<br />F. REPORTS: <br /> <br />'. <br /> <br />fe <br /> <br />to investigate highway bridge footings are held by the Colorado Highway <br />Department; data for soil borings to investigate building foundation <br />conditions are held by the Colorado Geological Survey, and by most <br />county and city building departments. <br /> <br />Masses of data held in computerized data ba~es such as those of the U.S. <br />Geological Survey and the State Engineer's office will facilitate computer <br />sorting, proce3sing, and interpretation. Other large blocks of data are held <br />in paper copy from or microfilm form and will require more personnel- <br />intensive searching, sorting, and compilation of the data prior to mapping. <br />Data to be compiled for entry into the project data base include site <br />location information, land surface alti1ude, and depths to bedrock and <br />ground water. Hydrologic conductivity and transmissivi1y data will be <br />included in the data base when such data are available from original <br />sources. <br /> <br />Work maps will be prepared at a map scale of I :24,000 (I mile equals <br />about 2-1/2 inches). Once the work maps have been completed and <br />checked, thc maps will be digitized and incorporated into a GIS. Final <br />maps will be at a scale of 1:50,000 (I mile equals about 1-1/4 inches) for <br />publication. <br /> <br />The results of the shallow aquifer study will be published as a series of map <br />reports because of the size of the study area and the scale of the maps. A <br />set of six maps will form tile basis of each report. The maps will show: <br /> <br />I. The altitude of the bedrock surface underlying the unconsolidated <br />sediments of the study area; <br /> <br />2. The thickness of the unconsolidated sediments; <br /> <br />3. The altitude of the water table and direction of ground-water movement <br />in the shallow aquifers; <br /> <br />4. The depth to the water-table; <br /> <br />5. The saturated thickness of the shallow aquifers; <br /> <br />6. The ground-water quality. <br /> <br />The maps will be published as part of the U.S. Geological Survey <br />Hydrologic Investigation Atlas or similar series of reports. The maps also <br />will be digitized and made available in electronic form upon request as a <br /> <br />4 <br />
