Well <br />development will be conducted by airlifting from above the screen and surging within the screened zone <br />using a double surge block. <br />The supervising hydrogeologist or geologist will monitor the discharge water during well development. <br />Wells will be developed until field parameters (temperature, pH, and conductivity) are stable and the <br />discharge water is clear and free of sediment. <br />Detailed geologic logs and construction diagrams will be prepared for each new well. The logs will include <br />information on geologic conditions, boring depth, drilling conditions, depth to groundwater, and well <br />construction (depth, screened interval, screen slot size, filter pack type and interval, well seal type and <br />interval, and other pertinent information). All required forms will be submitted to the DWR including <br />Form 51 Notice of Intent to Construct Monitoring Hole(s) and Form 46 Monitoring /Observation Water <br />Well Permit Application with the applicable filing fee per well. <br />10.1.3 Groundwater Monitoring Frequency <br />Groundwater monitoring will be conducted quarterly for five quarters to provide a sufficient data for <br />statistical analysis of baseline conditions. Following the initial five quarters, groundwater will be <br />monitored annually during the non - producing phase and semiannually during the production phase of <br />operations. The sampling frequency is shown in Table 25. <br />10.1.4 Groundwater Monitoring Procedures <br />Groundwater sample collection, sample handling, laboratory analysis, and field data collection are <br />conducted in accordance with strict environmental protocols for water quality sampling. All field sampling <br />instruments will be decontaminated and calibrated according to manufactures specifications prior to use. <br />A general site inspection will be performed upon arrival at each monitoring well and comments regarding <br />site conditions will be recorded on the field sampling sheet. Depth to water will be measured to the nearest <br />4148A.120927 <br />Table 25. Groundwater Monitoring Frequency <br />Whetstone Associates • <br />
