S. S. de Finály: Hydrological data of a salt water from Pestújhely

Hydrological data of a salt water from Pestújhely. By Chern. Eng. S. S. de Findly. The „Vass József" hospital of the Országos Társadalombiztosító Intézet located at Pestújhely wanted freshwater for drinking and bathing purposes. The directors asked Prof. Dr. Aladár Vendl as a geological expert to locate the place for a boring. The actual boring was made by the firm Leféber és Társa under the control of Engineer Péter Lengyel to whom the author is much indebted for the technical data of the boring. The boring was began with a 305 mm pipe which reached a depth of 70 m then pipes with a diameter of 203 mm followed. To exclude the water of the surface layers, another covering pipe of 500 mm diameter was applied within the first 18 m depth and the place between the pipes was filled up with concrete. Horizons yielding freshwater were found in the depths of 65m, then at 90 m and 150 m, until finally a salt water layer was beaten at 180 m depth. This water could, however, not reach the surface. Its amount reached about 270 liters per minute under a depression of 5—6 m by means of a compressorpump. Some earth gas also came up with the water but its quantity was verylittle against the air amount of the compressor so I could not affirm its presence. 1 am told, however, that later on the earth gas could be burnt for minutes. From a hydrological point of view also other salt water occurrences near to Budapest will be interesting. In the year 1912 salt water and earth gas broke out from sandy gravel in a depth of 230 m at Vicziántelep near to Örszentmiklós.

1 No further data of this eruption are stated in the literature. In the same year also at Rákospalota salt water and erumping earth gas of a depth of 183 m was found but the quality of the products was not examined further.- Another salt water occurrence at Örszentmiklós is stated where — at a boring after freshwater — salt water broke out of an excavated marl of a depth 400 m.
