IV. GROUND3YATER REQUIREMENTS
1. The four (4) existing monitor wells shall be sampled every March, July and November for
the following parameters:
NO3 Ammonia Nitrogen
TOC PH
Chloride Water Level
Total Suspended Solids Total Dissolved Solids
Copper Orthophosphate
COD Nickel
Lead Chromium
Iron S 04
Volatile Organic Compounds - In November only (by Method 1 or Method 2 below)
Method 1: Method 6230D (Capillary - Column), "Standard Methods for the
Examination of Water and Wastewater", 17th edition, 1989
4

Method 2: Method 502.2 "Methods for the Determination of Organic Compounds in
Drinking Water", United States Environmental Protection Agency - 600/4-
88/039
The measurement of water level must be made prior to sampling for the remaining
parameters. The depth of 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 relative elevations of the measuring point for each monitoring well.
If TOC concentrations greater than 10 rng/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, 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 analysis 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 N.C. Division of
Environmental Management, Post Office Box 29535 Raleigh, N.C. 27626-0535, on Form
GW-59 (Compliance Monitoring Report Form) every April, August and December.
2. The COMPLIANCE „BOUNDARY for the disposal system is specified by regulations in
15A NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary is
established at either (1) 250 feet from the spray irrigation field, or (2) 50 feet within the
property boundary, whichever is closet to the waste disposal area. An exceedance of
Groundwater Quality Standards at or beyond the Compliance Boundary is subject to
immediate remediation action in addition to the penalty provisions applicable under General
Statute 143-215.6A (a) (1).
For facilities permitted on or after December 30, 1983, the Compliance Boundary is
established at the lesser of 250 feet from the spray irrigation field, or 50 feet within the
property boundary.
The REVIEW BOUNDARY for the disposal system is specified by regulations in 15A
NCAC 2L, Groundwater Classifications and Standards. A REVIEW BOUNDARY is
established around the disposal systems midway between the Compliance Boundary and
the perimeter of the waste disposal area. When the concentrations of any substance equals
or exceeds the maximum allowable concentrations of that substance at the REVIEW
BOUNDARY , as determined by monitoring, the permittee shall either (i) deomonstrate,
through predictive calculations or modeling, that natural site conditions, facility design and
operational controls will prevent a violation of standards at the Compliance Boundary; or ,
(ii) submit a plan for the alteration of existing site conditions, facility design or operational
controls that will prevent a violation of standards at the Compliance Boundary, and
implement that plan upon its approval by the Director.
3. Any additional groundwater quality monitoring, as deemed necessary by the Division of
Environmental Management, shall be provided.
