A boil water advisory has been issued for the borough of Stockton in Hunterdon County.
"Do not drink the water without boiling it first," warns the county's department of public safety.
On Monday, samples collected from the Stockton Borough Water Company's well No. 3 tested positive for a fecal indicator (E. Coli.).
Until further notice, residents are advised to bring all water to a boil, let it boil for one minute and then let it cool before using. Boiling kills bacteria and other organisms in water.
Residents also have the alternative of using bottled water.
Boiled or bottled water should be used for drinking, making ice, brushing teeth, washing dishes and food preparation until further notice.
Sampling and testing will continue, and the advisory will be lifted when the results permit such action.
Anyone seeking additional information can contact the borough at 609-397-0070.
