The measurement of water levels shall be made prior to purging the wells. The depth to water in each well shall be measured from the surveyed point on the top of the casing. The measurement of pH shall be made after purging and prior to sampling for the remaining parameters. 3. The measuring points (top of well casing) of all monitoring wells shall be surveyed to provide the relative elevation of the measuring point for each monitoring well. The measuring points (top of casing) of all monitoring wells shall be surveyed relative to a common datum. 4. Volatile Organic Compounds (VOC) - In November only, analyze by one of the following methods: a. Standard Method 6230D, PQL at 0.5 gg/L or less b. Standard Method 6210D, PQL at 0.5 �ug/L or less c. EPA Method 8021, Low Concentration, PQL at 0.5 gg/L or less d. EPA Method 8260, Low Concentration, PQL at 0.5 gg/L or less e. Another method with prior approval by the Water Quality Permitting Section Chief Any method used shall meet the following qualifications: a. A laboratory shall be DWR certified to run any method used. b. The method used shall include all the constituents listed in Table VIII of Standard Method 6230D. c. The method used shall provide a PQL of 0.5 gg/L or less that shall be supported by laboratory proficiency studies as required by the DWR Laboratory Certification Unit. Any constituents detected above the MDL but below the PQL of 0.5 gg/L shall 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 Washington Regional Office supervisor, telephone number (252) 946-6481, shall 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 shall 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. Monitoring wells shall be reported consistent with the nomenclature and location information provided in Figure 1 and this attachment.
