<br />. <br /> <br />uncertainty in the future values of the planning variables and the <br /> <br /> <br />future is likely to include a combination of some or all of these <br /> <br /> <br />alternative futures. Therefore, future values of the planning <br /> <br /> <br />variables including population and employment cannot be predicted <br /> <br /> <br />with certainty for small areas appropriate for this study. Each <br /> <br /> <br />individual problem solving exercise within the study must include <br /> <br /> <br />a complete analysis of the uncertainties unique to the problem and <br /> <br /> <br />the alternative solutions to that particular problem including <br /> <br /> <br />a test of the sensitivity of the problem and each alternative solu- <br /> <br /> <br />tion to changes in the planning variables. <br /> <br />Water Quality <br /> <br />PROBLEMS AND NEEDS <br /> <br />Water quality in the South Platte River basin is as varied <br /> <br /> <br />as the topography. A few streams in the mountainous areas are in <br /> <br /> <br />a pristine state while others are biologically dead from past <br /> <br /> <br />mining operations. Other streams are affected by sediment carried <br /> <br /> <br />in runoff from new housing developments and from inadequate treat- <br /> <br /> <br />ment of wastewater. Streams along the Rocky Mountain Front Range <br /> <br /> <br />receive sewage from Colorado's largest cities which, in many cases, <br /> <br />do not provide adequate treatment. The problem is compounded by <br /> <br /> <br />the low flows encountered in these streams as compared to the volume <br /> <br /> <br />of wastewater generated. This means that much of the wastewater <br /> <br /> <br />must receive advanced treatment in order to meet water quality <br /> <br />. <br /> <br />13 <br />
