Another method with prior approval by the Water Quality Permitting Section Chief Any method used must meet the following qualifications: a. A laboratory must be DWR certified to run any method used. b. The method used must, at a minimum, include all the constituents listed in Table VIII of Standard Method 6230D. C. The method used must provide a PQL of 0.5 gg/L or less that must be supported by laboratory proficiency studies as required by DWR. Any eonstituents detected above the MDL but below the PQL of 0.5 pg/L must be qualified (estimated) and reported. 5. If any volatile organic compounds (VOC) are detected as a result of monitoring as provided in Attachment C, then the Wilmington Regional Office supervisor, telephone number (910) 796-7215, must be contacted immediately for further instructions regarding any additional follow-up analyses required. 6. If TOC concentrations greater than 10 mg/L are detected in any downgradient monitoring well, additional sampling and analysis must be conducted to identify the individual constituents comprising this TOC concentration. If the TOC concentration as measured in the background monitor well exceeds 10 mg/L, this concentration will be taken to represent the naturally occurring TOC concentration. Any exceedances of this naturally occurring TOC concentration in the downgradient wells shall be subject to the additional sampling and analysis as described above. 7.
