In these days, it is scarcely possible to bathe safely in lakes, streams and rivers because of the steadily increasing contamination of surface waters with waste and sewage. In addition, technological demands also put a strain on our „aquatic landscape“. This entirely revised CD provides useful examples and deals with the resulting perils, as well as with general questions regarding contamination and purification of bodies of open water. The meaning of the analytical controls applied is discussed, together with wastewater purification methods, nature-tailored development of water bodies and lake rehabilitation measures.
