Groundwater dashboard

The Groundwater dashboard provides a tool for assessing the likelihood of detecting a reduction in nitrate concentration in existing monitoring wells.

The Groundwater dashboard comprises an interactive map populated with information and modelling results from approximately 950 regional council monitoring wells.

The output of the Groundwater dashboard is the detection power (likelihood of detecting the reduction in nitrate) for each existing monitoring well in the region, based on the selected sampling duration and frequency.

The WebApp can be used in conjunction with the report Water quality monitoring for management of diffuse nitrate pollution and the Groundwater Detection Power repository to assist with the evaluation and design of groundwater quality monitoring networks for detection of water quality change.

Likelihood of detecting improvement in nitrate concentrations in existing wells

What you can use the WebApp for

Examples of applications of the Groundwater dashboard include:

  • A regional council wishes to track progress towards nitrogen discharge reductions to a lake but cannot monitor this directly in the lake due to lag times. Staff need to know where to monitor groundwater within the catchment, at what frequency, and for how long, to determine whether land use mitigations are having the expected effect.
  • A catchment group wants to know whether nitrate loss mitigations being implemented by farmers in a hill-fed river catchment are likely to achieve the nitrate concentration reduction target in the river. River nitrate concentrations are highly variable, which makes it difficult to track progress via river nitrate monitoring alone. They wish to know where and how to monitor groundwater to track the effectiveness of mitigations.
