Check before you swim

In general, water can be contaminated and unsafe for swimming if:

  • there is a warning sign erected indicating water is unsafe.
  • there has been heavy rain recently.
  • the water looks dirty (murky).
  • there are several potential sources of contamination nearby and upstream such as:
    • houses on septic tanks;
    • stock with access to the water; or
    • a sewage treatment plant discharge. 

Who to contact

NRC are responsible for routine surveillance monitoring. These results are sent to the District Councils and Northland Health, who then carry out follow-up sampling as required and warn the public of any swimming sites that may be unsafe.

For information about a specific area or a warning sign contact your local District Council or the on-duty Health Protection Officer at Northland Health.
