Mattu [EH] <br /> Subject: FW: 500 East Louise Avenue <br /> Attachments: 1504123.PDF; 1504124.PDF; Former PNA-Lathrop Trenching Plan 042015.pdf <br /> Mr. McCellon: <br /> AGE has received the soil sample analytical data from the trenches and soil piles from the SWIS site <br /> at 500 East Louise Avenue in Lathrop. <br /> Attached is the site plan and raw analytical data from the investigation. As noted most every trench (T <br /> samples) were analyzed for metals, most for pH and others for VOC and other chemicals. No much of <br /> any were detected. The soil piles samples (S samples) were also analyzed at your offices request. <br /> Most soil piles were non detected for VOC and other chemicals. One location did have elevated <br /> metals, however this set of piles would be profiled for local disposal at Forward Landfill. Map of the <br /> trenches attached. <br /> Minor volumes of debris were observed in the trench section, typically at depths of four feet or three <br /> feet, with a thickness horizon of less than six to eight inches. AGE found no big items or locations <br /> without the presents of a native soil base under the spilled glass waste. Glass was the majority of the <br /> waste, with some bit or strings of plastic excavated. This section is what was observed in the <br /> Geoprobe soil boring logs (photo attached next email). <br /> AGE plans to backfill the excavation with a soil mix borrowed from the field east of the former SWIS <br /> area. I will inform your office. <br /> Additionally the soil will piled and profiled for disposal/landfill. <br /> William Little <br /> California Professional Geologist#7473 <br /> Advanced GeoEnvironmental, Inc. <br /> Environmental - Industrial Hygiene - Geotechnical - Contracting <br /> Phone: 800-511-9300 <br /> Fax: 888-445-8786 <br /> wlittleCa)-advgeoenv.com <br /> www.advgeoenv.com <br /> This email/fax message is for the sole use of the intended recipient(s) and may contain confidential <br /> and privileged information.
