Due to heavy truck traffic in the area of <br /> the fueling island facility at the subject site, the monitoring well designated UST-1 has been <br /> damaged and should be properly abandoned. Three monitoring wells designated UST-2, UST-3 <br /> and UST-4 that were installed around the subject fueling island facility in early April 1995 and <br /> would be utilized to continue the monitoring of the subsurface conditions. A brief description. <br /> of the abandonment procedure is given below. <br /> The scope of work for the abandonment of monitoring well UST-1 is to pressure grout the 4" <br /> diameter well to its depth of 103 feet below ground surface. The top 30 feet of PVC casing will <br /> be drilled out, and the boring grouted to the surface. All well debris will be drummed. The <br /> licensed driller selected for the abandonment is Spectrum of Stockton.
