Application of an In Situ Bioremedy Biobarrier at a Retail Gas Station
Located in western Connecticut, this site has been in use as a gas station since 1950. It is situated in a mixed commercial and residential area and is now operating as a retail gas station and convenience store. The site rests on fairly flat ground with a slight northwest topographic grade toward the Pomperaug River. Bedrock underlies the site approximately 12 meters (40 feet) bgs and drops to more than 60 meters (200 feet) bgs to the northwest. The un-consolidated material above the bedrock is stratified drift consisting of fine to coarse sand with silts, gravels, and cobbles. A dense cobble-rich layer was encountered at approximately 4 meters (14 feet) bgs beneath the site.
