Slightly elevated levels of arsenic have been detected in the Waikato River, which is drawn on for water supplies in the Hamilton area.
Hamilton City Council, Waipā District Council and Waikato District Council have reported slightly elevated levels of arsenic in recent samples of treated water to Water Services Authority - Taumata Arowai. In Auckland, Watercare reported samples that meet drinking water standards.
Drinking water with slightly elevated levels for a short period of time is unlikely to impact people’s health. You do not need to boil your drinking water. It is safe to drink.
The Authority is monitoring the situation closely and will continue to work with the drinking water suppliers to ensure they are taking appropriate steps to manage and resolve the issue.
