ABSTRACT: Water of Quaternary sediments of the Trenčianska kotlina valley is typical fluviogenic water recharged by precipitation, by infiltrated surface water and by water transfered from aadjacent geological units. Ground water chemical composition is formed by basic processes - dissolving of carbonatic components of sandy gravel deposits and dissolution of silicate mineraIs. Important influence has also the anthropogenic contamination, which is the source of chlorides, sulfates, nitrates, oil products and another organic pollutants. Ground water is of ten not suitable for drinking purposses (Standard STN 75 7111 - Drinking water) due to low content of oxygen and high content of iron, manganesse, amonium, nitrates and organic pollutants. High quality water occurs in right side terasse of river Váh in Chocholná village and in marginal part of the area, where water of high quality transfers from the Mesozoic carbonate complexes.
