1. 3 Xlyear monitoring shall be conducted in March, July and November.
2- The measurement of water levels shall be made prior to purging the wells. The depth to water in each well small 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. If TOC concentrations greater than 10 mgll 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 mgll, 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.
5. Volatile Organic Compounds (VOC) - In November only, analyze by one of the following methods:
a. Standard Method 6230D, PQL at 0.5 pg/L or less
b. Standard Method 621 OD, PQL at 0.5 pg1L or less
G. EPA Method 8021, Low Concentration, PQL at 0.5 ftg/L or less
d. EPA Method 8260, Low Concentration, PQL at 0.5 pg1L or less
e. Another method with prior approval by the Aquifer Protection Section Chief
Any method used must meet the following qualifications:
a. A laboratory must be DWQ certified to run any method used.
b. The method used must, at a minimum, include all the constituents listed in Table VIII or Standard Method 6230D.
c. The method used must provide a PQL of 0.5 }rg/L or less that must be supported by laboratory proficiency studies as required by the DWQ Laboratory Certification
Unit. Any constituents detected above the MDL but below the PQL of 0,5 Ng/L must be qualified (estimated) and reported.
If any volatile organic compounds (VOC) are detected as a result of monitoring as provided in Attachment C, then the Wilmington Regional Office Aquifer Protection
Section Supervisor, telephone number [phone], must be contacted immediately for further instruclinns regarding any additional follow-up analyses required.
Monitoring wells shall be reported consistent with the nomenclature and location information provided in Figure 2 and this attachment.
