Conditions for the preparation, transport and distribution of bacteriophage reference materials and preservation of samples had been defined. A method based on flocculation with Mg(OH2) with concentration efficiencies from about 40% was settled to concentrate phages from bathing waters. All methods were successfully implemented in routine laboratories all around the EU. Data on the occurrence of bacteriophages as compared to E. coli and Enterococci are available from diverse situations encountered in the EU. Results allow to conclude that the potential of phages for the determination of the microbiological quality of bathing waters merits to be considered since their determination is feasible and their behaviour in natural water differs from the behaviour of bacterial indicators and consequently they add valuable information
