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.
If TOC concentrations greater than 10 mg/1 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/1,
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.
The results of the sampling and analysis must be received on Form GW-59 (Groundwater Quality
Monitoring: Compliance Report Form) by the Groundwater Section, Permits and Compliance Unit, 1636
Mail Service Center Raleigh, N.C. 27699-1636 on or before the last working day of the month following
