Water intended for human consumption - Part I: Compliance with European water quality standards

Among the European Union Directives enacted on water management and environmental protection, Directive98/83/EC defines the mandatory quality standards for water intended for human consumption in order to protect humanhealth. The implementation of this Directive has often encountered delays due to the following: the exact mechanismsfor monitoring and enforcement have not yet been fully identified, several EU countries had set more stringent drinkingwater standards while others needed to update their national regulation, financial resources to comply with the directivewere not always available, and the recent enlargement of the EU has raised fiu'ther issues. In this study an evaluationof the regulations on drinking water in European and Mediterranean countries was carried out. The attention focusedon Directive 98/83/EC and to its implementation in the Member States, also considering the recent (2004) EU enlargement,which brought ten new countries into the European Union. Finally, a comparison among the new standards ondisinfection by-products (DBPs) adopted by the different countries is presented along with the USEPA approach toDBPs control.
