Artesian Water in the Vicinity of Černá Hora (Black Hill)
In 1958 a hydrogeological investigation was carried out south of Černá Hora in the distnct of Blansko. The purpose of this investigation was to provide sufficient quantities of drinking water for the local water supply. The village lies at the confines of two expressive geomorphological and geological wholes, the Boskovice Furrow and the Brno Eruptive Mass which meet here on an expressive fault dislocation. At first, the hydrogeologists were concerned with sediments of Miocene age deposited along the dividing line of the above two wholes, in expressive valley depressions of tectonic origin and composed predominantly of noncohesive sediments. As a result of boring, 3 horizons of subterranean water were ascertained in the place called "U zeleného kříže" (At the Green Cross). The lowest-situated horizon has an artesian confined water surface. After the cutting off of the upper two horizons, pumping proved that the volume of the artesian confined water made 13,33 L per second at a lowering of the surface by 11,7 m. The water has favourable physical, chemical as well as bacteriological qualities. The investigation did not, however, substantiate the common belief that in the past the river Svitava flew through this region towards the South. From the geomorphology of the area under investigation we may deduce that the depression between Černá Hora and Závist is of tectonic origin. Since the geological conditions keep on repeating also in other places along the dividing line between the Boskovice Furrow and the Brno Eruptive Mass, we may presume that hydrogeological conditions of Miocene sediments - deposited in tectonic depressions or elsewhere - are favourable.
