The Edendale Aquifer Group is adopting a community-wide approach to tackling challenges in our catchment. This foundation project focuses on understanding how nutrients, particularly nitrogen, move and interact within our waterways, aquifer, and landscape.

Using high-resolution data, we are analysing the landscape factors that influence groundwater discharges. This helps us better understand the catchment’s challenges and identify the best areas for nitrate mitigation.

Key Milestones so far

• Workshop with Dr Clint Rissman (Land and Water Science): Dr Rissman guided us in understanding how the landscape affects water quality. He has since developed a technical document identifying key areas for targeted mitigation.

• Farm Modelling with DairyNZ: We partnered with DairyNZ to model four farms in the catchment. Together, we are exploring practical options like using plantain to reduce nitrate losses while maintaining successful farm operations.

• Portable Nitrogen Testing: With the support of local businesses, we purchased a portable nitrogen tester. This tool gives us near-instant nitrate readings from bores, springs, and streams, allowing us to track trends and build valuable data.

This project is truly by the community, for the community. All data collected is managed responsibly, staying within the Group unless express permission is granted.

We’re incredibly proud of what’s been achieved so far and are excited to see more members of our community join us in creating meaningful change.
