"-v N' ,r.
The measuring points (top of well casing) of all, monitoring wells shall be
surveyed relative to mean sea level (M.S.L.). The depth of the water in each well
shall be measured from the surveyed point on the top of the casing. The water level
elevations shall then be determined relative to (M.S.L.).
The numbers in parentheses represent the maximum allowable concentrations in
groundwater for the various analytical parameters, as specified in 15 NCAC 2L
[Groundwater Classifications and Standards]_ Unless otherwise noted, the
concentrations are given in parts per million.
If TOC concentrat_ons 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/l, this concentration will
be taken to represent the naturally occurring TOC conccntration. 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 numbers in parentheses represent the maximum allowable concentrations in
groundwater for tYe various analytical parameters, as specified in 15 NCAC 2L
[Groundwater Classifications and Standards]. Unless otherwise noted, the
concentrations are given in parts per million.
The results of the sampling and analysis shall be sent to the N.C. Division of
Environmental Management 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 15
NCAC 2L, Classifications and Water Quality Standards applicable to the
