Forty percent of people in New Zealand rely on groundwater for their drinking water, yet that water is vulnerable to contamination. 

Groundwater quality and management

Through an in-depth, research driven understanding of groundwater contamination processes, our team of groundwater scientists help clients to identify and address issues associated with landuse intensification and its effects on groundwater quality. We also design tools for water managers to enable them to assess, predict and minimise the impacts of land use, and landuse changes, on groundwater quality. 

ESR undertakes a national assessment of pesticide in groundwater, mainly on behalf of regional and district councils. We also undertake more general, ‘on-request’ assessments of regional groundwater quality for councils.

Groundwater scientists working together 

ESR, along with groundwater scientists at GNS Science (external link) , Aqualinc (external link) and Lincoln Agritech (external link) are working together, building on each other’s strengths, to improve the understanding and quality of groundwater research.
