STUDY ON THE VALUE VARIATION OF SOME QUALITATIVE PARAMETERS OF DRINKING WATER

Abstract

The study presents the variations of the physical, chemical, microbiological and bacteriological parameters for water provided from two water resources intended for potabilisation, for use in domestic consumption and comparing the results with the legislation in force regarding the quality of drinking water. The two water resources intended for potabilisation are represented by the groundwater from the Capture of Crăciunesti (Tisa River) from Sighetu Marmaţiei and the second source of water is represented by the Firiza Dam, Baia Mare. For both water resources, the present paper presents the technological processes of treatment in order to obtain potable water, which is then distributed to the population through the drinking water distribution system. The study highlights the situation of the drinking water distribution system to the consumers in the 3 areas, the description of the catchments and the treatment technologies of the different water resources (surface water and groundwater) in order to fulfill the sanitary requirements for drinking water, as well as the results of the analyzes for the values of the physical, chemical, microbiological and bacteriological parameters obtained. The analysis of the results revealed value changes at the microbiological and bacteriological parameters only in the raw water, increased values of the turbidity in the raw water from the Firiza Dam, Baia Mare and increased values of the hardness parameter in the water from the underground resource from Sighetu Marmaţiei.
