A warning against using tap water in nine Jerusalem neighborhoods has been lifted for all areas except Abu Tor, the Jerusalem municipality announced Thursday morning.

The warning, in place since Wednesday afternoon due to the possibility of contamination, applied to the Old City, Baka, Abu Tor, Talpiot, Zur Baher, Silwan, Ras al-Amud, Mamilla and Morasha.

The Gihon Water Company and Health Ministry performed tests on the water Wednesday afternoon after it had been discovered that treated wastewater had leaked into the drinking water system, and later discovered that it had been a significant leak.

The municipality set up several stations in these areas for water pickup, and encouraged residents to bring their own bottles to the sites. Parents had been instructed to send their children to school with a bottle of water Thursday morning.
