Water supply of the City Salgótarján 481 1. The water of the Hotocenic inundation sediment gravel. The water stored within the inundation sediment gravel bed can always be found on the flood area of the rivulet Tarján and its branch valleys. This water is, however, defiled in the internal territory of the thickly habitated city. This water storing bed has rich accumulations of non-defiled water outside of the city, in the direction against Somoskőújfalu, Vízválasztó and Kisterenye. This available water could be used by locating wells of low depths (5—10 meters). The drawback of such waters is, however, their high hardness and the possibility of defilements. This water accumulation should be investigated in the valley of the rivulet at Salgó and of the rivulet Tarján (in the direction of Somosk'őujfalu) by means of 1—2 testing bores since this is the cheapest method of water supply in case the quality of water proves to be available. 2. The water of the lower Miocenic ( Aquitanien ) sand bed and gravel. The public well at the Fő-tér, the well of the Mining Authority, etc. take their water out of the gravel bed. This gravel could be opened by wells within the rivulet at Salgó outside the Plant of the Steel Factory. Two cross dips form a structural bed in the city between the Catholic Church and the Chief Station. Beyond these dips the glauconitic sandstone lies on the surface. The water of the gravel and sand bed can be made available in this bed in a depth of 80—150 meters by adapted borings. The best place for such borings in the city would be the Market Place and its surroundings. 3. The water of the Upper Oligocenic (Cattien) glauconitic sandstone. The glauconitic sand and sandstone can be found on a vast area on the surface in the city of Salgótarján and its environments. The test borings located in this sandstone proved its good water accumulating capacity. a) The test boring No. X. located northly of the city at Kis Gedőc puszta lies at a height of 276.118 meters above sea level. This boring has beaten the glauconitic sandstone below the Holocenic sediment in a depth from 12.50 to 100.00 meters. The boring yields in each minute 20 liter water. At a depression of 4—5 meters in each minute 120 liter, at a depression of 11.5—16.25 meters in each minute 128—180 liter water could be obtained. The quality of the water was good. The water basin in the environment of Kis Gedőc puszta is larger than 10 sq. km, thus the water accumulating layers are supplied annually by about 1,400.000 cu. m. precipitate water.
