A train derailment Sunday afternoon on a bridge crossing the Black River in Wisconsin dumped tons of coal in the water, leaving authorities to speculate about potential environmental damage.
Thirteen cars of a Union Pacific freight jumped the tracks in Oostburg, Wisconsin.
Collecting the damaged cars and repairing the tracks was accomplished Monday, cleanup of the spilled coal is expected to take longer.
A DNR spokesperson told WISN 12 News that a railroad contractor “is working on mitigation efforts to prevent migration of coal particulates further into area waterways.”
Short term coal dust could be a potential issue in river water, the spokesperson said.
