Mineral waters in Brașov County. Characteristics and use

The sources of mineral water are spread all over Braşov County, but most of them have been identified and mapped in the central part of the county, namely at the contact between Transylvanian Depression with the western part of the Eastern Carpathians. Based on the analysis of the mineral water sources identified in the field during 2011 – 2016 period , three major types of mineral waters have been identified: chlorosodic, carbonated and hypothermal waters. Clorosodic waters are present within or close to areas of salt massives (the eastern and south-eastern edge of the Transylvanian Depression), some of these having high salty concentration (more than 70 g/l at Mercheaşa and Racoş). Carbonated mineral waters appear in the southern part of the neogen eruptive, respectively in the unit of the internal Carpathian flysch, on the Zizin-Tărlungeni-Săcele line. Hypothermal waters emerge on the Măieruş-Codlea line, having a constant temperature (23,4ºC at Măieruş and 18,4ºC at Codlea). Some locations with mineral water sources in the Brașov county used to be permanent or seasonal resorts of regional or local importance, many of them being currently abandoned or in an advanced degree of degradation (e.g. Băile Homorod, Băile Zizin, Băile Veneţia de Jos etc.), excepting Băile Rodbav and Băile Perşani which are still active
