ExxonMobil has used this site since 1928 as a bulk storage facility for many petroleum products. Before 1970, the company discharged petroleum sludges from above-ground storage tanks onto the ground during periodic tank cleanings. Also, the company spilled over 11,000 gallons of unrecovered oil in 1985 (of a total spill of over 40,000).
Thus, the primary contaminant from the site is petroleum, which is contaminating groundwater to levels that exceed federal safe drinking water standards and ambient water quality criteria.
An early cleanup action began in 2004. The chosen remedy included free-product recovery, soil vapor extraction, air sparging, and institutional controls to restrict land use and public access to the site. Efforts to contain contaminants as well as to monitor groundwater are currently underway.
