<abstract xmlns="http://www.w3.org/1999/xhtml">The aggressive properties of natural waters arise due to their specific physical properties and chemical composition. The latest analyses of certified natural and healing mineral water sources according to Act No. 538/2005 were used for the evaluation. A total of 53 sources in 26 localities were evaluated; they comprised 25 sources of bottled natural mineral and healing waters and 28 sources of natural healing waters in 9 spas. The aggressiveness of the water against concrete was weak (17 sources), medium (17 sources), or none (19 sources). The aggressiveness was mostly caused by low pH values and/or increased SO42− content. Their corrosiveness to metal was mostly very high. The results showed that the disintegration of concrete building constructions, well casings and pipelines could occur in most of the evaluated localities in the case of mineral water contacting them. Therefore, preventive measures are necessary.</abstract>
