Arsenic mobilisation during managed aquifer recharge
 Introduction
Mobilisation of arsenic during managed aquifer recharge (MAR) is an issue for schemes supplying drinking water. This research program aims to utilise advanced analytical tools for aquifer characterisation, speciation of dissolved arsenic and geochemical modelling to improve the current understanding of the mechanisms that control arsenic mobility in MAR schemes.
Objectives/Scope
To improve confidence in predicting and quantifying the processes that will impact on the quality of water recovered from a MAR scheme.
Activities
- Review suitable analytical techniques for understanding the mechanisms that control arsenic mobility in groundwater and incorporate into MAR trials
- Upgrade current PHT3D model capabilities to incorporate surface complexation modeling, enabling pH-dependent sorption of arsenic, and apply to a field data set
