building in Passaic, New Jersey
– No. 4 heating oil LNAPL was delineated in upper soils under and around this 5-story hospital annex apartment building in Passaic.  Site soils consist of dense silt with some clay and sand to 18 ft bgs underlain by siltstone bedrock.  High TPH values were noted in soil samples and open boreholes were observed to collect free flowing LNAPL during sample collection.  Groundwater occurs below the bedrock and is unaffected by the release.  ERFS has installed multiple Propagations across the 20,000 square ft impacted area and conducted multiple oxidizer treatments.  Full closure was granted by the NJDEP.

Bergen County, New Jersey – Mixed Use Site.
 ERFS was retained to remove three buildings and remediate soils and groundwater at a former paint plant, sand blasting center, and oil depot property.  Fuel oil free product had primarily contaminated soil and perched portions of groundwater.  The total petroleum hydrocarbon compounds (TPHC) contamination resulted from a massive spill that occurred in 1960.  The spill resulted from a leak in the 110,000-gallon capacity above-ground storage tank that was located near the southwestern corner of the property.   The actual amount of fuel oil spilled is unknown; however, it apparently saturated the onsite soils in its pathway.  Residual fuel oil was found to be concentrated in lenses of ash associated with historic fill and in a peat layer upon which the ash was deposited.  An On-Contact Remediation Process® program removed all free product, groundwater contamination and completed soil remediation with the following results and achieved closure:
