LAREDO, Texas (AP) - A boil-water notice has been issued for the Texas border city of Laredo due to a low chlorine levels in the municipal drinking water supply.

Laredo Mayor Pete Saenz on Saturday night announced the boil-water notice for the city of about 260,000. He says routine testing of Laredo's drinking water found the city failed to maintain acceptable disinfection levels in parts of the system.

Saenz says there's no water shortage in Laredo but the chlorine issue means a potential health risk. The mayor had no timetable when the boil-water notice, issued as a precaution, will be lifted.

The Texas Commission on Environmental Quality required Laredo to notify all customers to boil their water until further notice. The notice applies to all consumption, including for cooking, personal washing and brushing teeth.
