Abstract Inland waters are acidified from anthropogenic and from natural sources. The regional distribution and the degree of acidification depend on the pathways by which the acidifying elements - usually oxidized sulfur - are distributed. Acid rain and atmospheric deposition both affect soft water bodies in a long-term process. Geogenic acidification sources are more intense, but usually have restricted effective ranges. Geogenic sources originate from volcanoes, from acid sulfate soil drainage, and from acid mine drainages. The impacts of acidifying substances into inland waters change their characteristic chemical matrix, especially the dominating buffering systems which are usually based on aluminium and iron. The given degrees of acidification affect the aquatic biota both by acidity and toxic effects. Countermeasures against water acidification are possible both by source control and by treatment of the affected waters. Worldwide, there is a large body of experience about the different kinds of acidification and the suitability of treatment options.
