Cartwright They had been invited. to attend the special work session to provide input--- towards the Council decision related -to the detection,-of volatile organic hydrocarbon .contamination in the City --water system. as addressed-,-.,in the preliminary study prepared by Bonestroo;- Rosene,. Anderlik & Associates at the Council request- Bob_ Pul'scher of the Springsted Company, the -City's Financial .Consultant, was also present. The engineering- report which had been given to the Council members in advance of the meeting was presented by -Joseph Anderlik and Kelton D. • Barr of Barr Engineering, who had-been-retained by the engineering firm to make the hydrological studies on which the report was based. Mr. Anderlik reiterated what he perceives to be the City 's options for dealing with the detectible levels of contaminants suspected to have originated with the Twin City Ammunition Plant and found in Well #3, . and to a lesser degree in Well #41 since New Brighton has dug their wells deeper into the Mt Simon-Hinckley -aquifer. According to Mr. Barr, it is reasonable to -,conclude the contaminated water would bypass New Brighton and enter the:?,St. Anthony wells=once it is no longer pumped from the corresponding wells in -New Brighton. The alternatives offered by Mr.. Anderlik were ,-for- the City to (_1) - just_ leave the_ wells as they are and. hope the contamination .would not be accelerated once the New Brighton° wells are- fully -in operation; (2) reconstruct Well #3 to 'take .water only from the Jordan aquifer as do Wells #4 and -5 at a cost of $100 , 00'0 , which. would slightly decrease the 'City .water supply and would not guarantee the supply would remain contaminant free, or ( 3) reconstruct Well - #3 so it penetrates into. the Mt. Simon-Hinckley aquifer, at a cost of $300 ;000 , which Mr. Anderlik believes. would guarantee, at least for that well , contaminant free water in the foreseeable future. Mr. Barr gave a slide presentation of maps and drawings to support the recommendation that the third option be pursued since there is no assurance that, in view of traces of contamination detected in We-11 #4 when Well #3 was out .of. operation,, that with the more water systems • which are dug deeper, the faster the contamination of the Jordan aquifer might develop.
