Microbiological Water Quality Guidelines for Marine and Freshwater Recreational Areas
June 2003, Ref. ME474
These guidelines will assist councils/agencies to better inform their communities of the risks related to swimming at their bathing beaches. The Ministry of Health and the Ministry for the Environment consider it very important that councils are aware of their responsibilities and that the public are informed of the health risks in a way that is consistent with these guidelines.
They completely replace the 2002 version of the Microbiological Water Quality Guidelinesand all previous microbiological and bacteriological water quality guidelines.
The Ministry has received very useful feedback from agencies implementing the Guidelines. That feedback has been collated into a selection of frequently asked questions.
