Frequent measurements are required in the pumping well during the early stages of the test to define the drawdown curve. In addition to the electronic measurements,water levels will also be manually monitored periodically(at the end of each of the cycles described during the electronic data collection)using an electric sounding device. During the initial hours of the test, discharge will be monitored through the flow meter and recorded frequently until the discharge rate has stabilized. From there on,the discharge will be checked at least four times during the test using a 5-gallon bucket and a stopwatch. Test data will be recorded on field forms. 2.5 Task 5—Recovery Test Immediately after terminating the constant-discharge pumping test, the post pumping recovery test will begin. The recovery test will be conducted for approximately 12 hours or until the well has recovered to within 80 percent of the original drawdown. During the recovery test,water levels will be monitored in the pumping and observation wells at the same frequency as the constant discharge test. Completion of the recovery test will mark the end of the aquifer testing program. 2.6 Task 6—Water Disposal During the aquifer testing, groundwater will be stored in a Baker Tanks before disposal in accordance with local, State, and Federal rules and regulations. Disposal will require water quality monitoring during the test or at the end of the test. A minimum of two samples per test is anticipated in order to characterize the extracted groundwater before disposal into the City of Ripon non-potable water conveyance system located adjacent to the Site on Frontage Road. 3.0 DATA REDUCTION AND ANALYSIS The aquifer test data will be downloaded electronically and analyzed using the computer program AQTESOLV. This program provides a graphic display of the data and an on-screen visual matching of"type curves"to the test data. This procedure allows one to see the position of the type curves and the estimated aquifer properties throughout the analysis. The AQTESOLV program also provides the appropriate solutions for analysis. 4.0 REPORTING The results and analysis of the Aquifer Test Program will be provided in a technical memorandum. The memorandum will include a discussion of the testing procedures as well as a display of the tabular data and plots. Assumptions made in utilizing a particular method of analysis will also be discussed. Ripon Farm Services,Inc. 3 of 4 Aquifer Testing Work Plan July 2009
