In our workplan addendum,we had recommended <br /> that the well have its contents drilled out entirely due to some low levels of residual <br /> groundwater contamination. In the time since the installation of the well in 1995, a decorative <br /> stone wall/sign was installed directly adjacent to the well (see the attached pictures). I have <br /> discussed the location of this well with the operator of my drilling company's limited access <br /> drilling rig and we both agree that there is no way to safely set up and operate a drilling rig at <br /> this location.As an alternative,we are willing to pressure grout the well holding Portland <br /> cement under 25 psi for 10 minutes. Following that we will install a mushroom cap as explained <br /> in our workplan addendum with the sole exception being that we will over excavate this well to <br /> 5 feet instead of 3 feet. If you feel that this is acceptable, please let me know so that I may make <br /> the suitable arrangements. <br /> Thanks, <br /> oil -Josh Ewert I Senior Staff Geologist <br /> Geocon Consultants, Inc. <br /> 3160 Gold Valley Drive Suite 800, Rancho Cordova, CA 95742 <br /> Tel 916.852.9118 Fax 916.852.9132 <br /> www.ge..oconmc_corn <br /> 1/31/2012 <br />
