A tanker carrying fracking fluid rolled over in the Poudre Canyon in northern Colorado, spilling some the fluid.
The Fort Collins Coloradoan reports that the Colorado State Patrol says the accident occurred about 11 p.m. Thursday on Colorado 14 and required a hazardous waste team to clean up the spilled fluid.
It wasn't immediately clear how much fracking water was spilled or whether the spill reached the Poudre River.
Trooper Gary Cutler says the truck's driver was not hurt. No other information, including whether the driver was cited in the crash, was available Friday.
