Characterization of mineral springs from the Buila Vanturarita natural park area

Abstract

This study present the results of the physico-chemical, microbiological and hydrochemical characterization obtained for the mineral water samples taken from 14 mineral springs located in the Buila-Vinturarita National Park area. For this study, has been conducted three sampling campaigns, in November 2017, March 2018 and June 2018, for each mineral spring. The physico-chemical quality indicators analyzed for each source were: pH, chlorides, sulfates, bicarbonates, sodium, potassium, calcium, magnesium, total silica and sulfides and hydrogen sulfide. In parallel with the physico-chemical indicators, microbiological indicators were also determined, namely: total number of bacteria at 22˚C, total number of bacteria at 37˚C, total coliform bacteria, Escherichia coli, enterococci and Pseudomona aeruginosa. The results of the physico-chemical and microbiological analyzes obtained for the studied mineral springs were compared with the provisions of the Romanian legislation in force GD 1020/2005, which transposes into the national legislation the European Directive 2009/54 / EC. Also in the present study, along with the physico-chemical and microbiological characterization of the mineral water samples, studies were carried out on the hydrochemical characterization of these springs. These hydrochemical characterization studies were done by plotting the "Piper Diagrams". With the help of the Piper Diagrams, we could have a more detailed view of the mineral springs studied, from the analytical point of view and from the point of view of the typology of these springs.
