On the basis of this long tradition even in the present Czech Drinking Water Standard, microbiological (=bacteriological) criteria, based upon the laboratory cultivation technique, and biological (=hydrobiological) criteria, based predominantly upon direct microscopic examinations of water samples. The occurrence of undesirable aquatic organisms in distribution systems of drinking water, causing aesthetic, technological and hygienic problems, is a well-known phenomenon. With the increasing drinking water demand more eutrophicated surface water resources have been utilized for drinking water processing, often without the adequate separation of plankton biomass. Other problems are solved in surface waters, mainly presence and characterization of periphyton. Specification of biological study, co-operation with other areas (chemistry, technology, etc.). Study of organisms, specification and characterization of cell (eucaryotic and procaryotic), non-cells organisms (viruses), taxonomy. Detailed specifications of organisms - alga, cyanobacteria, protozoans, metazoans (determinations). Types and sorts of waters (surface, underground, standing and flowing) from the biological point of view, biocenosis of organisms (adaptations).Eutrophication, water blooms, cyanotoxins, problems of open air pools. Biological problems of industrial cooling circuits and air-conditioning systems, waste waters and so on. Methods of cultivations and specific indicators of water quality.
