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

Hydrologica! data of salt water from Pestújhely 159 Temperature of the water at the outflow: 15.5 C°, that of the air at the same time: 19.0 C°. Specific gravity of the water: 1.00387 at 20 C°. Electric conductivity of the water kis = 0.007735 ohm1 cm"

1. Hydrogenion concentration = 7.7 pH. The above data show that the Pestújhely salt water belongs to the group of sodium chloride waters of small Li, Br, I and hydrocarbonate content and its composition is much similar to that of the salt water of Debrecen and Hajdúszoboszló. The further comparison shows, however, that the above one contains much less hydrocarbonate than the salt waters of the Great Hungarian Plain. Finally 1 can mention that newly another boring was located near to the above one (about 5 m from it) and the previously mentioned freshwater layer at the depth of 65 m is used for drinking purposes. This boring consists of 229 mm pipes and its yield equals 380 liters per minute. The chemical data of this water are according to the analysis of the State Institute for Public Health: Solid matter: 1772 mg/1. CI : 168.5 mg, NOs : 36 mg/1. Traces of nitrite, ammonia and sulfate. 19.3 German grades of hardness. The water of both pipes will be brought up by a pump station located in a shift made from concrete in a depth of about 12 m. During the digging of the shift many sea shells were found, also affirming the marine origin of the layers. On comparing the composition of the salt water of Pestújhely with some others known in Hungary we find that Water of Pestújhely contains 4.5 g/1 NaCl or 2.74 g/1 CI 0.0042 g/'l I. „ Rákospalota „ 6.9 „ 0.0059 „ „ Pesterzsébet „ 10.82 „ 0.0028 „ „ Dobó-well at Eger „ 1.77 „ 0.0112 „ „ Hajdúszoboszló, I. „ 3.15 „ 0.0084 „ II. „ 4.42 „ 2.70 0.0081 „ The world reknown bathing city of Budapest will much profit from the fact that from time to time new and new waters and springs of healing value will be discovered. We hope that a systematic hydrological examination of the near environment of Budapest will yet add to the value of the Hungarian metropolis. (From the State Institute of Chemistry, Budapest.
