Website Updated for 2007/08 Annual Review

This website has today been updated in line with the release on 26 November 2009 of the "Annual Review of Drinking-Water Quality in New Zealand 2007/08." This means that individual supplies (choose one on the Water Supplies tab) will show compliance for 2007/08.

The Annual Review is completed for 12 month periods from 1 July through to 30 June, rather than calendar years as was done until 2005. Data is compiled soon after each period ends. Data analysis by ESR follows, results are discussed with supplies where necessary, and a report is forwarded to the Ministry of Health for approval and eventual public release.

Individual supply compliance status is shown on this website once the report is public.

Compliance on this website is shown for treatment plants and distribution zones within each supply, but currently not for Priority 2 determinands - data on those can be found in the PDF report.
