Top of well pads about 6 inches above land surface. <br />? /MW -5 through MW -7 installation date Is date the well, filter pack and grout placement were Installed in the borehole, but completion with concrete pad, bollards <br />and protective steel riser was conducted at a later date. <br />3 /Well total depths for MW -1 through MW -4 measured by Golder 7/30/2010 from the top of the PVC well casing top; bls = below land surface. Borehole and well <br />construction logs were unavailable for MW-4. Information provided for MW -4 was obtained from a video survey of the well performed on July 30, 2010 MW -1 <br />well casing likely extended sometime after construction based on differences in drilled depth based from borehole log and total depth measurement made <br />7/30/2010; was reduced by 0.30 feet on 01/10/2013 to enable closing and securing the steel protective riser lid. <br />!I/ Screened interval Is the depth interval of the nominal length of the screen pipe section, and not the actual measured length of the perforations provided on the <br />well construction diagrams in Appendix D. <br />1 \10 \81640ak 0400\ gwcharwellinstallfieldrep_ 09augl3 \reporttables_revO8O62013 docx <br />• <br />it Golder <br />Associates <br />
