PUBLIC NOTICE - South Waikato District Council Water Supply
The Ministry of Health has identified that some New Zealand waters are naturally acidic and can dissolve minute traces of metals such as lead, nickel and cadmium from plumbing materials while standing in plumbing fittings for several hours.
Recent tests have shown residents in the South Waikato District are supplied with such water. As a precaution, all households are advised to flush and discard at least half a litre of tap water each morning by running the tap for about 10 seconds before using their water for drinking, food preparation or cleaning teeth. This will ensure corrosion products that may have accumulated are washed away.
There are no lead fittings anywhere in the South Waikato District water reticulation system. There is no health risk related to this Ministry requirement.
