Monitor wells MW-1, MW-2 and MW-3 shall be sampled every March, July, and November for the parameters listed below. 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) off all monitoring wells shall be surveyed relative to a common datum. Water Level Chloride Fecal Coliforms Nitrate -Nitrogen (NO3-N) pH Total Dissolved Solids (TDS) Total Organic Carbon (TOC) Ammonia Nitrogen (NH3-N) Volatile Organic Compounds - In November only using one of the following: (A) Standard Method 6230D, PQL at 0.5 ug/L or less (B) Standard Method 6210D, 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 4 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 must provided a PQL at 0.5 ug/L or less 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. If any volatile organic compounds are detected by the methods listed, then the Wilmington Regional Office Groundwater Supervisor, telephone number (910) 796-7215, 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. 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/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. The results of the sampling and analysis must be received on Form GW-59 (Groundwater Quality Monitoring: Compliance Report Form) by the Division of Water Quality Information Processing Unit 1617 Mail Service Center Raleigh, North Carolina 27699-1617on or before the last working day of the month following the sampling month.
