Measuring Water Quality
Andriy Medvediuk - 123RF
How will we know if the actions people all over Aotearoa are taking to improve the health of our freshwater are working? Our research is striving to fill data gaps and build knowledge about how to measure and model water quality.

The implications of lag times between nitrate leaching losses and riverine loads for water quality policy
Understanding the lag time between land management and impacts on riverine nitrate–nitrogen (N) loads is critical to understand when action to mitigate nitrate–N leaching losses…
Guidance
Designing Freshwater Monitoring Programmes to Detect Early Improvement
This short guidance document is to support the design of freshwater monitoring programmes to detect early improvement and is for regional councils, government, and multi-agency…
Presentation
A Source-to-sink Contaminant Risk Framework To Support Water Quality Policy Across Scales
In the wrong place, or at excessive concentrations, nutrients (nitrogen and phosphorus) and sediment become contaminants. Along with pathogens, they require reduction to improve water…
Summary
Project Summary: Seeing, Understanding, Believing: A Farmer-Led Project into Waterway Improvement
This article summarises the results of a Rural Professionals Fund project that aimed to package practical methods for farmers to self-monitor waterway condition and ecological…
Journal Article
Towards implementation of robust monitoring technologies alongside freshwater improvement policy in NZ
International studies point out that some freshwater policy objectives are not achieved. This study describes that this is in part caused by shortcomings that include:…
Presentation
Mitigation action prioritisation & resource tool for freshwater farm plans
Freshwater farm plans will soon be compulsory for all pastoral farms larger than 20 hectares as part of the Government’s Action for Healthy Waterways reforms.…
Journal Article
Sediment and water-column phosphorus chemistry in streams at baseflow across varying catchment geologies
Streams can attenuate inputs of phosphorus (P) and therefore dampen the likelihood of ecosystem eutrophication. This P attenuation derives from many processes and remains poorly…
Technical Report
Measuring real time nitrate leaching from a tile drained Hawkes Bay onion field: Final report
The data showed a strong linear relationship between the N concentration measured by the sensor and in the grab sample (sensor N concentration = 1.09…
