If TOC concentrations &eater than 10 mg/l are detected in any down gradient 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 down gradient wells shall be subject to the additional sampling and analysis as described above. If any volatile organic compounds are detected by the methods listed then the Washington Regional Office Groundwater Supervisor, telephone number (252) 946-6481, 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, Perrnits and Compliance Unit, 1636 Mail Service Center, Raleigh, N.C. 27699-1636 on or before the last working day of the month following the sampling month. 3.
