This paper presents an overview of the chemical results of the Premiers Collaborative Research Project: Characterising Secondary Treated Wastewater for Drinking Purposes Following Reverse Osmosis Treatment. The chemical groups analysed include a broad range of analytes with different physical and chemical characteristics and toxic effects. Their potential human health impacts at the concentrations observed in the post RO water were evaluated using a screening health risk assessment methodology. The results confirm that reverse osmosis is effective in controlling chemical hazards and reliably producing recycled water suitable for augmenting, through indirect potable reuse, public drinking water supplies. Specific health recommendations, detailed in the technical report, were developed for the monitoring of the Water Corporation's three-year groundwater replenishment trial.
