Levels of trihalomethane, a byproduct of using chlorine to disinfect water, are higher than the standards in two places, said lohud.com.
The affected treated water is from Lake DeForest reservoir, supplier of drinking water in Rockland to 300,000 customers, according to lohud.com.
The chemical's average levels were 80.6 parts per billion and 84.2 ppb, a little higher than the 80 ppb U.S. Environmental Protection Agency standard, according to water provider Suez, lohud.com reported.
Hydrants are being flushed and groundwater is being used over surface water since the middle of March, said lohud.com.
