Revision 0 (December2005). We received the report on December 28, 2005.Overall the report looks good. None of the samples apprh!ched.ee§iWpapprh!chcd..ee§iWp levels. I have a couplespecific comments on the documents:J ."'.' .. ' ••.... ,-.;-,1. Section 4.1: Please note if a temporary benchmark was used to complete the level loop andif it was the same mark used in previous brroundwatergroundwater surveys. Even though the wells mayhave frost jacked the survey readings taken at this event should be able to stand alone toproduce groundwater elevations. Please produce a contour map with the calculatedgroundwater flow direction.2. Appendix D, Table 2: I don't think the RPD is 0% for those compounds with nondetect inone sample and small detections in the other. Since zero can't be averaged the RPDwouldn't be calculated.3. Please explain in the introduction or conclusion& that this remedial action is the result of adetermination made during the proposed plan/ROD and that this is' the first of (three orfour?) seasonal sampling events.If you have any questions, please cal! me at (907) 269-3053.~~~C:~::~iccm~El.,ilOmnen:£!1.1:'Sincerely,Je1T BrownieEn\iironmenta't-sPe~ialistcc:Mr. Steven A.
