The first studies of carbonated mineral waters in the vicinity of Bakhchisarai in Crimea in 1916-1917 were conducted by Academician V. A. Obruchev and hydrogeologist of the Tauride Zemstvo Peddakas. Unfortunately, these works were not completed, and V. A. Obruchev's article "The Burun-Kaya Mineral Spring Near Bakhchisarai as a Future "Crimean Resort"" was ignored. Meanwhile, Academician V. A. Obruchev was the first to establish carbonated mineral waters in Crimea. According to his data, the said mineral spring is confined to tectonic cracks of north-eastern extension, intersecting the Upper Cretaceous white marls. Referring the reader to the article, we will cite from it some of the most important data for our topic. V. A. Obruchev writes that the Burun-Kaya spring does not dry up even in the driest years, "... when he helped out the entire surrounding population" with water, because other nearby sources, fed by groundwater, dried up.
