The new European Drinking Water Directive (Legislative Regulation 18-2023) is Europe's response to climate change: a focus on sustainability that materializes in a shared commitment to the health and continuity of the water resource. The new regulation introduces changes to the parameters to be measured during periodic water analyses,” explains Antonio Acquafredda, Product Manager for Chemicals and Regulation at Culligan. “Climate change is the starting point for the development of the directive, which considers some of the elements that can pollute groundwater. An example is boron, which is the cause of the greater concentration of brackish water coming from the increasing infiltration of seawater into aquifers. Then, new new hazard parameters have been inserted, i.e. pollutants for which there is increasing attention to the effects on human health. These are waterproofing products (PFAS), which are carcinogenic, bisphenol A, microplastics, chlorites and chlorinated sanitation by-products and, as a precaution, uranium, whose presence is always linked to climate change. In addition, the controls will also be extended to structures such as apartments, which will have to be organized to monitor the water that reaches homes, with with special attention to Legionella and lead parameters.
