GROUNDWATER REQUIREMENTS
1. Prior to beginning waste disposal operations, three (3) monitor wells, one (1) upgradient
and two (2) downgradient, shall be installed to monitor groundwater quality. The well(s)
shall be constructed in the bedrock aquifer and such that the water level in the well is never
above or below the screened (open) portion of the well at any time during the year. The
general location and name for each well is marked on Attachment A. Each monitoring well
shall be located at the review boundary, constructed in accordance with this permit, and
approved by the Mooresville Regional Office.
2. Monitor wells MW-1, MW-2 and MW-3 shall be sampled initially after construction (and
prior to waste disposal operations) and thereafter every January, April, July, and October
for the following parameters. -
Total Coliform NO3
Ammonia Nitrogen TDS
pH TOC
Chloride Specific Conductivity
Water Level
Volatile Organic Compounds - In October only (by Method 1 or 2 below)
Method 1: Method 6230D (Capillary - Column), "Standard Methods For The
Examination of Water and Wastewater", 17th ed., 1989
Method 2: Method 502.2 "Methods For The Determination Of Organic Compounds
In Drinking Water", U.S. EPA-600/4-88/039
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.
4

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.
If any volatile organic compounds are detected by method 6230D, or the equivalent method
502.2, then EPA methods 604 and 611 must also be run to detect other organic compounds
which may be present. The results of all analyses specified in the monitoring requirements,
�
including 604 and 611 if required, must be submitted simultaneously.
The results of the sampling and analysis shall be sent to the Groundwater Section, Permits
and Compliance Unit, P.Q. Box 29535 Raleigh, N.C. 27626-0535 on Form GW-59
