Theme 9: Environmental geochemistry and the regolith

Regolith science is an important, yet frequently ignored, component of environmental management in urban, rural, industrial, rangeland and arid environments. The geochemical and biogeochemical processes involved in regolith-groundwater interactions control the transformations and accumulations of chemical compounds, including deleterious metals, in groundwater. An important question is the relative role of biological versus non-biological processes and this can be addressed by molecular genetic attributes of the microbiota. Regional baseline geochemistry datasets, modified in concept from those used in mineral exploration, are essential for environmental monitoring. Regolith geochemistry can create a paradigm change in environmental health research in Australia.
