The EPA is finally moving to clean up a Cass Lake, MN superfund site at the former St. Regis Paper Co. location in Cass Lake, which closed in 1985, which is contaminated with creosote.
Creosote is a wood-treatment chemical that is toxic.
But what is creosote?

Creosote is made from the distillation of tar from wood or coal and is used as a wood preservative. If you have seen railroad ties and utility poles, you have seen, and smelled, wood treated with creosote.
It has been used as a wood preservative since the mid-1800s.
The EPA does not consider that creosote as a risk to the general public.
But "Creosote may pose risks to fish and invertebrates when creosote-treated wood is used in aquatic and railroad structures."
The Cass Lake community is abandoned due to creosote pollution at very high concentrations.

Other sources do indicate that creosote exposure, especially prolonged contact or drinking water contaminated with creosote, can cause health impacts. The health impacts include different forms of cancer. At elevated concentrations irritation & similar are possible.
