In Situ Ozone Remediation of Gasoline and TPH | Various, New Jersey/Pennsylvania/Rhode Island/New Hampshire/New York/Florida
The prior owner of a large tract of land, located in a lakefront development area, had liability under NYS Navigation Law to remediate soil and groundwater affected by petroleum hydrocarbons. Another consulting firm was attempting remediation by various methods. To facilitate sale of the property, BLUE was contracted to implement an ozone injection remedy at this site.
An existing 380-foot-long horizontal well was utilized to inject ozone and compressed air into the area of concern. Saturated and unsaturated soils, and contaminated groundwater, were exposed to ozone injection and total phase extraction was operated simultaneously. The ozone injection system was operated for seven months. Sampling at completion of this seven month period indicated a 97% reduction of VOC concentrations in soil, a 64% reduction of VOC concentrations in groundwater, and reductions of MTBE in soil and groundwater of 90% and 45%, respectively. The client was able to work with the property owner and developer to move the project into the redevelopment phase after completion of the ozone remedial action.
In addition to the above case summary, BLUE has remediated and is currently conducting remediation at service stations throughout New Jersey, Pennsylvania, Rhode Island, New York and Florida. As a service provider for several gasoline distribution companies, BLUE RemedO3Zone™ solutions have been utilized to remediate various levels of petroleum releases and achieved site closure.
