method's protocol and the requirements of the San Joaquin County PHS-EHD. Accuracy is a measure of <br /> bias in the measurement system, and accuracy of the analytical data will be determined through an <br /> assessment of the recovery of surrogate and spike compounds. Surrogate compounds will be added by <br /> the laboratory to each sample for organic compound analysis, and Ithe percent recovery will be reported <br /> F <br /> with sample results. Reanalysis will be required for samples in which surrogate recoveries are outside <br /> the laboratory-established control limits. All corrective actions taken for'�samples requiring reanalysis <br /> will be reported with sample results. Matrix spike/matrix spike duIplicat&(MS/MSD)compound <br /> recoveries will be reported with sample results. If spike compound recoveries are outside control limits, <br /> then sample reanalysis will be required. All required reanalysis must be performed within method <br /> recommended holding times. Any actions taken tonbring compould recoveries within control limits will <br /> i <br /> be reported by the laboratory in case narratives supplied with sample results. <br /> ij. <br /> 4.0 REPORT PREPARATION <br /> I' <br /> , <br /> 1 � <br /> A site assessment report will be prepared which will present a desc�ription'of the activities performed and <br /> the results of the subsurface soil evaluation. Based upon the information obtained, appropriate <br /> recommendations will be made regarding the findings. The report will b4repared under the supervision <br /> of a California-registered geologist and in accordance with San Joaquin County PHS-EHD requirements. <br /> :k <br /> I� I <br /> IF <br /> 3 � <br /> !` k <br /> !'� I <br /> �f ► <br /> i' <br /> I <br /> a <br /> i% <br /> I <br /> Fi <br /> I� <br /> . i� I <br />
