May 31, 2016In the future, water requirements for global crop production could be reduced as a result of climate change. This is the conclusion of a study by an international research team which included Eawag scientists.

May 25, 2016Biofilms are complex communities of microorganisms such as bacteria or algae. In aquatic ecosystems, they serve essential functions, e.g. as a food resource. They also play an important role in wastewater treatment and in biofuel production.

May 23, 2016A unique research and innovation platform has opened its doors: on 23 May 2016, the modular experimental building NEST was inaugurated on the Dübendorf campus of the two research institutes Empa and Eawag.

May 20, 2016Ageing infrastructure, global population growth and increasing urbanization call for new approaches in the water supply and wastewater management sector.

May 9, 2016No two bacteria are identical – even when they are genetically the same. A new study reveals the conditions under which bacteria become individualists and how they help their colony grow when times get tough.

April 28, 2016The interactive and free available Groundwater Assessment Platform (GAP) is now online. Over 300 million people worldwide use groundwater contaminated with arsenic or fluoride as a source of drinking water. Researchers in the Department of Water Resources & Drinking Water have developed a method whereby the risk of contamination in a given area can be estimated using geological, topographical and other environmental data without having to test samples from every single groundwater resource.

April 28, 2016In the modular experimental building known as NEST, Eawag and Empa – together with industrial and scientific partners – are investigating new forms of living and working, innovative construction methods and energy-efficient technologies.

April 21, 2016In the last century, the natural reproduction of whitefish and Arctic char in several Swiss lakes was adversely affected by high levels of nutrient inputs. So far, stocking measures have been implemented in efforts to support fish populations and maintain yields. The effectiveness of these measures varies according to the particular species and lake.

April 13, 2016The pipe material used for shower hoses or tap connections influences the type and amount of bacterial growth. This was shown by an Eawag study in which the microbiological impact of six commonly used plastic pipe materials was compared in a shower simulator over an eight-month period.
