• The Consultant's on-site representative will be present for at least 75 percent of all drilling <br />activities. The on-site representative will maintain a log of all significant well construction <br />and testing activities that occur in their presence. Cores will be photographed for additional <br />documentation and stored in waterproof cardboard core boxes. Individual samples collected <br />for laboratory testing will be preserved in a manner consistent with the planned testing. <br />• Laboratory testing of vertical permeability will be conducted on 2 samples of representative <br />lithologies from the upper core run. One moisture retention curve and 2 horizontal <br />permeability tests will be conducted on samples from each of the cores collected in the <br />uppermost aquifer and from the target completion depths. The objective of the vertical <br />permeability assessment in the upper bedrock interval is to assist in determination of vertical <br />leakance characteristics. The horizontal permeability and moisture retention curves are to <br />assist in determination of hydraulic properties of the bedrock aquifers. <br />• Drilling mud and cuttings will be disposed of off-site. The site will be graded and a dryland <br />seed mix spread, if required. <br />• The well will be completed with up to 5-inch diameter Schedule 80 PVC casing and a screen <br />length of no more than 200 feet Well completion will be in accordance with State regulations. <br />The well screen of the observation well will be installed to a depth corresponding to the <br />producing aquifer of the high-capacity bedrock well. <br />• The well will be developed by surging and pumping and the produced water discharged to the <br />surface in accordance with state regulations. <br />• A surveyor licensed in the State of Colorado will be selected and sub-contracted by the <br />Consultant to provide vertical and horizontal coordinates using precision differential GPS <br />methods that provide vertical accuracy within 0.1 feet and horizontal accuracy within 2.0 feet. <br />• A multi-well aquifer pumping test will be conducted after the well is completed and <br />developed. A nearby large-capacity well will be used as the pumping well, with the well <br />constructed by the Consultant used as the observation well. As included in Exhibit D, Task <br />Compensation, pumping from the high-capacity well will be conducted at a constant rate for a <br />period between 8 and 72 hours based on an anticipated test duration of 36 hours. Water level <br />data will be recorded during the pumping and recovery phases using a pressure transducer and <br />data logger. Aquifer testing results will be reduced and interpreted using industry standard <br />analysis techniques that include appropriate adjustments for regional water level changes, and <br />other factors. <br />• An in-well pressure transducer and data logger will be installed in each observation well 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 />SPDSS Groundwater SOW, Phase 2 10 <br />
