High ranges of two most cancers inflicting chemical compounds have been detected in groundwater operating below the Marine Corps Air Station Futenma on Okinawa, in accordance with Japanese officers.
The chemical compounds that are utilized by the US navy have been banned in Japan
The Pentagon just isn’t permitting Okinawan officers on base to research.
The carcinogenics perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) have been present in excessive concentrations in underground water throughout surveys in August and January, the Okinawa prefectural authorities’s environmental safety division stated in a press release.
“High levels of contamination was detected in underground water samples taken from the Oyama and Kiyuna districts,” stated Yoshinari Miyahira, group chief of the environmental safety division’s water environments management group. “Both sit on lower grounds adjacent to Futenma.”
Japan banned the manufacture and importation of each chemical compounds in 2010. They are artificial, absolutely fluorinated natural acids which have been linked to tumors, will increase in physique and organ weight and loss of life in animals, Okinawan officers stated. PFOS and PFOA are utilized in firefighting foam, plane grease, water-repellant supplies and fluorine chemical compounds.
Despite the ban, although, the chemical compounds have been found close to each Futenma and Kadena Air Base, additionally on Okinawa. PFOS was discovered downstream of Kadena final 12 months, resulting in the 2 checks.
In August, three of the 35 places monitored by Okinawan officers exceeded US consuming water well being advisory ranges of zero.07 micrograms per liter. The three places had 1.three, zero.21 and zero.71 micrograms respectively, and have been all adjoining to and downstream from Kadena. In January, PFOS was present in six of 41 places within the prefecture, with ranges ranging between zero.11 and zero.88 micrograms.
“The concentration of the substances is notably high in the vicinity of the downstream area of the air station,” Miyahira stated. “Meanwhile, samples taken at higher grounds of the air station detected lower levels of the substances.”
Last April, a Freedom of Information Act request by MuckRock revealed a spate of accidents at Futenma over the earlier 15 years that spilled at the least 21,000 liters of fireside extinguishing brokers, though not the entire chemical compounds have been deemed hazardous.
It is unclear what brought on the present contamination close to Futenma. While Okinawan officers are monitoring the scenario, they’re unable to find out the wrongdoer as a result of the US Marine Corps gained’t allow them to on the air station to research, Stars and Stripes reported.
“We have asked the military through the Ministry of Defense to provide us with information on the history of the use of the agents that contained the substances and a trilateral [on-base] survey by the prefectural government, the military and the Ministry of Defense,” Miyahira stated, referring to the US Department of Defense. “We received a [ministry] response that the military handles the agents appropriately and that they see no need to conduct the proposed survey.”
Despite the presence of the chemical compounds in groundwater, water stays secure to drink, in accordance with a spokesman from Ginowan City’s water bureau. The Chatan Water Treatment Plant serves each Kadena and the encircling areas. The acids additionally haven’t appeared in crop samples, Miyahira stated.
