Site Details

A brief history

The site is currently being used as a retail gas station with an automotive repair shop. Soil impact was first observed onsite in 2001 during the removal and replacement of four dispensers and the associated piping. Groundwater impact was confirmed in 2002. 

 

Proposed Remediation Plan

The current development remediation includes the injection of persulfate into the groundwater to enhance the anaerobic bioremediation of the petroleum related constituents of concern. Persulfate is activated by heat, alkaline agent, or transition metals. Once activated, sulfate radicals are released which are highly reactive and capable of oxidizing organic contaminants. The oxidation process helps to convert hydrocarbon compounds from the gasoline-related contaminants into simpler, more biodegradable chemicals. Groundwater will be sampled periodically after the injections are completed to assess the degradation of the residual petroleum hydrocarbon compounds.
