Geogenic contamination of drinking water is a global problem that affects hundreds of millions of people worldwide, but research is taking place on ways to find solutions to this debilitating health problem. Today, Eawag’s Water Resource Quality team has released the Geogenic Contamination Handbook, which will help government agencies, NGOs, planning agencies and engineers, decision makers and water resource managers to identify contaminated regions and mitigate the debilitating health problems caused by the effects of arsenic and fluoride contamination.
