sampled every March, July, and November for the following parameters:
NO3
Ammonia Nitrogen
TDS
TOC
pH
Water Level
Chloride
Bromide
Barium
Volatile Organic Compounds - In November only by Method 6230D below
Method 6230D (Capillary - Column), "Standard Methods For The Examination of
Water and Wastewater", 17th ed., 1989
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 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/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.
If any volatile organic compounds are detected by Method 6230D, then the Washington
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, P.O. Box 29578 Raleigh, N.C. 27626-0578 on or before the last
working day of the month following the sampling month.

original copies of a scaled topographic map (scale no greater than 1":100') signed and
sealed by a professional engineer or a state licensed land surveyor that indicates all of the
following information:
a. the location and identity of each monitoring well,
b. the location of the waste disposal system,
c. the location of all property boundaries,
d. the latitude and longitude of the established horizontal control monument,
e. the relative elevation of the top of the well casing (which shall be known as the
"measuring point"), and
f. the depth of water below the measuring point at the time the measuring point is
established.
The survey shall be conducted using approved practices outlined in North Carolina General
Statutes Chapter 89C and the North Carolina Administrative Code Title 21, Chapter 56.

disposal system and determine the latitude and longitude of this horizontal control
monument to a horizontal positional accuracy of +1- 10 feet. All other features listed in a.
through e. above shall be surveyed relative to this horizontal control monument. The
positional accuracy of features listed in a. through e. above shall have a ratio of precision
not to exceed an error of closure of 1 foot per 10,000 feet of perimeter of the survey. Any
features located by the radial method will be located from a minimum of two points.
Horizontal control monument shall be installed in such a manner and made of such
materials that the monument will not be destroyed due to activities that may take place on
the property. The map shall also be surveyed using the North American Datum of 1983
coordinate system and shall indicate the datum on the map. All bearings or azimuths shall
be based on either the true or NAD 83 grid meridian. If a Global Positioning System
(GPS) is used to determine the latitude and longitude of the horizontal control monument, a
GPS receiver that has the capability to perform differential GPS shall be used and all data
collected by the GPS receiver will be differentially corrected.
The maps and any supporting documentation shall be sent to the Groundwater Section,
