To provide an economical way to treat DNAPL solvents beneath both active and former dry cleaning facilities.

Overview of Services

ERFS’ financial services are key in making a dry cleaner remediation economical.

Texas Dry Cleaner Example.  Chlorinated solvent contamination at a dry cleaning facility resulting from poor materials-handling practices over many years.  The site had been undergoing site investigation activities for 4 years and was entered into the Texas Voluntary Cleanup Program.  Risk-based cleanup goals for the site were established at 5ug/L for PCE, TCE and DCE.  Subsurface soils at the site consist of approximately 7 to 9 feet of clay with abundant fine angular gravel and trace amounts of fine sand, followed by 7 to 9 feet of clay containing abundant fine to medium angular pebbles.  Bedrock was encountered at approximately 16 to18 feet below grade.  Bedrock is described as massive chalk, with some interbeds and partings of calcareous clay. ERFS completed 2 other dry cleaner remediations for the same owner concurrently in the Dallas area.


Contaminant levels in parts per billion



New Jersey Dry Cleaners – ERFS conducts Pay-for-Performance cleanups at dry cleaning facilities in New Jesery.  One project involves treat impacted soils and groundwater around large utility conduits.  Site soil is described as silty sand with saturated conditions approximately 4 ft bgs.  Following limited soil removal, treatment began using catalyzed peroxide followed by iron and peroxide initiated sodium persulfate.  Unsaturated soils have been treated from starting concentrations ranging from 10 mg/kg to 46 mg/kg in multiple locations.  Regulatory action levels for closure were completed.

Florida Dry Cleaner
– ERFS assisted with Remedial Action Plan preparation and approval, installed Propagations and vertical injection points, and conducted multiple peroxide treatments with catalyzed hydrogen peroxide to achieve 70% CVOC reduction.  Midway through the project, the site owner discovered a former lint trap with CVOC impacted sludge within and impacted soil beneath it.  After removing the lint trap and excavating impacted soil, the owner installed a source area monitoring well.  ERFS subsequently resumed groundwater treatment and added supplemental injection wells; ultimately achieving 99.8% source area groundwater reduction and completing the project.
