From: Lam, Shelly [mailto:lam.shelly@epa.gov] Sent: Tuesday, September 23, 2014 11:32 AMTo: Muniz, Nuria; JAWORSKI, MARK; Miller, ChristinaCc: Lam, ShellySubject: West Vermont Cross-Sections Attached are cross-sections Weston prepared for West Vermont. I can’t remember if I sentyou these before. Weston overlaid resistivity profiles on the geologic cross-sections. One of the PRPs conductedresistivity in lieu of logging lithology. You can clearly see that the intermediate till (665-678feet), which one of the PRPs claims is a “confining layer,” is not present everywhere and isoften thin where present. In particular, this unit is missing near Michigan Plaza’s Source Area C,show on on 5-5’. It is missing entirely in well MMW-14D. Shelly Lam, LPGActing Section ChiefResponse Section 2U.S. EPA2525 N.
