Meyer, Director Mr. James Brown Solid Waste Director Madison County Landfill 101 Brigman Farm Road Marshall, N.C. 28753 RE: Groundwater Monitoring Results - Madison County Landfill (Permit No. 58-03) Dear Mr. Brown, The monitoring report for the October 2, 1996 sampling event at the Madison County Landfill indicates that a statistical increase of metals concentrations over background may exist in several wells at the site. Although the results may be biased by a number of factors (ie. suspended solids in the sample prior to acidification, inadequate statistical sample, etc.), the issue of possible contamination must be addressed or the landfill risks beginning required assessment monitoring (Rule .1634). As part of your next scheduled sampling requirement, please have filtered and unfiltered samples analyzed for metals. This should give some indication if suspended solids in the samples, the most likely cause of misleading results, contribute to the increase in detected concentrations. Thank you for your cooperation. If you have any questions, please call me at (919) 733-0692, ext. 257.

N.C. 28753 �sa16 17 ? j�00 Q ` JUL RECEIVED SWS-WSRO EHNR RE: Water Quality Monitoring - Madison County Landfill (Permit 4 58-03) Dear Mr. Brown: The Solid Waste Section has reviewed the April 24, 1997 monitoring well data from the lined landfill. The data is part of the monitoring report submitted by The Fletcher Group on behalf of Madison County. For the last two sampling events methylene chloride was found in the sample from MW-3. The concentrations detected (14 ppb and 5.lppb) are technically in violation of the 2L groundwater standard of 5 ppb for methylene chloride. The landfill must now demonstrate that the data for methylene chloride is incorrect or proceed with assessment monitoring within 90 days of the last sampling episode (Solid Waste Management Rule .1634). If the decision is to demonstrate that the data is flawed, please notify me immediately and provide a schedule for completing this demonstration. The demonstration may include, but is not limited to any of the following: resampling of MW-3, proving laboratory contamination of the samples or sampling error, or furnishing some other evidence that the contaminant is coming from a source other than the landfill. Is there surface water infiltration because of a problem with the integrity of the well? Has there been a spill of anything on the ground near the well? The initial impression upon seeing methylene chloride in low concentrations in the data was that it was probably a lab contaminant. Methylene chloride is a common laboratory solvent and in cases where lab contamination of a sample has occurred it is often the compound found. However, with the situation here it has been identified only in MW-3 and during two consecutive sampling events. If it is a lab contaminant it's very coincidental. However, the fact that only one compound was found in low concentrations tends to indicate that the landfill is not the source. Usually groundwater affected by a landfill has several identifiable compounds. More supporting evidence is that methylene chloride was not found in the leachate sample. Nevertheless, a demonstration must be made for a source other than the landfill or the County should proceed with assessment monitoring. P.O. Box 27687, P4.
