Superfund Site
A 1,500-square-foot (140 m2) burn pit on the airport property was named a Superfund site on March 31, 1989. The burn pit was built in 1968 and was used until 1979 for firefighter training missions. Jet fuel, gasoline, petroleum storage tank bottoms, fuel oil, kerosene, and sorbent materials from oil spill cleanups were burned in the pit. Up to 500 gallons of fuel and other chemicals were used during each firefighting training exercise. The firefighters in the training missions mainly used water to put out the fires, but carbon dioxide and other dry chemicals were also used. The soil and groundwater was found to have multiple contaminants, including benzene, ethylbenzene, total xylene, 2-methylnaphthalene, phenanthrene, chloroform, 1,2-dichloroethane, and chromium.
When the contamination of the site was discovered, about 500 people live within a mile of the Site. Approximately 6,300 people get their drinking water from public and private wells within three miles of the Site. However, the contamination does not affect current residential populations since the groundwater contamination plume does not extend more than 350 feet from the burn pit.
The site is still undergoing environmental remediation, and the next five year review for the site will be completed in August 2013.

Famous quotes containing the word site:
“It is not menstrual blood per se which disturbs the imagination—unstanchable as that red flood may be—but rather the albumen in the blood, the uterine shreds, placental jellyfish of the female sea. This is the chthonian matrix from which we rose. We have an evolutionary revulsion from slime, our site of biologic origins. Every month, it is woman’s fate to face the abyss of time and being, the abyss which is herself.”
—Camille Paglia (b. 1947)
