of casing) of all monitoring wells shall be surveyed relative to a common datum.
4. Volatile Organic Compounds (VOC) - In February only, analyze by one of the following methods:
a. Standard Method 6230D, PQL at 0.5 µg/L or less
b. Standard Method 621 OD, PQL at 0.5 µg/L or less
C. EPA Method 8021, Low Concentration, PQL at 0.5 µg/L or less
d. EPA Method 8260, Low Concentration, PQL at 0.5 µg/L or less
e. 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 Vill of Standard Method 6230D.
c. The method used must provide a PQL of 0.5 µg/L or less that must be supported by laboratory proficiency studies as required by DWR. Any constituents detected above
the PQL of 0.5 µg/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 Mooresville,Regional Office supervisor, telephone number
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. Upon receipt of notification from the division to resume monitoring for VOCs.
8. Monitoring wells shall be reported consistent with the nomenclature and location information provided in Figure 2 and this attachment.
