s w f T FOX ENVIRONMENTAL ERVICES, INC. 8015 West Cliff Drive • Knoxville, TN 2 7919 • (61 51 690-1 996 July 2, 1985 Mr. Kelly Williamson RE: Fast Gas Station Kayo Oil Company Highway 12 1221 E. Main Street Lodi, CAL Chattanooga, TN Dear Mr. Williamson: On June 21, 1985 a monitoring visit was made to the Fast Gas Station, located at the corner of Highway 12 and Lower Sacramento Rd. Additional monitoring visits were conducted on June 2 and June 24, 1985. There are 13 monitoring wells in place at this location, but only four of these wells are into the ground water, thus, for the sake of the report only these four wells will be addressed. j A plot plan of this facility is attached, mhich indicates the location f of wells, along with a chart of the well data that was recorded at the + dates and times indicated. Monitoring wells #MW 10 and MW 13 are located to the rear and to the south west side of the property, respectively. Both of these wells had measureable amounts of product on the ground water surface, and after measurements were taken and bail downs performed, both wells recharged with significant quantities of product. Monitoring wells MW 11 which is located across Lower Sacramento Rd. and MW 12 which is located in the right of way of Highway 12 on the North east corner of the property were void of any visible signs of product or odor. It would seem obvious that there is a plume of product on the ground water at this location, but the true extent of this plume cannot be defined with the limited number of usable monitoring wells now in place. Several approaches can be considered at this time with regard to remedi- ation and herewith are twu. The first approach would be to install a recovery well somewhere between. MW10 and MW 13 and institute recovery procedures using MW 10 and MW 13 to assess recovery' progress as related to ground water condition. A second approach would be to install monitoring wells off site to the west
