Two geothermal scientific wells in Pahoa will be plugged and abandoned.

The Department of Land and Natural Resources has contracted Water Resources International to plug and abandon SOH-1 and SOH-2 located in Pahoa.

Drilled in 1991 for research purposes to monitor temperature gradients down the shafts, the two wells are no longer being used by the University of Hawaii or DLNR for geothermal resource monitoring purposes.

Representatives from the department’s engineering division, consultant Brown and Caldwell, and Water Resources International will attend the Puna Geothermal Venture’s community meeting scheduled for Thursday, Dec. 8, from 6-8 p.m. at the Pahoa Community Center to answer any questions on the project.

Initial site clearing and preparations are now ongoing at the site of SOH-1, and around December 12, work will begin on plugging the well and restoring the area, with SOH-2 to follow in a similar manner.

The project is expected to be completed in approximately 3 months. Work hours will be limited to between 7 a.m. to 7 p.m. daily.

The contract award amount for the plugging and abandonment of the two wells was $2,036,000.
