Per our conversation,we would like a 30 day extension to <br /> the August 8, 2011 deadline to"submit a work plan to continue to characterize the groundwater plume emanating <br /> from the site"requested in the letter dated June 8, 2011 from the San Joaquin County Environmental Health <br /> Department. <br /> After discussions with Shell's consultant, Conestoga-Rovers &Associates, it appears that new data will be <br /> available shortly from borings conducted between the two sites that may assist in delineating the contaminant <br /> plume in this area. The 30-day extension will allow for additional time for Stantec to acquire the new data and <br /> review it for relevance. <br /> Additionally, Stantec was able to utilize a down hole video camera on monitoring well MW-1S to determine the <br /> nature of the blockage in the well on June 28, 2011. The video revealed a thin gauge plastic pipe in the well just <br /> above the water surface which appears to be a disposable bailer with the top removed. To clear the blockage we <br /> are planning on subcontracting a vacuum truck to attempt to suck it out. Following successful removal of the <br /> blockage the down hole video camera will again be used to verify the integrity of the well. Stantec will follow up <br /> with SJCEHD regarding all field activities promptly. <br /> Thank you, <br /> Brad Shelton,P.G. <br /> Associate Geologist <br /> Stantec <br /> 3017 Kilgore Road Suite 100 <br /> Rancho Cordova CA 95670 <br /> Ph: (916)861-0400 <br /> Fx: (916)861-0430 <br /> Cell: (916)225-3800 <br /> brad.shelton@stantec.com <br /> stantec.com <br /> The content of this email is the confidential property of Stantec and should not be copied,modified,retransmitted,or used for <br /> any purpose except with Stantec's written authorization.
