Geological journal| Резюме: | The article discusses changes in the indices of qualitative composition (mineralization and sulphates) of groundwater intakes within Lviv region during exploitation. It has been established that these changes have significantly different character depending on lithology of water-bearing and above lying rocks. The main reasons for the deterioration of groundwater quality in the operation of water intake are geochemical changes in technogenic aeration zone, in particular sulfuric acid leaching process. Аs a result of these changes groundwaters in limestone and marl, which are of high natural sulfur content, and increasingly exposed to natural leaching factors, are the most vulnerable. |
