Laboratory Quality Control Procedures <br /> Laboratory quality control procedures will include those required under the OEHHA <br /> Hazardous Waste Testing Program Specific laboratory quality assurance <br /> procedures are included in the laboratory's QA/QC manual, including reporting <br /> surrogate recovenes, matrix spike recoveries, and matrix spike duplicates (or <br /> duplicate) results <br /> Method blanks will be <br /> analyzed daily to assess the effect of the laboratory <br /> environment on the analytical results Method blanks will be performed for each <br /> parameter analyzed <br /> ' Each sample to be analyzed for organic parameters will contain surrogate spike <br /> compounds The surrogate recovenes will be used to determine if the analytical <br /> instruments are operating within limits Surrogate recovenes will be compared to <br /> control limits established and updated by the laboratory based on its historical <br /> operation <br /> Matrix spikes will be analyzed at a frequency of approximately 10 percent Matrix <br /> spike results will be evaluated to determine whether the sample matrix is interfering <br /> with the laboratory analysis and to provide a measure of the accuracy of the <br /> analytical data Matrix spike recovenes will be compared to control limits <br /> established and updated by the laboratory based on its historical operation <br /> ' Laboratory duplicates will be analyzed at a frequency of approximately 10 percent <br /> Spike duplicate results will be evaluated to determine the reproducibility (precision) <br /> of the analytical method Reproducibility values will be compared to control limits <br /> established and updated by the laboratory based on its historical operation <br /> Laboratory QA/QC data will be included with the analytical results This QA/QC <br /> data will include method blanks, surrogate spike recovenes (for organic parameters <br /> only), matrix spike recovenes, and matrix spike duplicates <br /> Field Screening of Hydrocarbon Contaminated Water and Soil <br /> ' HNU-Handby Environmental Test Kilt <br /> Soil and water analysis may be carried out in the field with typical minimum <br /> detection levels for BTEX, unleaded gasoline, diesel fuel and crude oil of 1 ppm in <br /> soil and 100 ppb in water Detailed protocol is included with the test kit In general <br /> C- 10 <br />
