Due to the proximity of the utility conflicts (and the high risk of damaging them and compromising the health and <br />safety of the field personnel), a mushroom cap of three feet deep and 1 foot wider than the original well <br />borehole diameter will not be constructed. <br />Grout calculations <br />The estimated cement (95%)/bentonite (5%) grout volume for over-drilled wells MW-1, MW-3, and MW-7 is 56 <br />gallons each. The estimated cement (95%)/bentonite (5%) grout volume for over-drilled wells MW-5 and MW-6B <br />is 127 gallons and 135 gallons, respectively. <br />The estimated cement (95%)/bentonite (5%) grout volume or neat cement volume for blast perforated wells MW- <br />2 and MW-4 is 37 gallons each. The estimated cement (95%)/bentonite (5%) grout volume or neat cement <br />volume for blast perforated well MW-6A is 36 gallons.
