This paper was presented to the U.S. Air Force Academy by an officer of the U.S. forces present in south Korea in 1997.

It disclosed that carcinogen 98 times the allowed level was detected in the U.S. military base in Puphyong at that time and the scrapped batteries were buried in the U.S. military base in Waegwan.

Oil in the underground oil tank north of the U.S. air force base in Kunsan overflowed, polluting the environment around it. An investigation into this pollution in 1997 led to the confirmation of the fact that carcinogen 13 times the allowed level was contained in the underground water and this contaminated underground water, particular, slowly flowed into the irrigation canal around the base.

110 million liters of oil leaked from the U.S. air force base in Osan due to the explosion of the oil tank in 1986, polluting underground water. In 1996 the U.S. forces unit side there banned its troops from drinking underground water.

The paper also deals with the environmental pollution in U.S. military bases in Uijongbu, Tongduchon and Phyongthaek of Kyonggi Province, Chunchon of south Korean Kangwon Province and other places.

What matters is that the U.S. imperialist aggression forces have kept all this secret till now.

The disclosure of more facts about the U.S. forces' environmental pollution helps estimate enormous damage done to south Koreans living around their base.
