Drinking Water

Laboratories play an important role in effective water quality monitoring. The Eawag department of Sanitation, Water and Solid Waste for Development (Sandec) is collaborating on the REACHLabs project, which is analysing the effectiveness of fit-for-purpose (FFP) laboratories in rural areas of low- and middle-income countries. FFP labs are laboratories designed to meet specific local operational and management needs of rural water supplies.

Researchers at Eawag have complied and analysed a globally unique data set on the occurrence of various amphipods in groundwater. They were able to show that land use within a radius of up to one kilometre from the groundwater extraction site has an impact on these sensitive creatures. This could indicate that the current groundwater protection zones are not large enough.

Researchers at ETH Zurich have developed a new way to break down a dangerous subgroup of PFAS known as PFOS. With the help of nanoparticles and ultrasound, piezocatalysis could offer an effective alternative to existing processes in the future.

Cities need to become more sustainable and use their water resources more efficiently. Managing water in small-scale cycles is one possible solution. A new white paper shows how this can be achieved.
