This is very good. <br /> I did not upload the plan to Geotracker. I decided to wait for your <br /> comments. <br /> I will correct/edit the work plan per your instructions and upload it <br /> onto Geotracker .. <br /> Have a good weekend. <br /> Sincerely, <br /> Javad <br /> On Apr 4, 2014, at 12:01 PM, "Vicki McCartney [EH]" <br /> <vmccartneyna,sicehd.com> wrote: <br /> Good morning Javad, <br /> I have reviewed the well destruction work plan and have <br /> given the work plan to Nuel Henderson today to review and <br /> comment. <br /> I did not find the work plan in GeoTacker. If you have not <br /> already uploaded the work plan, please make the following <br /> corrections to the work plan prior to uploading it. <br /> Table 1, you indicate that there was no contamination in <br /> soil and groundwater collected from MW-3R. This is not <br /> correct. Contamination was found in both soil and <br /> groundwater from MW-3R and this well must be drilled out, <br /> not pressure grouted. (Also, DPE10 (s) did not have <br /> contamination in the soil samples.) <br /> Figure 1 is not included in the work plan, but Figure 3 is <br /> and it is difficult to read this well location map. <br /> Figure 2 illustrates that cementtbentonite slurry will be used <br /> but the narrative states that neat cement will be used to <br /> grout the annular seal. Please use neat cement and <br /> correct Figure 2. <br /> You did not mention using a tremie pipe, nor did you <br /> mention what pressure will be applied, nor the length of <br /> time the pressure will be applied when pressure grouting. <br /> have reviewed previous reports and was able to find <br /> documentation for all wells except MW-10 and MW_ <br /> 11 stating that eight-inch augers were used when installing <br /> The wells.
