Carollo EngineersGao <br /> November 21,2006(Project No. 3045.036) <br /> The groundwater samples for the volatile organic compound (VOC) analyses will be collected in <br /> three, 40-milliliter glass containers, preserved with HNO3, and analyzed in accordance with <br /> EPA Test Method 8260 within 14 days. <br /> Field Parameter Units <br /> Groundwater Elevation 0.01 ft, MSL <br /> Temperature degree C <br /> Either STL (ELAP #2496) of Pleasanton, California, or Advanced Technology <br /> Laboratories (ELAP#1838) of Signal Hills, California, will perform the chemical analyses for this <br /> project. <br /> Fugro follows the standard chain-of-custody procedures for sample conveyance. A <br /> chain-of-custody form accompanies the samples at all time. One person is responsible for the <br /> samples, and he accepts this responsibility by signing the chain-of-custody form when he <br /> receives the samples. When he relinquishes control of the samples, he again signs and the <br /> next responsible party also signs the chain-of-custody form to identify his acceptance of the <br /> responsibility. In this manner, Fugro tracks the integrity of each sample from the time it is <br /> collected to its delivery to the chemical laboratory. <br /> In order to evaluate the quality of the data from the monitoring of the well, the field crew <br /> will collect one duplicate sample from one well for each round of sampling. The field crew will <br /> decontaminate all sampling equipment before reuse and collect one sample from the final <br /> rinsate of the sampling equipment that is generated during decontamination. The duplicate and <br /> rinsate samples will be analyzed for the VOC analyses only. <br /> 4.0 PROPOSED SCHEDULE <br /> Fugro anticipates that the CVRWCCB will complete their review of the Sampling and <br /> Analysis Plan in December 2006 and provide their approval to proceed. The California <br /> Department of Corrections and Rehabilitation will select a Contractor to construct the brine <br /> ponds and to install the three monitoring wells in 2007. If needed, the field crew will also install <br /> the fourth groundwater monitoring well in 2007. <br /> G'.U0 <br /> BOCLS13095�92i50WIN&O SWT-21NOWQ 5 <br />
