ED ENDICH <br /> KEN ENDICH <br /> PAGE 2 <br /> methods for the additional soil borings/monitoring/test wells to PHS/EHD by <br /> May 30, 1995. <br /> The underground storage tank(s) found during this last phase of field work must be <br /> removed in a timely manner. A tank removal plan should be submitted to <br /> PHS/EHD within the next 60 days. <br /> The need for additional assessment with regard to the origin of the groundwater <br /> contaminant plume on this property is unwarranted at this time. Historic groundwater <br /> flow direction data from the Roek site across the street show groundwater flow to be <br /> predominantly to the east, towards that site. The data to date indicates two separate <br /> source areas at each site. The intent of the additional assessment required at this <br /> time is to conclude characterization and initiate source reduction as soon as possible. <br /> The ultimate goal is to achieve site certification and to keep the overall cleanup costs <br /> to a minimum. <br /> The laboratory report in Appendix C was not complete. In addition to the results for <br /> soil borings 63-35', 134-10', 64-20', 134-40', 64-50', 64-60', 135-30' and for the soil <br /> lead analyses, the cover sheet (and any other explanatory documentation) were <br /> missing. Please submit these missing laboratory documents to PHS/EHD. <br /> Also, it appears that the groundwater elevation for monitoring well MW#3 may be in <br /> error. This should be re-evaluated and, if needed, an amendment may be included in <br /> the next quarterly report. <br /> If you have any questions or wish to discuss this letter in more detail, please contact <br /> Linda Turkatte, Senior REHS, at (209) 468-3441. <br /> Donna Heran, REHS, Director <br /> Environmental Health Division <br /> C` <br /> Linda A.
