Also attached are the <br /> laboratory reports and MW-8 chromatograms for the gasoline and diesel showing the unknown peaks <br /> The compounds detected in the well are unknown VOCs and unknown semi volatiles that are not derived from <br /> gasoline or diesel. <br /> Will over-drilling, instead of pressure grouting, be required for this well? <br /> Thanks, <br /> Tom <br /> Tom Fortner <br /> Senior Project Scientist <br /> Weston Solutions, Inc. <br /> 1340 Treat Blvd., Suite 210 <br /> Walnut Creek CA 94597-7580 <br /> (925)948-2655 <br /> (925)948-2601 FAX <br /> Thomas.Fortner VQ eston_Solutions.com <br /> COMPANY CONFIDENTIAL: This e-mail and attachments may contain information which is <br /> company confidential and proprietary.
