Directive 2009/54/EC of the European Parliament and of the CouncilShow full title

II. REQUIREMENTS AND CRITERIA FOR APPLYING THE DEFINITION

1.1. Requirements for geological and hydrological surveys

There shall be a requirement to supply the following particulars:

1.1.1.

the exact site of the catchment with indication of its altitude, on a map with a scale of not more than 1:1 000;

1.1.2.

a detailed geological report on the origin and nature of the terrain;

1.1.3.

the stratigraphy of the hydrogeological layer;

1.1.4.

a description of the catchment operations;

1.1.5.

the demarcation of the area or details of other measures protecting the spring against pollution.

1.2. Requirements for physical, chemical and physico-chemical surveys

These surveys shall establish:

1.2.1.

the rate of flow of the spring;

1.2.2.

the temperature of the water at source and the ambient temperature;

1.2.3.

the relationship between the nature of the terrain and the nature and type of minerals in the water;

1.2.4.

the dry residues at 180 °C and 260 °C;

1.2.5.

the electrical conductivity or resistivity, with the measurement temperature having to be specified;

1.2.6.

the hydrogen ion concentration (pH);

1.2.7.

the anions and cations;

1.2.8.

the non-ionised elements;

1.2.9.

the trace elements;

1.2.10.

the radio-actinological properties at source;

1.2.11.

where appropriate, the relative isotope levels of the constituent elements of water, oxygen (¹⁶O — ¹⁸O) and hydrogen (protium, deuterium, tritium);

1.2.12.

the toxicity of certain constituent elements of the water, taking account of the limits laid down for each of them.

1.3. Criteria for microbiological analyses at source

These analyses shall include:

1.3.1.

a demonstration of the absence of parasites and pathogenic micro-organisms;

1.3.2.

a quantitative determination of the revivable colony count indicative of faecal contamination:

(a)

absence of Escherichia coli and other coliforms in 250 ml at 37 °C and 44,5 °C;

(b)

absence of faecal streptococci in 250 ml;

(c)

absence of sporulated sulphite-reducing anaerobes in 50 ml;

(d)

absence of Pseudomonas aeruginosa in 250 ml;

1.3.3.

determination of the revivable total colony count per ml of water:

(a)

at 20 to 22 °C in 72 hours on agar-agar or an agar-gelatine mixture;

(b)

at 37 °C in 24 hours on agar-agar.

1.4. Requirements for clinical and pharmacological analyses

1.4.1. The analyses, which shall be carried out in accordance with scientifically recognised methods, shall be suited to the particular characteristics of the natural mineral water and its effects on the human organism, such as diuresis, gastric and intestinal functions, compensation for mineral deficiencies.

1.4.2. The establishment of the consistency and concordance of a substantial number of clinical observations may, if appropriate, take the place of the analyses referred to in point 1.4.1. Clinical analyses may, in appropriate cases, take the place of the analyses referred to in point 1.4.1 provided that the consistency and concordance of a substantial number of observations enable the same results to be obtained.
