I <br /> Project No. 034-00009 <br /> Page No.2 <br /> FIELD INVESTIGATION <br /> Krazan personnel accessed the on-sit Ie well by cutting the existing lock. The well was sounded using a <br /> device to determine the depth of the well and the depth to groundwater within the monitoring well. <br /> Based on the measurements, the total water volume of the well was calculated and three volumes were <br /> purged using a pre-cleaned bailer prior to sampling in order to obtain a representative groundwater <br /> sample. Purge water was placed in;a 55-gallon drum that was labeled, sealed, and stored on site. A <br /> single water sample was then collected from the well. The sample was collected by lowering a <br /> disposable polyethylene bailer into the well. The sampled groundwater was then transferred to <br /> laboratory-supplied containers specific for the anticipated analyses. The sample was labeled with the <br /> sample number, collection date, and project number and retained on ice in an insulted chest pending <br /> delivery to the laboratory. Chain-of-custody (COC) procedures were used to document the'handling and <br /> transport of the sample from the time the sample was collected to the time it was delivered to the <br /> laboratory. The work was performed under the supervision of a California-registered professional <br /> geologist from Krazan. <br /> ANALYTICAL RESULTS <br /> The groundwater sample was submitted to SunStar Laboratories, Inc., of Tustin, California, a state- <br /> certified analytical laboratory, for analysis of total petroleum hydrocarbons (TPH) gasoline and diesel; <br /> benzene, toulene, ethylbenzene, and total xylenes(BTEX); methyl tertiary butyl ether(MTBE); and total <br /> lead in accordance with Environmental Protection Agency (EPA) Methods 8015(modified), 8020, and <br /> 6010. These constituents were not detected at or above the respective laboratory reporting limits. A <br /> copy of the laboratory analytical report and the COC form is attached. <br /> e <br /> If you have any questions or if I can be of further assistance, please feel free to contact me at(916) 564- <br /> 2200. <br /> Respectfully submitted, <br /> KRAZAN &ASSOCIATES,INC. <br /> Cath L, Rbed <br /> Y <br /> Environmental Specialist <br /> Douglas Sheeks <br /> Senior Geologist <br /> CRG No. 5211 <br /> CLR/DIS/clr r <br /> Attachments <br /> KRAZAN&ASSOCIATES,INC. <br /> Offices Serving the Western United States <br /> 3400009.1rt.doc <br /> I <br /> 41, ___ <br />
