Abstract

Drinking water must be sanogenic and clean, so water treatment is essential for the health of the human body. Drinking water must be free of microorganisms, parasites or substances which by number or concentration may constitute a potential hazard to human health. Water quality monitoring is important because in the absence of drinking conditions, water can cause serious damage and can be a way of transmitting different toxic chemicals to the body. Water quality assessment depends on the quality of the results obtained in the control program. The quality of the results depends entirely on the accuracy of the analysis method, the quality control being fundamental to the success of the monitoring program. Quality indicators that need to be investigated in water in the distribution network are: microbiological indicators, free residual chlorine, turbidity, physico-chemical indicators and indirect indicators of organic pollution such as: CCO-Mn, ammonium, nitrites, nitrates. Health expertise of drinking water will also be mandatory in the following situations: choosing new sources, when laboratory tests indicate a risk to the health of consumers, in case of suspected illness of aquatic origin, whenever there is a significant change or an event that can affect water quality (floods, building new targets). In the present paper is presented relevant aspects regarding monitoring the quality of drinking water and as well as a case study on monitoring the quality of drinking water distributed in the city of Rovinari in Gorj county.
