Law 14/1986 of 25 April, General of Health, established the obligation of public health administrations to direct their actions as a priority to the promotion of health and the prevention of diseases.

The Law provides that activities and products which, directly or indirectly, may have negative consequences for health, are subject to control by public administrations and to carry out health measures for the improvement of water supply systems.

The Royal Decree 1138/1990 of 14 September, for which the Technical-Health Regulations for the supply and quality control of drinking water for public consumption are approved, incorporated into our legal system Community Directive 80 /778/EEC of 15 July 1980.

The publication of Directive 98 /83/EC of 3 November 1998 requires the incorporation of the same into Spanish national law with the drafting of a new text containing the new scientific and scientific specifications. The Commission has been able to provide a framework for the development of the European Community's economic and social policy in the context of the European Community, with the support of the European Parliament and the Council of the European Union. the protection of the health of consumers, this being the main object of this provision.

Given the importance of this topic for human health, it is necessary to establish at national level criteria for the quality of water for human consumption.

These criteria shall apply to all waters which, irrespective of their origin and the treatment of their potential, are used in the food industry or supplied via distribution networks. public or private, deposits or tanks.

Parameters and parametric values are set to be met at the point where human consumption water is made available to the consumer. These values are based mainly on the recommendations of the World Health Organization and on public health grounds, in some cases applying the precautionary principle to ensure a high level of protection of health population.

Water quality control programmes for human consumption should be adapted to the needs of each supply and meet the quality criteria provided for in this provision.

The substances used in the treatment of water purification and construction products installed in the supply and in the interior installations can affect the quality and health of the water, and without prejudice to the provisions of this rule, shall be governed by specific rules.

In the face of non-compliance with the quality criteria indicated by this provision, the underlying cause will be investigated and the corrective and preventive measures for protection will be implemented as soon as possible. of the health of the population supplied. Derogations may be granted under certain conditions, where the supply of water in supply cannot be maintained by any other reasonable means, provided that there is no potential risk to the health of the population.

Decisions on monitoring the quality of water for human consumption, as well as the adoption of corrective measures in the face of detected non-compliance, will be implemented at the local level, in accordance with the powers conferred on them. local authorities in Law 7/1985 of 2 April, Regulating the Bases of the Local Regime, following, where appropriate, the indications of the competent autonomic health administration and counting on their advice.

Consumers should receive sufficient and timely information about the quality of water for human consumption, situations of exception, corrective and preventive measures, as well as all aspects affecting the supply of water. and which may involve a risk to the health of the population.

The Ministry of Health and Consumer Affairs coordinates the National Consumer Water Information System and prepares annual national reports for public information and, in compliance with Community obligations, to the European Commission.

This Royal Decree, which is of a basic standard, is dictated by the provisions of Article 149.1.16.^a of the Constitution and in accordance with the provisions of Articles 18.6, 19.2, 23, 24, 40.2, 40.13 and in the second provision of Law 14/1986, of 25 April, General of Health.

Notes:

(1) For accuracy, systematic error is understood and represents the difference between the mean value of the large number of repeated measurements and the exact value. (*)

(2) The random error is precisely understood and is usually expressed as the standard deviation (within each batch and between batches) of the dispersion of results around the mean. Double the relative standard deviation is considered to be acceptable. (*)

(*) These terms are defined in greater detail in ISO 5725.

(3) The limit of detection is:

Either triple the relative standard deviation within the batch of a natural sample containing a low concentration of the parameter, or the quintuple of the relative standard deviation within the batch of a blank sample.

(4) The method should determine the total cyanide in all its forms from 1 January 2004.

(5) The characteristics specified for the results apply to each of the specified substances at 25 per 100 of the parametric value in Annex I.

(6) Oxidation shall be carried out for 10 minutes at boiling in acidity, using permanganate.

(7) The characteristics specified for the results apply to each of the pesticides and will depend on the pesticide in question.

(8) The characteristics specified for the results apply to each of the substances specified at 50 per 100 of the parametric value in Annex I.

(9) Although it is not possible, at the moment, to meet the limit of detection for some pesticide and aromatic polycyclic hydrocarbon, laboratories should try to comply with this standard.

2. With regard to hydrogen ion concentration, the characteristics specified for the results assume that the test method applied can measure concentrations equal to the value of the parameter with an accuracy of 0,2 units pH and one accuracy of 0.2 pH units.

C. Parameters for which no test method is specified: total organic carbon, residual free chlorine, combined residual chlorine, reductive sulphite clostridium, colour, cryptosporidium, microcytine, odour and taste.
