Six hard copies and one digital copy in MSWord and Adobe Acrobat PDF format will be <br />provided to the State. <br />Tasks 32 and 43: Collection, Analysis and Mapping of Aquifer <br />Property Data <br />0 <br />Objective: <br />The objective of these tasks is to (1) compile existing aquifer property information and create <br />HydroBase-compatible databases with data from the Denver Basin and Lower South Platte <br />Regions, (2) help identify additional data needs in these Regions, (3) support the design of the <br />groundwater field program described in Task 33, and (4) enhance HydroBase with aquifer <br />property data collected during the Phase 1 field activities in Tasks 35 and 36. <br />Approach: <br />Task 32 Collect Historic Aquifer Property Data <br />• Obtain existing electronic databases that are currently maintained by the State and, if <br />available, the USGS and the available paper-copy reports (as identified in Appendix B7 of <br />the SPDSS Feasibility Study) that contain information on (a) hydraulic conductivity, (b) <br />transmissivity and (c) specific yield and storage coefficient. <br />Task 43.1 Analyze and Map Historic Aquifer Property Data <br />Coordinate with the Relational and Spatial System Integration Consultant to determine the <br />database structure that will be used for entry and/or formatting of these historic data. <br />Reformat the existing electronic databases into the appropriate DSS (HydroBase) formats <br />Evaluate whether the non-electronic historic data is suitable for addition to the SPDSS <br />database. These data will be evaluated to determine if it may provide an enhanced <br />understanding of the Denver Basin and Lower South Platte Regions' ground water <br />systems. Data that are necessary for future use to configure, calibrate and use in the <br />groundwater models that are a part of the SPDSS will be converted to an electronic format <br />and added to HydroBase. <br />• Summarize the database for descriptive purposes, including the database fields, number of <br />entries in each field by aquifer, and sources of data. <br />• Prepare digital contour or point plot maps of (a) hydraulic conductivity, (b) transmissivity, <br />and specific yield and storage coefficient for each aquifer, including the location of data <br />used in the contouring. Contour maps will be prepared for those data elements with <br />sufficient data to reliably develop contours, while sparse or highly variable data will be <br />presented on point plot maps. <br />For the Denver Basin Region the mapped aquifers include the following, as defined in the <br />SPDSS Feasibility Study: <br />- Alluvium of the South Platte and its tributaries <br />-Upper Dawson <br />SPDSS Groundwater SOW, Phase 1 Page 5 <br />
