The report was submitted for replacement of <br /> Well MW-3, which is believed to have been constructed improperly allowing grout to eniel•6e well. <br /> The installation of�aoandwatcr monitoring wells at the facility was required by the 26 August 2004 <br /> Calafo:iia Water Code Section 13267 Order. <br /> I have the following comments on the workplan: <br /> I The workpian:docs not adequately describe the construction of Well MW-3 to deterrnine ifit is a <br /> candidate for pressue grouting, Please submit a well construction detail for Well MW-3- <br /> 2 <br /> 2 Please deseritle what techniques will be used to remove sediment from Well MW-3 prior 1.0 filling it <br /> with grout. <br /> 3 Use of "neat bentonite"as well grout is not acceptable. Please use neat cement or a r,.cat <br /> vement/bentotite slurry with no more than five percent of bentonite by weight. <br /> 4 It is unclear if Well MW-3-has been surveyed. Please provide the survey location data. If the well <br /> has not been surveyed,describe.how that will be accomplished. <br /> 5 The attached figure does not present groundwater elevations or elevation contoars as stilted in the <br /> workplan so evaluation of the proposed location of Well MW-5 is not possible. <br /> By 16 -lamb 2005, please submit a revised workplan that addresses the items listed abc,.ii <br /> any questions please telephone me at(916)464-4616. <br /> =may ,V <br /> 000 t <br /> iTsZC %D <br /> 'O <br /> TIMOT-HY R. 0133MEN -«o <br /> Waste}discharge to land Unit Zr-i <br /> -4 --C _ <br /> cc; MargaretLagorio; San Joaquin County Environmental Health Department, Stockton <br /> .7effory J.5char"f,Esq., Sacramento <br /> David Wgich,Neal O.
