Agriculture has the most significant influence on the worsening of underground water quality. Use of fertilizers, manure and crop protection chemicals has led to underground water pollution. Engine fuels and lubricates, petroleum contamination and industrial waste from industrial air and water pollution are all threats of water contamination. During the period of forty years after the second world war there was an increase in of fertilizer use (by more than a hundred times) and in pesticide use (by more than thirty times). The application of both in agriculture has led to a double negative result, mainly: health problems and soil exhaustion. It was proved that the death rate due to cancer and poisonings among rural men is 10% higher in the country than in the towns. Consumption of water which is contaminated with a great number of biogenic compounds, can bring about such health problems as: skin, eyes, digestive system, respiratory problems and osseous systems diseases. Especially water with high a nitrates content can cause methemoglobinemia and also activate hypertension. Underground waters in the Opole region are being researched within the monitoring system. These waters are differently isolated from the ground surface. It has been observed that even deep waters are endangered by pollution, which causes their quality degradation. Water quality is characterised by a high concentration of nitrates and nitrites and occasionally by a fluorides and nickel content. Furthermore, a high concentration of sulphates, calcium, phosphates and hydrogen carbonates has been found. (fragment of text)
