LEVINE•FRICKE <br /> method 7060) , and copper (EPA method 6010) . The anticipated <br /> detection limits for arsenic and copper are 0.50 and <br /> 1. 25 parts per million (ppm) respectively. Detection limits <br /> for VOCs analyzed under EPA method 8010 will range from 0.0005 <br /> to 0. 001 ppm depending on the parameter. These anticipated <br /> detection limits may vary due to soil matrix interferences. <br /> DTSC Comment 2: Levine-Fricke anticipates submitting a total <br /> of 30 to 35 soil samples for chemical analysis. Therefore, <br /> three duplicate soil samples will be submitted for each <br /> analytical method to monitor the laboratory quality assurance <br /> and quality control procedures (QA\QC) . In addition, <br /> laboratory reports will include results of the internal <br /> laboratory QA\QC procedures (i.e. matrix spikes and method <br /> blanks) . <br /> DTSC Comment 3 : To meet the recommended holding times for <br /> soil samples analyzed for VOCs, the soil samples collected and <br /> held pending analysis of shallower samples will be analyzed on <br /> a rush turnaround basis, if necessary. Metals analyses can be <br /> done on normal turnaround since holding times exceed 14 days. <br /> DTSC Comment 4: Analytical methods for soil samples collected <br /> from fine-grained intervals identified by continuous cores <br /> will be analyzed for VOCs (EPA method 8010) , arsenic (EPA <br /> method 7060) , and copper (EPA method 6010) , depending on the <br /> location of the soil boring. <br /> Soil Sample Analysis Rationale: <br /> DTSC Comment 1: As indicated on Figure 2 of the Work Plan, <br /> soil samples collected in the vicinity of the former ultra <br /> etch storage area will be analyzed for VOCs (using EPA method <br /> 8010) , arsenic, and copper. <br /> Well Drilling, Installation, Construction, Development, <br /> and Sampling <br /> A ground-water monitoring well will not be installed as part <br /> of this investigation. <br /> 2617\2617CMTS:uIk 3 <br />
