For a safe and sustainable drinking water supply, the quality of drinking water as well as raw waters must be continuously monitored using increasingly complex water analyses. In this completely revised edition, adapted to the current drinking water regulations, Walter Kölle provides a comprehensive overview of the fundamentals of water chemistry, the relevance of various measurement parameters for different water types, the occurrence of natural and anthropogenic water constituents, as well as practical tips for calculating and evaluating analytical data, based on numerous example analyses. The limit values valid in Germany and the EU according to the Drinking Water Ordinance and the European Drinking Water Directive are consistently taken into account. Numerous parameters have been newly included, such as pharmaceuticals and construction chemicals.
