WASTEWATER TREATMENT PLANTS (WWTPs): Blue indicates WWTPs compliant with the requirements of the Directive 91/271/EEC (UWWTD). Red indicates WWTPs that are not compliant with the UWWTD, either because they do not collect a sufficient number of samples per year or because the effluent is not within the limits set by the UWWTD.
