Grant Line Rd. Tracy <br /> Hi Vicki, <br /> As I suspect you have heard from Johnny Yoakum,we were unable to destroy four of the monitoring wells <br /> at the former Food & Liquor 15 E. Grant Line Rd.Tracy. <br /> Three of the monitoring wells(MW1, MW3,and MW4)were constructed with a what appears to be a <br /> conductor casing which prevented their overdrilling that were not reflected on the well logs. In addition, <br /> the two other wells had physical obstructions that prevented the placement of the drill rig over the <br /> wells. MW1 was obstructed by a tree and MW2 was obstructed by a block wall. Please see the attached <br /> pictures from the site. <br /> We have been working with the driller,Woodward Drilling,to come up with a potential solution to the <br /> issues, and want to get your input. <br /> Due to the relatively short, 5-foot long well seals in the affected wells,we are proposing to use an air <br /> knife to remove the soil encircling the well box and well seal, down to the end of the well seal,—5-feet <br /> bgs. The original boring logs show each of the wells have a 5-foot long well seal.After removing the <br /> supporting soil,we are proposing to cut the casing at the base of the well seal, and hoist the well box and <br /> well seal out of the ground as a complete unit, leaving the casing in place in each of the four wells.
