Charter Way, Stockton <br /> Dear Mr Weiss; <br /> As I mentioned on the phone earlier, 4 auger holes & 4 monitoring <br /> wells were placed on the above property on July 5 & 6 using MDE <br /> rig & equipment . All work was done under my direct supervision, <br /> assisted by Don Light of Del-Tech Geotechnical Support . The <br /> laboratory results, water level measurements & survey data have <br /> finally been received, and we are in the process of preparing a <br /> report covering the activities . However, due to an extremely <br /> heavy workload, that report may not be finished for several <br /> weeks . In order for you to review some of the data derived from <br /> that work, we are including the following "rough" documents for <br /> your review: <br /> . 1 . Field logs of auger holes A, B, C, & D <br /> 2 . Field logs of monitoring wells I, 2, 3 , & 4 <br /> 3 . Well completion diagrams of the four monitoring wells <br /> 4 . Tables VIII, IX, X, & XI summarizing the laboratory results <br /> of soil & water samples . <br /> 5 . A portion of the site map showing locations of the auger <br /> holes and monitoring wells, casing elevations, depth to water, <br /> (MSL datum, ) contours on the top of the water table, and the <br /> hydraulic gradient indicated from that data <br /> Preliminary maps of lines of equal concentrations of THP-G, TRPH <br /> as diesel, and BTEX suggest a possible source of contamination to <br /> the south and west . Those maps will be included with the final <br /> report when finished. <br /> We are planning on uncovering and sampling the unused clay <br /> "mystery" line that parallels the west property line in an <br /> attempt to determine what it was used for. The results of that <br /> work will also be included in the report . <br /> If you have any questions concerning the material we have <br /> furnished you, please contact our office at your convenience <br /> Sinc 1 <br /> Wm unter & Associates <br /> cc, W.
