    Evaluation of major dike-impounded ground-water reservoirs, island of Oahu
    (U.S. Geological Survey, 1981) Takasaki, Kiyoshi J.
    "Ground-water reservoirs on Oahu store a very large but only approximately estimatable quantity of freshwater. These reservoirs include interconnected water bodies that are impounded by volcanic dikes or other geologic structures, and water bodies that are floating on saline ground water in dike-free Java flows in the flanks of the volcanoes. A significant amount of water is stored above sea level, to an altitude of at least 2,000 feet in the Waianae Range, but most is stored below sea level. The depths of freshwater storage below sea level range from a few feet to 1,000 feet or more in the dike-free lavas, and probably to several thousands of feet in the compartmented lavas between dikes. Other water bodies, smalI in comparison, are perched above and isolated from these interconnected bodies. "This report is primarily concerned with high-head dike-impounded ground-water reservoirs that underlie interior mountainous areas where rainfall and subsequent recharge to ground water are the greatest. These reservoirs, owing to their upgradient positions, play a very important role in the recharge, storage, movement, and discharge of alI ground water on the island."

    Potential effects of the Hawaii Geothermal Project on ground-water resources on the island of Hawaii
    (U.S. Geological Survey, 1994) Sorey, Michael L. ; Colvard, Elizabeth M.
    "In 1990, the State of Hawaii proposed the Hawaii Geothermal Project for the development of as much as 500 MW of electric power from the geothermal system in the East Rift Zone of Kilauea Volcano. This report uses data from 31 wells and 8 springs to describe the properties of the ground-water system in and adjacent to the East Rift Zone. Potential effects of this project on ground-water resources are also discussed. Data show differences in ground-water chemistry and heads within the study area that appear to be related to mixing of waters of different origins and ground-water impoundment by volcanic dikes. East of Pahoa, the ground-water system within the rift is highly transmissive and receives abundant recharge from precipitation; therefore, the pumping of freshwater to support geothermal development in that part of the rift zone would have a minimal effect on ground-water levels. To the southwest of Pahoa, dike impoundment reduces the transmissivity of the ground-water system to such an extent that wells might not be capable of supplying sufficient fresh water to support geothermal operations. Contamination of ground-water resources by accidental release of geothermal fluids into shallow aquifers is possible because of corrosive conditions in the geothermal wells, potential well blowouts, and high ground-water velocities in parts of the region. Hydrologic monitoring of water level, temperature, and chemistry in observation wells should continue throughout development of geothermal resources for the Hawaii Geothermal Project for early detection of leakage and migration of geothermal fluids within the groundwater system."

    Puna emergency response : report on the review of Hawaii County emergency operations plan and Puna Geothermal Venture emergency response plan
    (U.S. Environmental Protection Agency, Region 9, 2000-08) United States Environmental Protection Agency, Region 9
    "This report summarizes a review of emergency response capabilities for Hawai’i County and Puna Geothermal Venture (PGV). The U. S. Environmental Protection Agency (EPA) assembled an independent team of experienced individuals (the “Review Team”). EPA tasked them to review emergency response plans and conduct site visits and interviews. This project was a follow-up to the EPA’s 1995 compliance inspection of the PGV facility and a response to community requests. The purpose of the project was to provide an independent evaluation of the emergency response plans, with the long–term objective of preventing chemical accidents and improving emergency response capabilities. The review team conducted site visits in Hawai’i from August 5 through August 9, 1996. During that time, team members received information from state and local agencies, PGV, and the community (composed primarily of area residents). EPA held public meetings at the Pahoa Community Center and the University of Hawai’i, Hilo Campus Center to discuss the review. These meetings offered the review team an opportunity to meet with residents of the Puna area."

    Environmental assessment of an investigation of the hydrothermal system at Kilauea Volcano, Hawaii
    (U.S. Geological Survey, 1973-01) Tilling, Robert I.
    "A test well 3,000 to 5,000 feet in depth is proposed to be drilled 0.7 miles south of Halemaumau crater in Hawaii Volcanoes National Park, Island of Hawaii. It represents the first attempt to drill above a magma chamber of an active volcano to test the hydrologic and physical environment. Geologic and geophysical test will also be performed in the area.

    Summary of the biological information collected during the U.S. Fish and Wildlife Service's Hawaii Forest Bird Survey in the Puna study area on the island of Hawaii
    (U.S. Fish and Wildlife Service, 1985-05) Jacobi, James D.
    "This report summarizes the data collected during the RS. Fish and Wildlife Service's Hawai'i Forest Bird Survey (HFBS) in the Puna District on the island of Hawai'i, focusing on the lands owned by the James Campbell Estate and the State of Hawai'i in the Puna Forest Reserve and Wao Kele 'O Puna State Natural Area Reserve. The primary objective of the HFBS was to determine the current distribution, abundance, and status of the endangered native forest birds and their habitats on all of the major Hawaiian islands. Detailed information was also collected on the distribution of other native and non-native forest bird species, native plant species, and on introduced species of both plants and animals. Field work was conducted in the Puna area during the summer of 1979."
