# Directive 2009/54/EC of the European Parliament and of the Council of 18 June 2009 on the exploitation and marketing of natural mineral waters (Recast) (Text with EEA relevance), Division 1.2: Requirements for physical, chemical and physico-chemical surveys

Extent: E+W+S+N.I.

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.
