"Officials got their first complaints in 1979, when a Swannanoa resident complained of “foul odors” on his property. The resident complained to local, state, and finally federal authorities, citing open acid pits at the facility, one of which temporarily blinded his dog. In 1980 the EPA was involved, and in 1982 published the Chemtronics site on their proposed Superfund National Priority List (NPL)."
