The initial thrust included review <br />of 1111 known available data, contact with local water-oriented per&ons, <br />and an on-the-ground appraisal of the area. This preliminary evalua- <br />tion yielded fifteen sprinr;s whose flows could be collected by conven- <br />tional methods for conveyance to a desalination treatment plant. These <br />included ten springs in the Glenwood Springs vicinity, four sprin~5 near <br />Dotsero, and one at South Canyon Creek. Subsequently the amenable springs <br />were estimated at eighteen with four additional springs located in the. <br />Dotsero area, and discounting the &pring on South Canyon Creek. <br /> <br />The flows of these springs have been measured and samples collected <br />monthly beginning in April 1972 except for the month of June when 'most <br />of the springs were inundated by spring runoff of the Colorado River. <br />The total dissolved solids content of the samples has been determined <br />by dry weir;ht analysis in the Grand Junction Projects Office laboratory" <br />Che~ical analyses of the samples have been made in the Regional Office <br />laboratory to provide the planners with data associated with the selec. <br />tion of a suitable desalting process or.processes, copies of these <br />analyses follows.
