The 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.

The filter-feeding Asian clam (Corbicula fluminea), an invasive species which entered Europe in the 1980s and was not recorded in Lake Constance until after 2000, has now colonized the eastern part of this lake. The extent of the invasion is shown by an ETH Zurich Environmental Sciences student’s Bachelor thesis, supervised at Eawag: densities of up to 900 clams per square metre were found in the lake.
