The National Park Service (NPS), under the Department of the Interior, is seeking a Professional Deep Well Specialist for the rehabilitation of Well No. 2 at Yosemite Valley, Yosemite National Park, California.

  • Assessing and potentially replacing the well casing (187') and PVC pipe for the level transducer sounding tube due to age and glacial silt damage.
  • Re-installing all components and adjusting the shaft to optimum impeller clearance.
  • Remaining onsite during NPS personnel startup procedures to verify water production, amperage, and shaft stability.
  • Disinfecting the well and equipment in compliance with AWWA C654-03 (or most recent), sections 4.4, 4.5, and 4.5.1, specifically using the AWWA C-651 "Swab Method" with sodium hypochlorite. Flushing to achieve chlorine residual below 1.00 mg/L and dechlorination are required.
