Weltweit beziehen 300 Millionen Menschen ihr Wasser aus Grundwasservorräten, die stark mit Arsen oder Fluorid belastet sind.
April 28, 2016

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.

What is required to facilitate the adoption of new technologies such as potable water reuse? According to a study carried out by environmental social scientists in California, users need to see not only how an innovation benefits them personally, but also that it is compatible the community’s values and can become a routine part of daily life.
