| 5/3/2007 | Site Visit | Site visit by ADEC staff Oelkers and Williams. Met with retired employees Dave Kelly house and Danny Grandgren who were on-site during the tank removal. Determined that on-site DW well is within 100 feet of the former excavation. Depth to GW is between 40 and 90 feet. DW well established in 1955 and depth is unknown. The installation date for the tank and dispenser are also unknown, however tank had been out of service since the mid-1980's when it was pulled in 1997. The tank held gasoline since the early 1970's. | Shannon Oelkers |
