Regional spreadsheets
The following map provides links to spreadsheets with summary data tables for each region (and one table for New Zealand that combines regional data) for six water quality indicators: nitrate, E.coli, ammoniacal nitrogen, iron, manganese and electrical conductivity. Each regional spreadsheet contains data for:
- the number of sites exceeding water quality guidelines for each year in period 1995-2008
- percentiles for each year, and
- trend categories for the whole period.
A national summary is also available.
