Spanish institute charts levels of trihalomethanes in drinking water • Water News Europe

New research analyses the presence of trihalomethanes in tap water in 26 European countries. Trihalomethanes are formed unintendedly as a by-product when chlorine is used to disinfect drinking water. According to the large-scale study led by the Barcelona Institute for Global Health (ISGlobal) more than 6.500 cases of bladder cancer—nearly 5% of all cases in Europe— can be attributed to exposure to trihalomethanes (THMs) in drinking water.

IS Global analysed in their  study  that was published on the 15th of January recent data on trihalomethanes levels in European municipal tap water.
