This dataset was first added to MfE Data Service on 07 Apr 2020.

This indicator measures groundwater quality in New Zealand’s aquifers and how it is changing over time, based on measurements made at monitored sites. We report on nitrate-nitrogen, ammoniacal nitrogen, dissolved reactive phosphorus, chloride, conductivity and Escherichia coli (E. coli) including:

  • trends in concentrations for 10-year (2009–18) and 20-year (1999–2018) periods.

More information on this dataset and how it relates to our environmental reporting indicators and topics can be found in the attached data quality pdf.
