Some Western Bay residents have reported stomach pains, rashes and puffy eyes after problems with their water supply.
On Tuesday, the Western Bay of Plenty District Council confirmed a high pH level in its water supply feeding about 300 homes in the Pongakawa and Paengaroa areas from Monday. Residents were advised not to drink or use the water.
The pH levels in the water supply were restored to recommended levels yesterday.
