UH Manoa to conduct survey and assessment of underwater munitionsUniversity of Hawaiʻi at Mānoa
Vice Chancellor for Research and Graduate Education
The University of Hawaii at Mānoa has been awarded $1.975 million to support the U.S. Department of Defense‘s efforts to assess the potential risk to human health and the environment of an historic chemical warfare material disposal site about 5 miles south of the entrance to Pearl Harbor in waters greater than 1,000 feet deep.
A full array of state-of-the-art technologies owned and operated by UH Mānoa‘s School of Ocean Earth Science and Technology (SOEST) will be employed to assess the location and condition of the disposal site. The program will map the seafloor with high resolution sonar followed by direct observation of any sea-disposed chemical warfare material found using either remotely operated underwater vehicles or three-man research submarines deployed using UH research vessels.
Researchers will collect water, seafloor sediment and biological samples in the vicinity of the disposal sites and at control sites up-current and away from the munitions disposal site. Chemical analysis for munitions constituents, including military chemical agents, will be performed on sediment, water, and biological samples.
"The University of Hawaii is a recognized leader in the field of underwater research and has successfully partnered with the Department of Defense on previous research efforts, including a survey in conjunction with the National Oceanic and Atmospheric Administration (NOAA) of an underwater munitions disposal site off Oahu. I am confident that UH Manoa's leadership of this groundbreaking joint pilot project will succeed in establishing the preliminary procedures for determining whether sea disposed military munitions pose a hazard to human health and safety or adversely impact on the local marine aquatic environment," said Tad Davis, Deputy Assistant Secretary of the Army for Environment, Safety, and Occupational Health.
At the Department of Defense‘s request, the UH will also develop and prove out methodologies for surveying and sampling other historic munitions sea disposal sites. Between 1919 and 1970, the armed services disposed of military munitions and containers of bulk chemical agent in coastal waters off the United States, including the island of Oahu.
Dr. Gary Ostrander, UH Mānoa Vice Chancellor for Research and Graduate Education, praised the Department of Defense for its ongoing efforts to determine whether sea-disposed military munitions poses a threat to human health and the environment and for the selection of the UH as a partner, stating that the School of Ocean Earth Science and Technology has both extensive expertise and resources in underwater exploration and marine biology needed to ensure the program‘s success.
The program was funded through the efforts of Hawaii‘s Congressional delegation.
"This is a very important first step in determining the risks posed by military munitions disposal sites to our coastal waters," states U.S. Senator Daniel K. Inouye. Congressman Neil Abercrombie adds, "In taking the lead with this pilot effort we believe other states with similar sites will greatly benefit from the methodologies developed by the University of Hawaii."
The Department of Defense contracted the University of Hawaii to perform the program. The UH will partner with Environet, Inc., a local environmental consulting firm, to complete the assessment. Additionally, the National Oceanic and Atmospheric Administration will consult with the Department of Defense and University of Hawaii on scientific matters, and the U.S. Army‘s Edgewood Chemical Biological Center will provide chemical safety and analytical support to this project.
