Understanding the fate and transport of selected biomarkers in sewers
The ARC Discovery Project aims to improve estimates of population drug use and chemical exposure by systematically studying the fate of drugs, organic pollutants (e.g. pesticides) and human biomarkers in sewers. We will combine advanced experimental sewer research facilities with an outstanding analytical set-up and excellent modelling expertise to address critical gaps in our knowledge of the fate of chemicals in sewers. The information will be used to provide accurate, cost-effective and near real-time estimates of chemicals entering the sewer system that will allow us to better estimate changes in population drug use, chemical exposure and health status.

Project Outcomes
Investigations of the biodegradation of illicit drugs and other biomarkers were conducted in lab-scale sewers under different conditions. A field study was carried out at a sewer site of the Gold Coast City Council in 2016.
