July 1990 monthly report : Scientific Observation Hole (SOH) Program geothermal resource permit: GRP 89-1 Lilewa, Kapoho, and Halekamahina, Hawaii TMK: 1-2-10:01; 1-4-01:02; and 1-4-02:32

This document presents a monthly report to the County of Hawaii Planning Department to support the scientific observation hole (SOHs) program in the Kilauea middle and lower east rift lone. The SOHs are for scientific observation purposes only. The holes will not be flow-tested or produced. The information to be gained from the SOHs will provide an assessment of subsurface geological conditions, groundwater level and composition, temperature, drilling conditions, an inventory of possible mineral and geothermal resources, and an eruptive history of the island to the depth drilled. This report addresses: occurrence and duration of any start-up, shutdown, and operation mode of any SOH/facility; performance testing, evaluation, calibration checks, and adjustment and maintenance of the continuous emission monitor(s) that have been installed; and emission measurements
