Physical Treatment at a New Hampshire Site
In response to a sudden release of RFG from a UST in late September 1996, emergency response actions and assessment activities were completed. Ultimately, a combined ground water recovery and SVE system was installed and operated for a period of four years. As a result of source removal and physical treatment of soil and ground water, an estimated total of 5,118 kilograms (11,282 pounds) or 6,833 liters (1,805 gallons) of petroleum hydrocarbons were recovered from beneath the site. The site is currently in a natural attenuation and limited enhanced bioremediation program consisting of tri-annual sampling and periodic microbe and nutrient addition. This site demonstrates that conventional technologies and strategies are effective for remediating gasoline constituents, including MTBE.
