Organic matter concentration in water of the karst zone dug wells

Abstract

The article presents the research data of the dug well water quality in the karst zone glacial lacustrine clay and moraine sandy loam in the four years (2004-2007).The amount of organic substances in the well water depended on fluctuation of the ground and the level of water. The largest amount of organic matters was established in the wells (6 and 7) which were in glacial lacustrine clays and in the shallowest well (4) of moraine sandy loams.The greatest amounts of organic substance were determined when the level of water fluctuated nearest the earth's surface (could get together with a surface flow) and nearest the ground of well (the amount of organic substances in the water has increased through ground deposits). Where the level of water fluctuated in the greatest amplitude, the least amounts of organic substance were determined.
