ABSTRACT
In Poland about 40% of the population lives in a rural areas and despite of the great technical progress in the infrastructure, there are still areas without water supply system where portable water is drawn from the well. The subject of this work was to evaluate the quality of shallow well water (98–604 cm), which is a source of water for consumption. Studies covered 8 wells in the Gorzyce commune. The following chemical components: pH, dissolved oxygen, electrolytic conductivity, BOD5, nitrogen, total phosphorus and phosphates, and ions of SO4-, Na, K+, Ca++ and Mg++ were analyzed. The results of the studies are described by the mean concentrations of components in analyzed period of time. The results confirm the fact that, poorly protected wells have a worse quality of water. Moreover a few cases, the average concentration of the analyzed indexes exceed acceptable standards for drinking water.
