The changes of 17 parameters of water composition and water quality were determined by analytical methods described in Polish Standards. The quality of ground waters was estimated by comparing the results obtained with both limit values for drinking water in Poland and criteria of classification of ordinary ground waters according to Polish State Environmental Monitoring. It was found that ground water from each of the investigated water intake met all the requirements set for drinking water and household purposes (with few exceptions). The concentrations of most of the parameters determined within the research indicated waters of the highest (class la) and high quality (class lb). However, influence of anthropogenic factors was also marked on water purity. The limit value of the following parameters was occasionally exceeded: nitrate nitrogen - max. by 50% in Obrowiec and 20% in Chorula, sulphates - by 19% in Kamień Śląski, iron - by 100% in Górażdże.}, type={Article}, title={Estimation of the Quality of Ground Waters Provided for the Water-Supply System in the Area of Gogolin Commune}, URL={http://www.czasopisma.pan.pl/Content/124199/PDF-MASTER/9_AE_VOL_26_2_2000_Czerniawska_Estimation.pdf}, }
