The evaluation was conducted to determine the current condition of the well and, if possible, what impact the accumulation of sediment has had on the performance of the well. The evaluation was conducted to establish a baseline for the current condition of the well and, if possible, what impact the accumulation of sediment has had on the performance of the well. In order to establish trends for well performance periodic testing is required at 6 month intervals for the first year and annually thereafter. In order to continue to evaluate the performance of the collector well as the sediment from behind the dams continues to wash down the Elwha River, it is recommended that long-term monitoring of water levels within the aquifer be conducted along with periodic testing of the collector well completed. To accomplish this, the Consultant will perform the following tasks: Task 5: Installation and Mo -13 Activities: The Consultant shall install water level recorders (In-situ LevelTrolls or equivalent) in Observation Well 1 (OW1-13) 13 and OW2-13. The water level within the collector well and the elevation of the Elwha River will also be measured during this period. The data recorded shall be downloaded every two weeks, with manual water level measurements made at these times to confirm proper operations of the water level recorders. These units will allow the water level/recharge trends within the aquifer to be evaluated as well as the efficiency of the collector well. The recorded water level data shall be reviewed quarterly by the Consultant's hydrogeologist experienced in collector well evaluations. Assumptions: • The collector wells' existing water level indicator in the collector well and the USGS Elwha River at the Diversion gauge can be utilized. • The City shall provide a laptop computer and communication cable to download the water level recorder. Professional Services Agreement, Page 3 2/24/2012 Project 06-01, Amendment 1 • The City will provide a manual water level measuring tape, Solinst Water Level Meter Model 101 or similar. • The City will purchase the water level recorders for OW1-13 and OW2- 13. Complete units will require twist lock cable, well dock and troll Com with software. • The Consultant shall provide assists and training in the use and installation of the water level recorders. • The City shall establish at the upstream wing wall a benchmark to allow for the manual measurement of river level elevations. • Quarterly review shall be completed by the Consultant's Hydrogeologist. Deliverables: 1, Memorandum of Results Task 6: 24 to 48 Hour Constant-Rate Test of the Collector Well Activities: A 24 to 48 hour constant-rate test of the collector well shall be conducted at a lower rate (approximately 4000 gpm) to observe the drawdown trend at the end of the test to provide an accurate assessment of the current capacity of the well. This rate is consistent with the rate utilized during the 1994 extended pumping period testing of the collector well; which will allow the Consultant to make comparisons between the two tests. Additionally, the Consultant shall provide detailed procedures for the step-drawdown performance testing prior to testing. Assump pns. • The water level recorder shall be installed before this test is conducted to evaluate background trends prior to testing. • City staff will perform the a step-drawdown performance testing similar to that recently completed (excluding the underwater inspection). While the sediment continues to be transported down the Elwha River, the step drawdown tests shall be conducted every six months for a period of one year and annually thereafter. The City shall provide the water level data to the Consultant for evaluation. • The test of the collector well shall be conducted in either January or February 2014 with the next test approximately six months thereafter (July or August 2014).
