CHICO, CA - Cal Water found traces of low-level contamination in 11 of Chico's water wells.
The chemicals are called PFAS. They're a group of about 3,000 chemicals. And18 of them show negative health effects for people.
The effects range from liver damage, increased thyroid disease risk and even possibly causing cancer.
Cal Water Quality Program Manager Loni Lind said the PFAS chemicals can be found in food, clothes and now drinking water.
Lind said a couple of years ago Cal Water shut off two wells in chico after finding hazardous chemicals.
"The numbers that we got back are all in chico significantly lower than the response level so we don't have any ever that cross that response level and would be recommended that we take sources out of service or some action along those lines," Lind said.
When test results come back - they come back as either a notification level, a response level or higher levels.
Response levels suggest closing or treating a water source. A notification level warrants further monitoring of that well.
Lind said chico has tested all 56 wells: Zero came back over the response level and 11 came back over the notification level - but still under the response level.
Lind said those levels still aren't high enough to take action on and people in Chico should not be worried about drinking the water.
