Juliet Clague
BSc (Tech), MAppSc (Hons), PhD
Juliet is part of Lincoln Agritech’s Hamilton-based Environmental team, where she transforms complex soil and water science into practical tools for protecting New Zealand’s environment.
With a PhD in Soil Science from Lincoln University, Juliet specialises in groundwater and surface water quality and subsurface processes. Her research focuses on nitrate attenuation, denitrification, and the chemical pathways and transformations that influence water health.
Juliet’s work has advanced national understanding of nitrate pollution in groundwater systems. By applying isotopic methods and gas measurements, she identifies where and how denitrification occurs, giving councils and farmers science-backed strategies to protect waterways.
Focus areas:
- Groundwater quality monitoring and contaminant transport in the subsurface
- Denitrification processes, locating zones and measuring activity
- Surface water quality monitoring and data interpretation
