The springs in the Ojców National Park are one of the most important elements of the landscape. Despite their protection, they are exposed to pollution, mainly due to the increased tourism
and traffic in the Prądnik valley. Eleven physicochemical parameters for seven main springs have been
studied. The results were compared with the Polish regulations and with the previous studies to check the
rate of change of the spring water condition. The nutrient pollution turned out to be the most variable,
both in time and space.
