LOUISVILLE, Ky. (FOX 56) — Louisville Water Company is telling customers their water is safe to drink after the train derailment in northeast Ohio.

According to Nexstar’s WKBN, the Norfolk Southern train — which totaled around 50 cars — derailed around 9 p.m. Feb. 3, along the east-west tracks that run through East Palestine, Ohio. Federal investigators said a mechanical issue with a rail car axle caused the fiery derailment near the Pennsylvania state line.

Cars involved contained vinyl chloride, combustible liquids, butyl acrylate, benzene residue, and nonhazardous materials such as wheat, plastic pellets, malt liquors, and lube oil, Norfolk Southern said in a statement.

There were fears that chemicals released into the Ohio River after the derailment might cause a problem downstream.

Scientists with Louisville Water studied the size and location of the spill and calculated the travel time of the spill to Louisville. In turn, they have determined the water is safe to drink.

Officials said customers may notice a minor odor in the water, but conventional water treatment will minimize taste and odor concerns.

Testing of the water is ongoing, according to Louisville Water.
