LINCOLN/CHARTER WAY <br /> GROUNDWATER CONTAMINANT PLUME <br /> PAGE 2 <br /> DISCUSSION OF GOALS <br /> • The overall cleanup goal for this plume was discussed. It was generally accepted that the abatement <br /> of the plume to background levels or maximum contaminant levels in a reasonable time period would <br /> be difficult at best, very costly and likely technically unfeasible. For the current time, the attainable <br /> goal of conducting source removal at each location was discussed. A final remedial plan for the <br /> groundwater plume can be determined after the effects of source removal on the groundwater plume <br /> has been evaluated. <br /> • An attempt will be made by Ron Rowe to put all information onto one map for the entire plume. This <br /> will allow the information generated by all the sites to be evaluated more effectively. In addition, the <br /> information presented in this way will enable the group to determine which wells would yield the most <br /> information as a whole and possibly allow for a reduction in number of sampling points in monitoring <br /> the plume overtime. <br /> • The analytical method for methyl tertiary butyl ether(MTBE) and the monitoring frequency for <br /> chlorinated hydrocarbons and other constituents of concern were discussed. It was decided that <br /> MTBE would be detected by EPA method 8020 until such a time that a more precise method be <br /> needed. The number and location of wells in the area needing sampling for chlorinated hydrocarbons <br /> and other constituents of concern will be determined after additional data has been gathered and an <br /> overall plume map is established. <br /> • All efforts will be made to determine the requirements for potential commingling plume funding so that <br /> access to these funds can be made as soon as feasible. <br /> The meeting was a positive, cooperative approach to addressing the considerable groundwater <br /> contaminant plume identified in the area. The next meeting is scheduled for Tuesday, October 29, 1996, <br /> at 10:00 a.m. at the office of PHS-EHD. <br /> If you disagree with this summary or have any questions, please contact Linda Turkatte, Senior REHS at <br /> (209) 468-3441. <br /> Donna Heran, REHS, Director <br /> Environmental Health Division <br /> Linda A.
