GUMI, South Korea, March 23 (UPI) -- An acid leak at a plant in Gumi, South Korea, may have polluted the surrounding area, officials said Saturday.
Hydrofluoric, nitric and acetic acids were found leaking at the LG Siltron plant Friday -- the second time such a leak happened at the plant this month, Yonhap news agency reported.
Investigators said Friday's leak happened when a pipe carrying waste water from a conductor ruptured.
An employee at the plant said no one was injured in the incident.
However, local authorities are looking into whether the leak will have an environmental impact and to determine cause of the leak.
