3. Completing a preliminary well interference evaluation for any existing municipal <br />wells, or private wells finished in the same aquifer, that are located within 500-feet of <br />the recommended sites for wells #9 and #10. <br />4. Identifying potential risks of each recommended well site considering aquifer <br />vulnerability, regulatory safe -yield thresholds, and impacts to private wells. <br />5. Preparing a technical memorandum summarizing the findings of the desktop <br />assessment and recommended well sites and test hole/well locations. <br />6. Estimating costs for connecting wells #9 and #10 to the WTP, and for providing <br />on -site pressure filtration for iron and manganese removal, based on all <br />recommended well sites. <br />7. Assisting with preparation of the MnDNR Preliminary Well Construction <br />Assessment. <br />8. Working with City staff to finalize the locations and depths of test holes/wells. <br />For purposes of this proposal, recommended depths and locations for test <br />holes/wells must be based on the aquifers' estimated thickness, extent, and <br />potential to meet future demands, and in consideration of any MnDNR future <br />water appropriation concerns. Assume 72-hour aquifer pumping tests will be <br />completed on test wells. <br />9. Designing and preparing construction specifications for test hole drilling and test <br />well installation, and 72-hour aquifer pumping tests. <br />10. Estimating topographic surveyor and well drilling contractor costs for <br />required test holes/wells and aquifer pumping tests. Assume City will hire the <br />well drilling contractor directly, that four (4) test holes/wells will be required, <br />that each test hole will be finished to a depth of 375-feet, and that each test <br />well will be 6-inches in diameter and installed to a finished depth of 220-feet. <br />11. Providing oversight and geologic logging of test holes and installing and <br />monitoring test wells. For purposes of fee estimating, assume one 10-hour day <br />per test hole and test well. <br />12. Preparing an aquifer pumping test work plan and implementing the 72-hour <br />aquifer pumping tests with assistance from the drilling contractor. Fee estimating <br />should assume two data loggers will be required for each test, and a 10-day <br />monitoring period that includes 72-hour background monitoring, pumping, and <br />recovery periods. Assume staffing will be required for the start of the background <br />period, pumping, and recovery phases of the test. <br />13. Completing the aquifer pumping test data analysis, recommending a PWS well <br />design including structural hydraulics and construction mechanics, and providing <br />Page 5 of 6 <br />
