Groundwater management

ESR's groundwater research team is recognised as a leader in the field, both domestically and internationally.

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 land use 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 land use changes, on groundwater quality.

Research snapshot

  • Our groundwater scientists are working with Rūnanga o Ngāi te Rangi and Ngā Hapū o Matakana me Rangiwaea as part of ESR's He Wai Māpuna programme. They're developing a wai programme for Matakana whānau that will include groundwater visualisations and groundwater monitoring on Matakana Island.
  • We're busy establishing a groundwater health index focused on the presence of macroinvertebrates in groundwater and microbial diversity.
  • We're contributing knowledge and design concepts for future public health programmes with and for countries in the Pacific region (from policy to practice). The goal is to empower them to achieve their goals for cleaner, safer drinking water and sanitation
  • ESR’s groundwater remediation research programme and work with experimental woodchip denitrification walls is gaining international attention. Our work was presented online at the AGU (Advancing Earth and Space Science) conference in New Orleans, USA in December 2021.

Groundwater scientists working together 

ESR, along with groundwater scientists at GNS Science(external link), Aqualinc(external link) and Lincoln Agritech(external link) also work together, building on each other’s strengths, to improve the understanding and quality of groundwater research. We call this the Groundwater Science and Research Alliance Aotearoa.
