Attached to this <br /> report are a site map, chemistry sheets and a copy of the chain-of- <br /> custody documentation. The scope of our testing was initiated per <br /> the verbal authorization of Mr. George Muzio with PG&E. <br /> SCOPE OF WORK <br /> Services performed by The Twining Laboratories Inc. (Twining) <br /> consisted of the sampling and analysis of three soil samples during <br /> removal of a 2, 000 gallon UST identified as Tank No. 4 . The <br /> storage tank had a product history of diesel fuel . Soil sample No. <br /> 1 was retrieved from the stockpiled soil that was removed during <br /> UST removal . Soil sample No. 2 was obtained from below the west <br /> end; and sample No. 3 was obtained from below the east end of Tank <br /> No. 4 . Soil sample Nos . 2 and 3 were obtained at a depth of 9 to <br /> 11 feet below site grade (BSG) . <br /> The tank was rusty and pitted. However, no holes in the tank, <br /> or soil discoloration was noted in the excavation. The approximate <br /> location of the former storage tank is presented on Drawing No. 1 . <br /> SAMPLING PROCEDURE <br /> The soil samples were obtained by Mr. Ray Kurz of Twining on <br /> January 30, 1992 . Sample No. 1 was obtained from the stockpiled <br /> soil by hand auguring to a depth of two feet below surface. Soil <br /> samples No. 2 and 3 were obtained approximately two feet below the <br /> ❑ 2527 Fresno Street•P.O.Box 1472 ❑ 9401 West Goshen Avenue <br /> Fresno,California 93716 Visalia,California 93291 <br /> (209)268-7021 •Fax(209)268-7126 (209)661-2190•Fax(209)651-2654 <br /> ❑ 4230 Kiernan Avenue,Suite 105 ❑ 3701 Pegasus Drive,Suite 124 <br /> Modesto,California 95356 Bakersfield,California 93308 <br /> (209)545-1050•Fax(209)545-1147 (80,91393-5088• Fax(805)393-4643 <br />
