(3) 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 the DWQ Laboratory Certification Unit. Any constituents
detected above the MDL but below the PQL of 0.5 µg/L must be qualified (estimated) and
reported.
The measurement of water levels must be made prior to sampling for the remaining parameters. The depth
to water in each well shall be measured from the surveyed point on the top of the casing.
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 I0 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.

If any volatile organic compounds are detected by Method 6230D, then the Wilmington Regional Office
Groundwater Supervisor, telephone number [phone], must be contacted immediately for further
instructions regarding any additional follow-up analyses required. The results of all initial and follow-up
analyses must be submitted simultaneously.
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
the sampling month.
3. Any exceedance of the Groundwater Standards at or beyond the Review Boundary, as specified by the
regulations in 15A NCAC 2L, Groundwater Classifications and Standards, as detected during the
monitoring which will be performed after the initial sampling of Monitoring Wells MW-4 and MW-5, will
mandate the institution of a Corrective Action in accordance with 15A NCAC 2L .0106. Such action may
include the installation of a liner along the interior surfaces of the proposed irrigation pond. If this is
implemented by the Permittee, the interior surfaces of the irrigation pond shall be lined with a synthetic
