Drinking Water

Prevention is better than cure

Thanks to the fact that Switzerland’s surface waters have been kept clean, this maxim has to a large extent been upheld. However, the presence of new (harmful) substances allows no room for complacency on this front. Globally, there is an urgent need for cost-effective and energy-efficient water treatment solutions on various scales - all the way through to wastewater recycling.

What is the contribution of upstream areas to micropollutant loads in the Rhine at Basel and Düsseldorf? How effectively do authorities and water suppliers collaborate on management and regulation across national boundaries? An interdisciplinary approach developed by Eawag scientists can help to identify deficiencies. Read more

Faced with polluted river water, rural communities or aid agencies often drill groundwater wells to obtain water supplies. But data collected systematically for the first time in the Amazon basin show that this “solution” can create new problems: the groundwater may contain elevated concentrations of arsenic, manganese and aluminium – up to 70 times over the recommended limit in the case of arsenic, and up to 15 times for manganese.
