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.

Transport and potential attenuation of nitrogen in shallow groundwaters in the lower Rangitikei catchment
Intensive agricultural activities are generally associated with nitrogen leaching from agricultural soils with potential to contaminate groundwater and surface waters. We studied nitrogen losses and…

Technical Report
Measuring actual denitrification to understand nitrogen loads through aquifers
Ne is an inert, soluble, gas which is present in air and has been used in international studies to understand recharge conditions. The aim of…
Technical Report
Efficacy of subsurface denitrification to attenuate nitrate in shallow groundwaters
Our preliminary results indicate occurrence of complete ‘benign’ denitrification in the reducing shallow groundwater sites with lower dissolved oxygen (DO) contents (DO < 1mg L-1),…
Technical Report
Collaborative expert judgement analysis of uncertainty associated with catchment-scale nitrogen load modelling with OVERSEER
The widespread view that use of OVERSEER-derived N loss estimates to set catchment-scale nutrient limits is an inappropriate use of this tool needs to be…

Journal Article
Soil hydraulic modelling outcomes with four parameterization methods: Comparing soil description and data inversion approaches
Different methods for parameterizing soil hydraulic models can lead to substantially varied predictions of soil–plant–atmosphere water fluxes. This study investigated, for a heterogeneous stony soil,…

Integrated landscape mapping of water quality controls for farm planning – applying a physiographic approach to the Waituna Catchment, Southland
Living Water (a Fonterra and Department of Conservation partnership) commissioned a high-resolution physiographic assessment of the Waituna Catchment, Southland, to support water quality and biodiversity…
Journal Article
Indirect faecal source tracking methods to elucidate critical sources and contaminant transfers through catchments – a review
In New Zealand, there is substantial potential for microbial contaminants from agricultural fecal sources to be transported into waterways. Understanding contaminant transport pathways from catchment…
