Havasupai Bar Four Well Evaluation and Rehabilitation

appears the last time the pump has been operated since then was in May 2002 for collection of a water sample. Several other water samples have also been collected since the well was installed. NRCE inspected the well in 2007 and in 2013. The pumpjack appears to be serviceable and in good condition. The condition of the pump barrel is unknown, and due to infrequent operation, may have suffered corrosion and deterioration since its last operation. It is therefore necessary to operate the pump in order to identify any problems that need to be repaired prior to placing the system in full-time operation. There is currently no source of power at the site to run the pump motor. The Havasupai Tribe propose to conduct a service and test run of the Bar 4 well before moving forward with the proposed development of the Bar 4 residential community and to enable routine sampling of the well. The approach for rehabilitation of this well is broken into five tasks. The outcome of each task dictates the necessity of and requirements for subsequent tasks. The tasks are: Task 1 Startup test and operation of well Task 2 Pumpjack service (surface equipment) Task 3 Power Supply Task 4 Water analysis Task 5 Report
