<br />FINDINGS AND RECOMr1EN[)ATIONS <br /> <br />Alternatives developed within ~he la Verkin Springs Unit 1981 Concluding <br />report were reanalyzed along with new alternatives developed during this <br />study. The reanalysis was based on qeoloqic data from 1983 field studies, <br />updated and refinee hydrologic data,' and ~easibilitv grade d@signs prepared <br />during the previous studv. <br /> <br />Salinity reductions at Imperial Da~ were calculated to range, depending on <br />the alternative ane life of pro)ect, from 5.29 to 4.1 mg/l, this resulted <br />in a cost effectiveness for the least expensive alternative (-6) of <br />Sl.9 ffiillion for each mg/l of salinitv reduction at I~perial Dam. Table 1 <br />displays the sun~lary cost for all alternatives. <br /> <br />Findinos indicate the proiert is not presently cost effective and our <br />recom~endation is that studies be discontinued until such ti~e as <br />technological or other factors warrant reconsideration. <br /> <br />BACKGROU','l Arm AUT~nRJTY <br /> <br />During the past ?O vears the la Verkin Springs pro)ect has been studied <br />extensively with several reoorts beine produced including an unpublished <br />feasibility report with appendices. In 1981 a Concluding report was <br />prepared in lieu of finalizing the feasibility report. The Concluding <br />report stated the pro)ect had no cost effective alternative. <br /> <br />Simultaneous with the development and submittal of the Concluding report <br />the Washington County Water Conservancy District (WCWCD) and State of Utah <br />were beine aDrr~ached with a prop~sal fron a private consultant that <br />indicet~d total evaporation with clay lined ponds may ~ake the la Verkin <br />Sprinos pro)ect cost effective. Rased on the private consultants <br />information WCWCD and the State of Utah were successful in having the <br />pro)ect reinitiated bv Congress in 1983. The pro~ect study is presently <br />scheduled to last for 4 years (1983-86) with a total Of S600,000 available. <br /> <br />The WCWCD and State Of Utah offered tn contribute S?30,000 to the study if <br />it could be accelerated from 4 to 3 years.
