<br />Metropolitan Water Supply Investigation Proposal <br />Hydrosphere, Inc. <br /> <br />Septmber 17, 1993 <br />Page 32 <br /> <br />QA for Documents <br /> <br />Quality assurance procedures for written documents have been described above. <br /> <br />QA for Data Set Development <br /> <br />Many of the technical decisions to be made in the MWSI Project will rely on data sets <br />obtained from diverse sources. To insure the integrity of these data a variety of data analysis <br />measures will be used to identify inconsistencies, missing values, and other potential data <br />errors. Techniques such as double-mass balance analysis and line graphing will be used to <br />identify trends, shifts, and outliers in time-series data. Comparisons of data available from <br />multiple sources will be made to verify point estimates. Statistical summaries and descriptions <br />of data sets obtained from study participants will be provided back to those participants for <br />verification. <br /> <br />Hydrosphere has extensive experience in the development and manipulation of large <br />water resources-related data sets. This experience includes development of data sets for <br />litigation suppon and for commercial use. All the applicable quality assurance methods <br />developed in these endeavors will be brought to bear on the MWSI Project. <br /> <br />QA for Computer Model Development <br /> <br />Primarily because of its extensive experience in litigation suppon and commercial <br />software development, Hydrosphere maintains formal software development protocols that will <br />insure the development of accurate and reliable models for the MWSI Project. These protocols <br />call for the preparation of written functional specifications, detailed programming <br />specifications, and a rigorous sequence of unit and system testing. <br /> <br />SCOPE OF SERVICES <br /> <br />Introduction <br /> <br />In January of 1993, the State of Colorado sponsored a convention focused on the issues <br />related to Front Range water supply planning and the interbasin transfer of water. Conference <br />participants recognized that the need for additional water supply for growing Front Range <br />cities, particularly in the Denver metropolitan area, has resulted in numerous controversial <br />trans-basin diversion proposals. Many of these proposals have resulted in extensive <br />controversy and protracted litigation while the necessary agreements and environmental permits <br />continue to be elusive. <br /> <br />Conference panicipants also recognized the importance of improved cooperation between <br />the parties that must be involved in water development and planning decisions. The water <br />supply options that have the best possibilities for success are those that are mutually beneficial <br />to the interests involved. Political problems with new trans-basin diversions and the loss of <br />irrigated agriculture, combined with federal permitting criteria that place great weight on the <br />avoidance and minimization of environmental impacts, necessitate the pursuit of cooperative, <br />low impact solutions. It was funher recognized that some form of state-wide coordination is <br />necessary to adequately address all of the issues involved in the planning and implementation <br />of any major program for acquiring and utilizing water resources along the Front Range urban <br />corridor. Many conference participants felt that the State of Colorado could funher the <br />
