Although power plants have reduced sulfur dioxide emissions to the environment by 90%, European mountain rivers and streams will take decades to completely clean the acid. The Oxfordshire Hydrology Institute has analyzed the rivers of Wales, especially in times of flooding. Specifically, it has analyzed the transport of toxic chemicals. According to the report, although very harsh measures are taken on emissions, benefits would only be noted in the long run. Acid water accumulated in underground aquifers is constantly pumped into rivers and surface streams, so it would take decades for cleaning and cleaning.
