Raw data, and state and trend calculations for key groundwater quality indicators, including nitrate-nitrogen, ammoniacal-nitrogen, dissolved reactive phosphorus, dissolved iron, dissolved manganese, total dissolved solids content, and electrical conductivity.

Statistics reported on include:
- median and median absolute deviation
- percentiles
- trend magnitudes
- statistical test p-values (from the Mann-Kendall trend test, Kruskal-Wallis test for seasonality, and sign-tests and Wilcoxon rank-sum tests for distribution differences).

The following report and spreadsheets relate to the "Ground water quality" measures on the Environmental Indicators, Te taiao Aotearoa website:
- Moreau M, Daughney C, 2015. Update of National Groundwater Quality Indicators: State and Trends December 2004-2013, GNS Science Consultancy Report 2015/16. 38 p.

"Freshwater plant and animal pests can have significant negative impacts on ecosystem health by reducing indigenous biodiversity through predation and competition, and destabilising aquatic habitats. Freshwater plant pests can cause economic losses through blocking water intakes for hydroelectricity generation, impeded drainage or irrigation. In addition, pests can affect the suitability for recreational activities.
This dataset relates to the "Freshwater pests" measure on the Environmental Indicators, Te taiao Aotearoa website. "
