Chemicals are continuously produced for various beneficial purposes, such as protecting crops, conserving food or treatment of diseases. Many of these chemicals and their transformation products enter the aqueous environment during their life cycle. This causes increasing concern for the public, regulators and users of surface water. So water authorities and drinking water companies are challenged with the question if, where and how to abate emerging contaminants in the urban water cycle. Many parties and stakeholders are involved: drinking water companies, water boards, the agricultural industry, the pharmaceutical industry, etc. In addition, emerging substances in the urban water cycle is a transnational problem: the problem doesn’t stop at regional or national borders. Water basins like the River Rhine and River Meuse cover several countries, so taking measures in one region or country will not solve the problem. The river basin body of the Rhine responsible for the water quality (IAWR), the Muese (Clean Muese Watercycle) and Drinking water companies from these countries as case holders. A keynote will explain the challenge from the river basin perspective. An international cooperation (Abates) will bring in an approach how to find the best point of engagement in the watercycle to take measures and the need there still is for more knowledge and data. A panel will discuss this needed follow up with representatives of knowledge institute, utility, water authority and industry will discuss this.

The presentation will give recent examples for micro-pollutant occurrence in river Rhine and its tributaries. Occurrence data for different parts of the water cycle will be presented as well as information on sources and behavior of the compounds in the environment and during technical treatment steps applied in waterworks. Possible strategies for drinking water utilities to deal with micro-pollutants in their source waters will be proposed.

The Berliner Wasserbetriebe as the municipal water supply and waste water company for Berlin’s 3.6 Mio inhabitants has been dealing with organic trace substances in water resources for decades. Due to progress in analytics and increasing use of pharmaceuticals, industrial chemicals, detergents etc. their detectability has increased significantly in the past. Focusing on waste-water-related substances, the Berliner Wasserbetriebe have developed a strategy for managing the urban water cycle in order to minimize the occurrence of relevant substances in drinking water. This strategy relies on a combination of prevention, decoupling of drinking water resources from urban influences and technological barriers.

Two recent cases of chemical pollution in Dutch sources for drinking water are presented. In the summer of 2015, a unknown pollutant in the river Meuse, which was later identified as pyrazole, was detected. And more recent FRD-903, a perfluorinated compound that is released when GenX-technology is used. The source tracking, monitoring data, and the removal efficiency in the drinking water treatment process of these emerging substances will be discussed.

A new approach in public health epidemiology utilising urban water profiling for health biomarkers has been recently pioneered to provide near real-time measurements of public health. Although still in its infancy, this approach is currently used to determine community-wide illicit drug use trends via the analysis of urinary drug biomarkers in wastewater with the usage of cutting-edge chemical and bio-analytical techniques. Research has been undertaken by the SEWPROF European Consortium (www.sewprof-itn.eu) and COST Consortium (www.score-cost.eu) to identify and validate new specific biomarkers in order to provide comprehensive information on community-wide health and improved risk assessment with the ultimate goal of disease prevention. This talk will introduce the concept and its rapid advances. It will focus on pharmacologically active compounds in urban water and their stereochemistry in the context of environmental and public health. It will also explore new avenues in the utilisation of urban water fingerprinting in the assessment of population health and health risk prediction.

Chemical analysis of domestic wastewater can reveal the presence of illicit drugs either consumed by a population or directly discharged into the sewer system. In the search for causes of a recent malfunctioning of a small domestic wastewater treatment plant aberrantly high loads of amphetamine were observed in the influent of the plant. Direct discharges of chemical waste from illegal production sites were suspected to be the cause. Target analysis of drugs of abuse and non-target screening using high resolution mass spectrometry provided evidence of profiles of chemicals that can be used in tracking productions sites within the corresponding sewer catchment.

A model tool is presented that describes the chemistry in submerged rapid filtration, with focus on iron and manganese removal mechanisms. The model allows for varying parameter values referring to water influent quality, process conditions and model sorption and oxidation constants in order to investigate their influence on removal performance.
