For analytical methods from EPA SW-846, EPA 60014-79-020, or <br /> Standard Methods, the laboratory will follow any calibration procedures listed for the <br /> particular method. The laboratory's Standard Operating Procedures ry p g dares are available upon <br /> request. . <br /> it k <br /> i B.3 Analytical Procedures 1 <br /> All soil and water analyses will be performed by a state approved] aboratory. All analytical <br /> procedures employ EPA approved methodology. <br /> B.4 Data Reporting, Validation, and Reduction <br /> Data handling practices will ensure raw data validity and provide 'an audit trail for data that <br /> require reduction. The following sections describe procedures for afield and laboratory data <br /> validation, data reduction, documentation control, and data flow. '6 i <br /> B.4.I Field Data Validation <br /> The field team will enter field data (instrument calibrations,:'measurements, observations, <br /> etc.) into field log books and data sheets. Field personnel will make all information entries <br /> �f <br /> in water-resistant ink. Field personnel will record into the field activity log books sufficient <br /> information to reconstruct each sampling it event, including: <br /> 808-001.wkp103-14-971ulkeydaalworkplan B-6 <br /> 1 <br /> r <br />
