 Hello there my name is Manuela and we will discuss the removal of pesticide metabolites now from drinking water with a special focus on DMS in Denmark. In Denmark we have a drinking water production that is based on groundwater and pesticides were detected in 51% of our abstraction wells and DMS in 35% of them. We only have a very simple water treatment train based on aeration and rapid sand filtration, and that's why we have problems removing those pesticide metabolites as it's simply not designed for it. We also have a very low parametric value for DMS and our authorities are very cautious about implementing new technologies. And that's why we require a lot of research to get this allowance. And my PhD project is trying to provide this knowledge and investigates the DMS removal efficiency, as well as evaluate some technologies according to selected parameters. Let's jump right into some of the results we have so far. We start with granular activated carbon. We did an absorption isotherm experiment and a full scale documentation of the breakthrough together with the breakthrough model. The outcome, well, we found out that yes, DMS can be removed by activated carbon, but only at very low KD values, and that means that it's very expensive to clean DMS from drinking water with activated carbon compared to other metabolites. What about the next technology, advanced oxidation with a medium pressure UV lamp and hydrogen parasite. Well, we had a setup with and without biologically activated carbon filters as post treatment. And yes, again the outcome DMS can be removed, but it requires more energy compared to other metabolites. And we also detected some byproducts of which we so far only have documented nitrite to be removed by the back treatment afterwards. So we have to check if we come below the parametric value with the other byproducts. And we also found some non target analysis compounds, which we have to check if there's health risks related with those 12 transformation products after the back filtration. And this was it from my side so far. And thank you for your attention. And I really hope you come visit me at my poster so that we can discuss a bit more about pesticide metabolite removal from drinking water. Thank you for your attention.
