` KLEINEELDER 6. Sample Collection and Handling rr. The stainless steel hand auger and sample tubes were cleaned with a Liquinox® (laboratory-grade detergent) wash followed by a potable water and distilled water rinse. The stainless steel tubes used for collecting the samples were then sealed following L collection of the sample with Teflon® sheeting and tight-fitting plastic end caps. The glass jars were simply capped with provided lids. After collection, the soil samples were labeled, logged on a chain-of-custody form, and immediately stored in an iced cooler rw pending transportation to the analytical laboratory. The soil samples were transported under chain-of-custody control to Kleinfelder's office to and then transported by courier in a chilled container to California Laboratory Services (CLS) of Rancho Cordova, California. The chain-of-custody form was signed by each individual who handled the samples, including the sampler and the receiving employee at CLS. CLS is certified by the State of California to perform the analyses requested. The samples were analyzed on an standard 10 working day turnaround schedule for completion. ANALYTICAL RESULTS r. A total of eight discrete soil samples were collected and submitted for the following analyses: Total Extractable Petroleum Hydrocarbons as referenced to diesel, motor oil, hydraulic oil, mineral oil and kerosene by EPA Method 8015M Benzene, toluene, ethylbenzene, xylenes [BTEX] by EPA Method 8021 B The analytical reports showed that all eight soil samples were none detected at or above laboratory reporting limits for the requested petroleum compounds. A copy of the ` chain-of-custody and laboratory analytical sheets are located in Appendix B. ` CONCLUSIONS AND RECOMMENDATIONS The following conclusions and recommendations are based upon analytical results and Kleinfelder's findings: 1. No unusual odors or soil discoloration was noted in the test pits or during soil ` sampling conducted in proximity to the locations of five asphalt UST, Nos. 1 through 5, located at the site (see Plate 3). f` bp 90161T031ST07R1061 January 3,2008 0 2007 Kleinfelder Page 4 of 7
