Preconference Workshop

Quantification of sources and dynamics of micropollutants in urban sewer systems (uPW)

The main objective of the workshop is to pool knowledge on micropollutants in urban sewer systems and available datasets thanks to international research presentations and a large discussion on how to get and highlight data.

In more details:

• Learn about existing research being done on micropollutants (which substances are studied at an international scale and why those ones are chosen?)
• Share knowledge on monitoring issues for micropollutants
• Possibly leading to the development of a common monitoring protocol for micropollutants in urban water systems?
• Identify key research gaps in the area and collaborative opportunities.
• Evaluate the opportunity of gathering all available datasets and metadata in one base
• Submit an international publication and propose collaborations.

Please find in next PDF the detailed program with timetable.

Limits

Stormwater and wastewater systems will be the two main studied compartments. Treatment systems (WWTP or Stormwater systems treatments) are not considered in this workshop.

Workshop topics

1. From sampling to lab analyses: technical methods, i.e. what have to be taken into consideration in order to obtain results which are accurate for the required purpose. We can often learn from our mistakes.
   1. Representative event and pollutant loads (intra and inter-events)
   2. Sampling setup (time, flow proportional, devices) – materials used, sampling tubes (layout, slope, position in pipe, material, bottles, storage, sampling type (suction, peristaltic), 
   3. Analyses (devices, analytical limits…)
   4. Cleaning, blank procedures…
2. What and where are the available data?
   1. Which dataset (international and national)
   2. Results presentation for publication (ex: dissolved, particulate, total)
   3. Interpretation and comparison of methods

Workshop outline

Introduction (30 min)

• Micro and emergent pollutants
• definition: what do we include?
• What are the sampling issues?
• What about the data?

Invited presentations and discussions (15 min by presentation and 5 min questions) prepared following this template: 

1. Overview. Current micro-pollutant research being conducted by research institution. This overview should include: a brief description of the context of this research (i.e. why is it being conducted) and the critical research questions, the datasets created and any important findings/results.
2. Monitoring micro-pollutants. A detailed presentation of one (or more) aspects of the monitoring issues listed in the Workshop Topics above (e.g. how to correctly setup an automatic sampling system for micropollutants in urban sewer systems, or what are the uncertainties in analytical procedures, etc.).
3. Collaborative opportunities and research gaps. Identify where collaboration could be beneficial or where there is a need for research.

Institutions

Speakers will come from these different institutions (with name of potential speakers in brackets):

• DTU University, Danemark (Peter Steen Mikkelsen, Luca Vezzaro)
• Monash University, Australia (David Mc Carthy, Ana Deletic)
• Eawag, Switzerland (Christoph Ort, Jörg Rieckermann)
• INSA Lyon, France (Jean-Luc Bertrand Krajewski, Christel Sebastian)
• Paris Est University, France (Johnny Gasperi)
• University of Sheffield, UK (Adrian J Saul)

Group discussion (2 hours)

The second part of the uP workshop will be devoted to discussion. Depending on the number of participants, two groups will be created. (max 10 persons by group):

• The first one will deal with the methods for data acquisition (see workshop topic I: from sampling to lab analyses).
• The second one will be about the common presentation of available datasets. How to highlight the results and how to fill the gaps? (Example of Norman EU project)

Conclusions/outlook (1 hour)

Conclusions of the groups and uP workshop. Proposition of a date for the next uP workshop (Novatech 2013?)
