FORT WORTH, Texas (AP) — A boil water notice for parts of far north Fort Worth has been lifted after experts say supplies tested negative for potentially dangerous bacteria.

The Fort Worth Water Department on Friday rescinded the boil water order.

The advisory was issued early Thursday to boil water meant for drinking, cooking and making ice due to problems with a city tank. An operational error wrongly led to draining of an elevated tank and loss of water pressure.

The Texas Commission on Environmental Quality then required Fort Worth to issue the boil water notice for affected areas amid testing of supplies.

A city statement says 46 water samples were collected and all were negative for coliform bacteria. Crews restored adequate water pressure.
