Annual Review of Drinking-Water Quality in New Zealand 2005

Date of publication: January 2007


Summary

This report covers the fourth and final year when the microbiological and chemical quality of drinking-water was assessed using the Drinking-Water Standards for New Zealand: 2000 (DWSNZ:2000) and is the third year when both microbiological and chemical compliance are addressed in the same report.

Such reports have been published on annual basis since 1994.

The information on the microbiological quality of drinking-water was obtained through the public health units of the district health boards (DHBs) using questionnaires that sought data concerning surveillance and monitoring programmes carried out by DHBs and water suppliers, respectively. Water suppliers fall into two groups: local authorities (LAs), including commercial water supply companies contracted by LAs, and private organisations or communities responsible for the operation of their own drinking-water supplies, of which schools have been considered separately. Water suppliers are responsible for water quality monitoring, whereas the DHBs carry out surveillance of the management of drinking-water quality in the health districts.

The survey sought information about both distribution zones and water treatment plants. In addition to microbiological and chemical quality information, the questionnaire sought information about the water treatment processes in use and the means used to demonstrate compliance with the DWSNZ:2000.

The report contributes to the fundamental principles in the New Zealand Health Strategy of ‘good health and well-being for all New Zealanders throughout their lives’ and ‘an improvement in health status of those currently disadvantaged’. The report also directly encompasses the New Zealand Health Strategy Goal 4: ‘A healthy physical environment’ as well as Objective 17: ‘Support policies and develop strategies and services that ensure all people have access to safe water supplies and effective sanitation services’.
