ES&T’s Best Papers 2013: Two SEWPROF members among co-authors

ES&T first pageThe journal Environmental Science and Technology (ES&T) selected 15 articles for the best papers 2013. In the category Environmental Technology Jake O’Brien’s (UQ/Entox, Australia) manuscript, with Jochen Mueller (also UQ/Entox, Australia) and Christoph Ort (Eawag, Switzerland) amongst the co-authors, was third-runner up.

The manuscript describes an innovative method to estimate the number of people who contributed to a wastewater sample. Measuring multiple pharmaceuticals in wastewater allows reliably quantifying day-specific population sizes and realistic uncertainty estimates thereof. These are important numbers to calculate population-normalized drug loads in wastewater-based epidemiology.

On 21 October 2013 in Bern, Switzerland, the td-net (Network for Transdisciplinary Research) honoured recent developments and ongoing collaborations in the field of wastewater-based epidemiology. The td-award recognises an outstanding trans-disciplinary approach pushing boundaries of trans-disciplinary research.

The team of applicants lead by Christoph Ort (Eawag, Switzerland) involved nine scientists from SEWPROF ITN.

The jury from the td-net evaluates projects related to framing a complex problem, co-production of knowledge between disciplines, inclusion of stakeholders, scientific rigour and societal relevance.

Key challenges in the sampling and analysis was the focus of the second SEWPROF training event that took place in Oslo on Monday 9 and Tuesday 10 September 2013. The aim of the event was to provide the early stage researchers with an understanding of the different factors that may influence the quality of their raw data and how important this aspect is with regards wastewater analysis.

The first day focused on the different aspects around wastewater sampling and sample handling, including practical and theoretical approaches. Day 2 started with a site visit to VEAS wastewater treatment works where the researchers were told about the history of the plant, how wastewater is collected and transported to the plant and how it is treated before discharge into the Oslofjord.

For some early stage researchers, this was their first visit to a treatment plant and an insight into the scale of operation when treating the wastewater from a large city. Following lunch the researchers gave presentations of their individual projects and discussed the interactions and possible synergies with other partners.

Marie Mardal, SEWPROF’s Early Stage Career Researcher and ESRs’ representative to SEWPROF Supervisory Board said: “ESRs found a better understanding of what our respective projects were about and what possible collaborations we could make within the network, particularly for our secondments. There were plenty of opportunities to discuss with and learn from researchers who are more experienced within this field of research. We were given feedback from researchers working with complementary angles on the project, making us think of our research from new perspectives and keeping us within the frames of the project.”
