The revised version of the work plan includes changes requested by you and <br />J oIm Betcher in a melTIorandum dated March 2, 2006 and the telephone conversation I had with Mr. <br />Betcher on March 7, 2006. Major revisions to the work plan include: <br /> <br />. Collecting additional soil samples in the source area at multiple depths to assess vertical <br />concentration gradients ofVOCs in the unsaturated zone; and <br /> <br />. Hydroprofiling at five locations to characterize geologic conditions and prelilninarily <br />dOCUlnent VOC concentrations in groundwater at various depths. This infOlTI1ation will be <br />used to design monitoring wells for the site. <br /> <br />Please contact us at your convenience if you have questions regarding our approach to con1plete the <br />investigation. We look forward to hearing from you. <br /> <br />Sincerely, <br /> <br />GOLDER ASSOCIATES INC. <br /> <br /> <br />c~r <br /> <br />Minnesota Office Manager and Associate <br /> <br />Patrick Dunlavy <br />Senior Consultant <br /> <br />,enclosures: Second Supplemental Phase II Work Plan <br />cc w/enclosures: John Maas/Mounds View School District <br />Dan Colton/Leonard, Street & Deinard <br /> <br /> <br />OFFICES ACROSS AFRICA.
