Problems/Comments

Site first known to be contaminated on 8/30/1991 in site assessment sampling by Randolph Bayliss, P.E. contracted under the previous owner, K&J Auto. The underground tanks, related equipment and some of the soil contaminated by the fuel release were removed from site in April 1992 by the Mountain Corporation. Gasoline soil contamination beneath Third Avenue was deemed not accessible and was left in-place. In 2001, four monitoring wells were installed to investigate gasoline contamination migrating in groundwater beyond Third Avenue. In 2003, 60 cubic yards of gasoline contaminated material was removed from the ditchline on the south side of Third Avenue. An air sparging unit was installed along 50 feet of the facility side ditchline of Third Avenue. The Mountain Corporation operates the sparging unit several hours every day, delivering air into the subsurface environment to promote bacterial breakdown of primarily gasoline and benzene contamination residing in the soil and groundwater.
