Abstract. Drinking water is an essential element in the assurance of public health and the quality of life. Today the sources of drinking water as rivers, lakes and underground waters are in danger of being polluted by different contaminants. Water’s quality can be defined as a conventional assemble of physical, chemical biological and bacteriological characteristics, expressed as a value which allows the evaluation of the sample and the appreciation of its category. In the European legislation, as well as in our national legislation permitted levels for contaminants in drinking water Maximum are described. The concentration level domain varies from a zero in case of microorganisms such as Coloformii faecali to very small values–like ng/L for other contaminants–all these limits are established concerning the potential danger for human health or the modification of the quality organoleptic characteristics of the water.
