<br />"' <br /> <br />. .",. <br /> <br />. <br /> <br />. <br /> <br />2. Review the well logs listed in the Beck Report and obtain and review well logs from <br />selected water wells drilled in the area and other sources such as oil field logs to determine <br />the relative depths of the four primary aquifers underlying the District. A review of the <br />depths of the screened perforation intervals to confirm their source will also be undertaken. <br /> <br />Product: a. <br />b. <br /> <br />The maps in the original Beck report will be revised and updated. <br />A hard copy and electronic copy of wells and their perforated intervals <br />and interpreted sources will be developed. <br /> <br />3, Evaluate the locations of wells in the existing monitor well network to insure representative <br />water levels in the aquifers are being measured. <br /> <br />Product: <br /> <br />Recommended alternative network of wells identified in hard copy and <br />electronic format will be developed. <br /> <br />4. Obtain and utilize LANDSAT imagery to identify irrigated lands within the district and <br />associated locations of wells from Task I with area water level changes. <br /> <br />Product: <br /> <br />An overlay of the LANDSAT imagery for a selected period in 1999 will <br />be overlain on the well location map and water level change map(s). <br /> <br />5. Confirm water use in the District by actual measurement or approximation to enable the <br />impact of historic pumpage to be quantified for future projection of declines. Sources of <br />information may include electrical power records, and natural gas consumption records, <br />and calculated water demand using the Blaney-Criddle method with climatological input <br />data from local sites. <br /> <br />Product: <br /> <br />A summary of water use estimates relating use to areas will be developed, <br /> <br />6. .Create digital maps to show the relative locations of the four main aquifers as "layer" and <br />show the water level change(s) in each of the aquifers. Information from both Kansas and <br />Oklahoma may be included, <br /> <br />7, Review and analyze available information relating to the status of abandoned wells to <br />determine the potential for improperly abandoned wells in the District. Sources for tills <br />information may include the county assessors office, the State Engineers Office and the <br />Water Quality Control Division of the Colorado Department of Health. <br /> <br />8. Data obtained from all sources may be verified with District representatives to confirm <br />its accuracy and relevance. <br /> <br />9. MWE will use the District's Global Positioning Satellite data for verifying well locations <br />as necessary. <br /> <br />3 <br /> <br />P:\1999\99.028\OOlOO\wp\Pan I Scope of Servicea.wpd <br />
