Petersborough, NH – GZA GeoEnvironmental Inc. recently completed a successful groundwater remediation project at a Petersborough service station using a proprietary bioremediation formula developed by the company.
A release from a leaking underground gasoline storage tank system at the service station had caused the groundwater to be contaminated with fuel hydrocarbons. The new, innovative “green” technology was able to reduce a significant amount of the contamination to the groundwater.
GZA’s work scope included: hydrogeologic site investigation, remedial options evaluation and design, and a remedial pilot study of the patent-pending technology. During the course of a seven-week pilot test, and subsequent follow-up 10 months later, this proprietary additive was proven to have destroyed a bulk of the contamination and increased the pH and, as a result, the microbial metabolism and groundwater quality .
Don Kirkland, the GZA project manager for this site, states, “The additive is a sustainable and “green” remedial option for petroleum-impacted sites, with the end products generally being water, carbon dioxide, innocuous gas, and microbial biomass.”
