A series of organic and inorganic indicators have been analyzed in the drinking water from the respective locations. Out of the 37 samples collected in Ialomița county in 2016, the following indicators have exceeded the maximum admissible concentrations (MAC): sodium in 8% of the total samples, nitrogen in 38%, copper in 27%, manganese in 5%, iron, nickel and chromium in 3% of the samples. In Gorj County, samples from 25 locations were analyzed during 2017. Exceedings of MAC were recorded for hardness in 36% of the samples, for boron in 16%, for ammonium, iron and manganese in 12%, for sodium and for chloride in 4% of samples. In 2017 a total of 33 samples were analyzed in Tulcea County; the following indicators have exceeded MAC trihalomethanes and iron in 3% of samples and manganese and fluorides in 9% of samples. For the analyzed indicators that exceeded the maximum admissible concentrations a database including the physical-chemical characteristics of drinking water at the exit from the treatment plants was created.Admissible valuesDrinking waterPhysical-chemical indicators,Treatment plantsSymposium Proceedings
