The "puzzle" of the standard for drinking water
The general philosophy adopted by the World Health Organization, the United States and Canada in establishing the standards of contaminants in drinking water is based on toxicological data. The criteria for the protection of man's health are based on the organoleptic, toxic and carcinogenic properties of contaminants. In most member countries the guideline numbers laid down in EEC Directive 80/778 are not taken into consideration. The microbiological parameters are adopted in every country except for parameter 62 and 61. New parameters to be considered are residual ClO(2), residual ozone, chlorite, chlorate, corrosivity index, NTA and EDTA. Parameters which require more precise definition/ specification are conductivity, suspended solids, mineral oils, oxidisability, surface-active agents and cobalt.
