<br />.. <br /> <br />0/173 <br />Artificial recharge operations will probably have an effect on <br />ground-water quality in some areas. A total dissolved solids map of <br />the ground-water system in the South Platte study area (Hurr, et al, <br />1975, Plate 5) shows a band of total dissolved solids ranging from <br />0-500 mg/l directly beneath proposed recharge sites south of the <br />river. Table E-l shows that the dissolved solids of the recharge <br /> <br />water could be in excess of 1,000 mg/l during the months of recharge. <br />The mixing of this poorer quality water with the good quality ground <br />water will obviously degrade the ground-water~ality, and those <br />depending upon this water for a domest\e's~)y will be adversely <br />/," , ,...) <br />affected. For example, the city- ~T~Brush' ha~ix wells located about <br />#""' ", '".,,; <br />/" . - \;.~ <br />4 miles south of the city \>rf the.west\sJide of Beaver Creek above the <br /><.... ,.)V' , <br />Fort Mor9an Canal, t~~'~ro'l, ~des",tfie only source of water to the city. <br />.

One of these wells has already been contaminated <br />by the poorer quality water leaking from the Fort Morgan Canal and is <br />, going to have to be replaced. It is this kind of problem that will <br />have to be evaluated in considerable detail before a final layout of <br />the recharge plan can be made. In the final analysis there may be a <br />percentage of the proposed acreage that will have to forego the <br />opportunity of receiving a supplemental water supply from recharge <br />because of their proximity to high quality ground-water areas. <br />
