Workers with a Lee Memorial Hospital contractor dumped industrial dye into a storm drain in Naples, Fla., that leads to a creek flowing into the Caloosahatchee River, according to an article on the Naples Daily News website.
The dye, a non-hazardous tracer chemical used in hospital mechanical systems, caused the water in the creek to turn red.
Hospital crews are working with the contractor on cleanup.
A safety sheet provided by the company describes the chemical as non-flammable, non-carcinogenic and a "low" hazard for humans.
