European countries follow different procedures to monitor the quality of the water of swimming pools open to the public: some use generally accepted technical standards, some officially recommended guidelines, some rules or regulations by local authorities and some have national laws or regulations. These agree insofar as in every country the water of swimming pools must be disinfected. The microbiological limits are to a certain extent identical with drinking water threshold values, e.g., no faecal coliforms must be present in 100 ml. Other microorganisms as for instance legionellae, staphylococci or Pseudomonas aeruginosa ar not uniformly considered. In all countries the water must be disinfected by chlorination. Big differences exist, however, in respect of the maximum admissible concentrations of free or total chlorine, haloforms and organic carbons. With regard to the common goals, harmonization of the regulations appears possible.
