q.. <br /> that it is not inadvertently used, and the appropriate personnel notified so that a recali- <br /> bration can be performed or a substitute piece of equipment can be obtained. <br /> Equipment that fails calibration or becomes inoperable during use will be removed <br /> from service and either segregated to prevent inadvertent use or tagged to indicate it is <br /> out of calibration._. Such equipment will be repaired and satisfactorily recalibrated. <br /> Equipment that cannot be repaired will be replaced. <br /> — Results of activities performed using equipment that has failed recalibration will be <br /> evaluated. If the activsty results are adversely affected,the results of the evaluation will <br /> be documented and the appropriate personnel notified. <br /> Calibration instructions will be included with each instrument and will accompany the <br /> instrument to the field. <br /> 4.6 ANALYTICAL PROCEDURES <br /> Lab-specific method and target detection limits are the same for this study. All <br /> sampler;will be analyzed using EPA- and California-approved procedures as shown in <br /> Table 3-1 in Section 3. <br /> i <br /> 4.7 INTERNAL QUALITY CONI'R.OI. <br /> The field sampling team leader will be responsible for ensuring that the field QA sam- <br /> ples are collected. Duplicate soil samples will be collected to check for variability in <br /> soil parameter levels. When a duplicate sample is needed, two brass sleeves or two i <br /> + , glass jars of the soil sample will be submitted for analysis; one will be the sample and <br /> the other the duplicate. <br /> A duplicate water sample will be collected to check for variability in Iaboratory analy- <br /> ses. A field blank will also be collected and analyzed for volatile organic compounds. <br /> Lij <br /> Z <br /> sF031604XwP)004.51 4-14 <br />
