• In cases where an observation well is not coupled with an existing high capacity well, a single <br />borehole aquifer performance test will be conducted. Water from the single-well testing will <br />be discharged to overland flow without treatment. <br />• As determined in Phase l, no discharge permits will be sought for water produced during the <br />aquifer testing since no water will be discharged to surface water bodies. <br />• In both the singie-well and multi-well tests, water level data will be recorded during the <br />pumping and recovery phases using a pressure transducer and data logger. Aquifer testing <br />results will be reduced and interpreted using indushy standard analysis techniques after <br />adjusting for regional effects. <br />• An in-well pressure transducer and data logger will be installed in each of the 25 sites and <br />operated for at least 6 months and up to a 12-month period to characterize seasonal effects on <br />water levels. The data will be recorded at an hourly interval and normalized to elevation for <br />reporting. After initial installation and confirmation of operation over a two-week start-up <br />period, data will be retrieved on a quarterly to semi-annual basis. <br />• Following aquifer testing, the in-well pressure transducer and data logger from the test <br />location may be moved from the observation well in which it was originally installed, to <br />another existing monitoring well (such as one operated by a cooperating entity or by the State) <br />located in an area that has been determined a higher priority for continuous water level <br />monitoring. This is intended to allow optimal use of the in-well pressure transducer and data <br />logger and avoid wateX-level data bias resulting from monitoring the localized drawdown of <br />the originally paired irrigation well, after aquifer testing is completed. <br />� The data collected during the installation and testing of the observation wells will be analyzed <br />under Tasks 42, 43 and 44 for aquifer configuration, aquifer properties and aquifer water <br />levels, respectively. <br />Deliverables: <br />Task 35.2 Phase 2 Denver Basin Region Alluvial Well Construction and Testing <br />Technical Memorandum <br />A single Technical Memorandum will be prepared for the alluvial wells constructed in the <br />Denver Basin Region during Phase 2 of up to 10 pages in length (with additional pages for <br />figures, tables and appendices, as needed). This Technical Memorandum will focus on <br />information collected during Phase 2 and will be an update to the Task 35.2 Phase 1 Technical <br />Memorandum. <br />� This memorandum will include the following: <br />- an executive summary of the Denver Basin Alluvial Well Construction and testing <br />- a description of the chronology of well construction <br />- summary of Denver Basin alluvial well drilling <br />SPDSS Groundwater SOW, Phase 2 6 <br />
