6th International Conference on Testing the Waters (TTW6): The International Conference on Wastewater Surveillance

Cranfield University hosted the 6th International Conference on Testing the Waters (TTW6) in Oxford in June 2023. Since TTW1 in Lisbon in 2013, it has been held in Queensland, Australia (2021)Foshan, China (2019); Lisbon, Portugal (2017); and Ascona, Switzerland (2015). TTW has been, from the outset, uniquely focused on wastewater-based epidemiology (WBE). The event was initiated by the EU SCORE sewage network and the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA), both having a focus on biomarkers of chemicals monitoring and management.

Conference theme

Advances in wastewater-based epidemiology:

Recent developments in the measurement of new markers of population health, exposure and activity in wastewater.

Linking wastewater analysis with public health management:

Large-scale monitoring programmes of drug, disease and/or exposure control authorities, evaluation of policies using wastewater monitoring data, cultural and legal aspects of drug monitoring.

New applications and future perspectives:

Bridging WBE and other data sources, early warning of new substances via wastewater analysis.

Dr Teemu Gunnar
Finnish Insitute for Health and Welfare, Finland

Teemu Gunnar is a head of the Forensic Chemistry Unit at the Finnish Institute for Health and Welfare. His unit is, among other tasks, responsible for nationally-centralised toxicology for all post-mortem, driving under influence and prison cases in Finland, as well as the WADA-accredited doping analyses and biomarker analytics. He has been the principal investigator for nationwide illicit drug monitoring through wastewater-based epidemiology (WBE) for over 10 years, and has consulted various countries on the aspects of WBE. He is also a member of the Finnish Coordination Group on Drug Policy. He received the International Association of Forensic Toxicologists (TIAFT) Young Scientist Award in 2005 and the Finnish Medical Society award in 2017 – the latter concerning publication on WBE studies.

Keynote title: The role of wastewater-based epidemiology for illicit drug monitoring and combining information with other data sources

Professor Davey Jones
Bangor University, UK

Davey Jones holds a Professorial Chair in Soil and Environmental Science at Bangor University. A major focus of his research is on understanding human pathogen behaviour in water-food-soil-plant-microbial systems. He currently co-leads the wastewater-based public health monitoring programme in Wales. 

Keynote title: Wastewater monitoring in Wales: transitioning from public health to One Health.

Professor Kevin Thomas
University of Queensland, Australia

Professor Kevin Thomas is Director of the Queensland Alliance for Environmental Health Sciences (QAEHS) at the University of Queensland, Australia. Kevin is an environmental health scientist with a particular interest in understanding the environmental exposures associated with contaminants of emerging concern (CECs) with the goal of protecting environmental and human health.

His current research is focused on understanding human exposure to plastics pollution and developing mass spectrometric analytical methods for characterising plastics and other CECs. His team is focused on assessing community-wide health status through analysing wastewater (wastewater-based epidemiology), establishing alternative approaches to exposure monitoring, for example, explanted silicone prostheses and wristbands and better understanding how plastics cycle in the environment with the aim of reducing exposure.

Author of over 300 peer-reviewed papers and Associate Editor for the Journal Science of the Total Environment, Kevin is a strong collaborative researcher, having co-founded the international SCORE network on sewer biomarker analysis for community health assessment.

Keynote title: From niche to mainstream and beyond for WBE
