N. GROUNDWATER REQUMEMENTS
1. Monitor wells MW-1, MW-2, MW-3, MW-4, MW-5 and MW-6, shall be sampled every
January, April and September for the following parameters:
NO3-N NH3-N
TDS TOC
PH Water Level
Chloride Chemical Oxygen Demand
Fecal Coliforms
Volatile Organic Compounds - In September only (by Method 1 or 2 below)
4

Volatile Organic Compounds (VOC) by one of the following methods:
(A) Standard Method 623OD, PQL at 0.5 ug/L or less
(B) Standard Method 621 OD, PQL at 0.5 ug/L or less
(C) EPA Method 8021, Low Concentration, PQL at 0.5 ug/L or less
(D) EPA Method 8260, Low Concentration, PQL at 0.5 ug/L or less
(E) Another method with prior approval by the Groundwater Section Chief
Any method used must meet the following qualifications:
(1) A laboratory must be DWQ certified to run any method used_
(2) The method used must, at a minimum, include all the constituents listed in Table VIII of
Standard Method 6230D.
(3) The method used trust provided a PQL at 0.5 ug/L or Iess which 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 at 0.5 ug/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/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 analyses specified in the monitoring requirements,
including 604 and 611 if required, 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.
2. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall be
provided.
The COMPLIANCE BOUNDARY for the disposal system is specified by regulations in 15A
NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary is for the
disposal system constructed after December 31, I983 is established at either (1) 250 feet from
the waste disposal area, or (2) 50 feet within the property boundary, whichever is closest 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).

In accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established around the
disposal systems midway between the Compliance Boundary and the perimeter of the waste
disposal area. Any exceedance of standards at the Review Boundary shall require remediation
action on the part of the Permittee.

proper operation of the subject facilities.
The Permittee or his designee shall inspect the wastewater treatment and disposal facilities to
