Vitális Sándor dr.: Salgótarján megyei város vízellátása

482 Dr. Sándor Vitális b) The test boring located north-eastly of the city at the Miner Colony Inászó in the neighourhood of the old shaft Ferenc lies at a height of 313.766 meters above sea level. The boring has beaten from 0 to 10.00 m Pleistocenic, from 10.00 to 96.56 m Lower Miocenic (Aquitanien) coal cover layers and coal formations, then crossed from 96.56 to 146.18 m Lower Miocenic (Aquitanien) coal bed formation and reached the water holding glauconitic sand-sandstone layers at 146.18—326.90 m depth. The level of this water holding layer lies in undisturbed state at —39.62 m depth, i. e. 274.146 m above sea level. This boring had a water yield of 105 liters in each minute at a depression of 70 meters. The ob\ained water was an alkaline water containing sodium bicarbonate, available, however, for potable purposes. c) Two further test borings located southwards of Salgótarján at Kisterenye have also beaten the water holding gravel bed and glauconitic sandstone layers. The water obtained of these borings was of significant amounts. The quality of the water was, however, objectionable as potable water owing to its high content on sodium bicarbonate. This high content would perhaps make its evaluation as mineral water possible. The results of the borings prove that the water obtained of the gravel bed, respectively of the glauconitic sandstone can only be used as potable water on such spots where no thick layers of rhiolitic tuff lie above them. The high content on sodium bicarbonate is naturally caused by these tuffs. d) The boring located at Zagyvapálfalva at the plant of the glass factory lies at a height of 218.546 m above sea level. This boring had beaten the water holding layer of glauconitic sand-sandstone below the Holocenic sediment at a depth of 8.40—101.10 meters. The water level of the well is in undisturbed state at —1.40 m, i. e. at 217.146 m above sea level. The yield of the well is 300 liters in each minute at a depression of 48 meters. e) The test boring located at the railway station at Salgótarján is under work. Down to a depth of 70 m it has beaten glauconitic sandstone containing water. As the above mentioned data of borings show, the layers of glauconitic sand-sandstone are good water holding strata. The accumulating water can be obtained and utilised by means of deep borings located at adapted spots. Places adapted for test borings and water storage are: Kis Gedőc Puszta, the valley of the rivulet at Salgó and the environment of the Market Place.
