Groundwater quality
https://archive.gw.govt.nz/groundwater-quality
Groundwater in the Wellington Region is highly valued, especially for drinking water supply and irrigation.
In many areas, groundwater is linked to surface water bodies including rivers, lakes and wetlands. The successful protection of these waterbodies also requires careful management of our groundwater resources.
We monitor groundwater quality at a number of sites across the region. Key monitoring results and highlights are presented in our annual report cards (see below).
