A chemical leak triggered a big scare at a water treatment plant in Northern California.

Fire crews said about 11,000 gallons of sodium hypochlorite somehow spilled from its tank. It then leaked through another concrete tank that was cracked.

Hazardous material crews shoveled dirt to keep the liquid from going into the soil.

The rest of the chemical was pumped into portable tanks.

Responders said the water supply was not contaminated.

Sodium hypochlorite is used as a disinfectant.
