COUNCIL DIRECTIVE of 8 December 1975 concerning the Quality of Bathing Water
THE COUNCIL OF THE EUROPEAN COMMUNITIES,
Having regard to the Treaty establishing the European Economic Community, and in particular Articles 100 and 235 thereof,
Having regard to the proposal from the Commission,
Having regard to the opinion of the European Parliament (1),
Having regard to the opinion of the Economic and Social Committee (2),
Whereas, in order to protect the environment and public health, it is necessary to reduce the pollution of bathing water and to protect such water against further deterioration;
Whereas surveillance of bathing water is necessary in order to attain, within the framework of the operation of the common market, the Community's objectives as regards the improvement of living conditions, the harmonious development of economic activities throughout the Community and continuous and balanced expansion;
Whereas there exist in this area certain laws, regulations or administrative provisions in Member States which directly affect the functioning of the common market; whereas however, not all the powers needed to act in this way have been provided for in the Treaty;
Whereas the program of action of the European Communities on the environment (3) provides that quality objectives are to be jointly drawn up fixing the various requirements which an environment must meet inter alia the definition of parameters for water, including bathing water;
Whereas, in order to attain these quality objectives, the Member States must lay down limit values corresponding to certain parameters; whereas bathing water must be made to conform to these values within 10 years following the notification of this Directive;
Whereas it should be provided that bathing water will, under certain conditions, be deemed to conform to the relevant parametric values even if a certain percentage of samples taken during the bathing season does not comply with the limits specified in the Annex;
Whereas, to achieve a certain degree of flexibility in the application of this Directive, the Member States must have the power to provide for derogations; whereas such derogations must not, however, disregard requirements essential for the protection of public health;
Whereas technical progress necessitates rapid adaptation of the technical requirements laid down in the Annex; whereas, in order to facilitate the introduction of the measures required for this purpose, a procedure should be provided for whereby close cooperation would be established between the Member States and the Commission within a Committee on Adaptation to Technical Progress;
Whereas public interest in the environment and in the improvement of its quality is increasing; whereas the public should therefore receive objective information on the quality of bathing water,
HAS ADOPTED THIS DIRECTIVE:
Article 1
- bathing is explicitly authorized by the competent authorities of each Member State, or
- bathing is not prohibited and is traditionally practised by a large number of bathers;
(b)'bathing area' means any place where bathing water is found;
(c)'bathing season' means the period during which a large number of bathers can be expected, in the light of local custom, and any local rules which may exist concerning bathing and weather conditions.
Article 2
The physical, chemical and microbiological parameters applicable to bathing water are indicated in the Annex which forms an integral part of this Directive.
Article 3
This Directive may be waived:
(a) in the case of certain parameters marked (0) in the Annex, because of exceptional weather or geographical conditions;
(b)when bathing water undergoes natural enrichment in certain substances causing a deviation from the values prescribed in the Annex.
Natural enrichment means the process whereby, without human intervention, a given body of water receives from the soil certain substances contained therein. In no case may the exceptions provided for in this Article disregard the requirements essential for public health protection.
Where a Member State waives the provisions of this Directive, it shall forthwith notify the Commission thereof, stating its reasons and the periods anticipated.
Article 9
Such amendments as are necessary for adapting this Directive to technical progress shall relate to:
- the methods of analysis
- the G and I parameter values set out in the Annex.
They shall be adopted in accordance with the procedure laid down in Article 11.
Article 10
Member States shall, four years following the notification of this Directive and at regular intervals thereafter, submit a comprehensive report to the Commission on their bathing water and the most significant characteristics thereof.
After prior consent has been obtained from the Member State concerned the Commission may publish the information obtained.
Article 14
This Directive is addressed to the Member States. Done at Brussels, 8 December 1975.
