The site is currently occupied by Inland Paint Company. One 1,000-gallon <br /> underground storage tank was located on site in back of the building. In March 1990, the storage <br /> tank, all associated piping, and fuel dispensers were removed from the ground and disposed of off <br /> site. Soil samples were collected from beneath the underground storage tank. Laboratory <br /> analysis of-the samples indicated that the soil was contaminated with gasoline. The hole where ' <br /> the tank was located was filled up with dirt. <br /> RECENT SITE WORK <br /> On January 8, 1998, ATC Associates drilled one soil boring to 41.5 feet -below ground surface <br /> (bgs). Soil samples were collected and analyzed by a laboratory. The results of the analysis <br /> indicated the soil was contaminated with gasoline. Most of the contaminated soil was in the top <br />' ten feet of dirt. The soil loWer than ten feet was significantly less contaminated. When <br /> groundwater was encountered, at approximately 40 feet bgs, a groundwater sample was collected <br /> and analyzed by a laboratory. The results of the analysis indicated the groundwater was <br /> contaminated with gasoline. After all samples had been collected, the hole was filled to the <br />' surface with neat cement. <br /> REMEDIATION PLAN <br /> I� To try and cleanup the majority of the contaminated soil, ATC proposes to excavate the soil in the <br /> area where the underground storage tank used to be located. The top ten feet of soil will be dug <br /> up and any soil that is visibly contaminated will also be dug-up. The contaminated soil will be dug <br /> up and transported the same day it is excavated to an appropriate off site disposal facility <br /> I' (landfill). The hole will then be filled up with clean soil and compacted. All work will be <br /> completed in.one day. By removing the majority of the contaminated soil, we will help prevent <br /> the groundwater from_getting more contaminated. <br /> r <br /> ' E <br /> f <br /> k <br /> I <br /> I <br />
