i W~Q~~ <br />of the flooded workings and subsided roof <br />zone. <br />Installation of the wellpoints will serve <br />two objectives. First, monthly monitoring of <br />the water levels in the wellpoints will allow <br />for identification of water storage in the <br />unconsolidated deposits underlying each <br />drainage; and second, if water is present, it <br />will be sampled quarterly and submitted for <br />analysis of those constituents listed in Tables <br />2A and 2B. The successive sampling results <br />will be compared as well as the upgradient <br />and downgradient analytical results to <br />evaluate the general quality of water <br />contained in the unconsolidated deposits <br />underlying the two drainages. CDMG will <br />be consulted to obtain a final determination <br />of status of the sites. <br />HYDROLOGY BASELINE <br />MONITORING <br />Data Review <br />Review of existing hydrologic literature <br />for the State of Colorado, and the proposed <br />site, will be conducted to provide a regional <br />hydrogeologic baseline database. <br />Data Management <br />To provide the necessary data analysis for <br />permit submittal, a unified data management <br />system will be established using a com- <br />mercially available database management/ <br />GIS system. Any statistical evaluations will <br />be performed using stratagraphirs software to <br />provide continuity with CDMG analysis <br />methodologies. <br />A coherent data set will allow useful, <br />coordinated data manipulation analysis and <br />display and reduce the amount of effort <br />needed to perform these operations as new <br />data is added to the database. <br />HYDROLOGIC BASELINE <br />Objective <br />The primary objectives of the hydrologic <br />baseline study are, to the extent possible, <br />describe the components and interaction of <br />surface and ground water systems within the <br />project area, assess project water demands, <br />determine water supply availability, and <br />determine the status of alluvial valley floors <br />in the Project area. This information will <br />provide the basis for determining the extent <br />of potential impacts associated with altering <br />hydrologic characteristics due to future <br />mining. By determining the nature of the <br />characteristics affected, possible mitigative <br />measures may be implemented. Because of <br />the nature of mining activities it is <br />recognized that not all impacts may be <br />mitigated. Therefore, a thorough and <br />competent analysis of baseline conditions will <br />be undertake^ in order to provide a means <br />for predicting the nature, areal extent and <br />temporal aspects of unavoidable impacts. <br />Approach <br />A baseline data report will be generated <br />by initiating a literature search, implementing <br />a baseline monitoring program, conducting <br />field activities and performing preliminary <br />data analysis. The results of the monitoring <br />program will be compared with existing <br />regional and site specific water resources <br />7 <br />
