Seoul and Washington start taking groundwater samples near Camp Carroll in Chilgok, North Gyeongsang Province on Friday to investigate claims that the U.S. Forces Korea buried drums of the lethal defoliant Agent Orange there in 1978.
The two countries reached the agreement in a marathon eight-hour session of the environment subcommittee of the Korea-U.S. Status of Forces Agreement Committee at the U.S. garrison in Yongsan, Seoul on Thursday.
The National Institute of Environmental Research is to take groundwater samples at 10 locations near the camp. U.S. officials will also join the NIER researchers.
Once an American environmental expert arrives, the two countries will set up a joint investigatory team and start investigating inside the base.
