Karst areas are among the world’s most vulnerable landscapes to environmental impacts. Most of pollution in karst areas is due to unsustainable anthropogenic activities (intensive agriculture and industry, unregulated urbanization) that are reflected in the decline of subterranean biodiversity and in the loss of drinking water resources. The comparison of pollution in two analyzed springs (Dobličica and Jelševnik/Jezero) in 1987 vs. 2014 revealed a concerning growing trend for both nitrates and orthophosphates.
