Description: Evaluation modern methods of drinking water quality were analyzed. The results of experimental investigations of water properties, that based on the samples of gas-discharge emission images in a pulse electromagnetic field were submitted. The methods of bringing the image to the standard background brightness had been proposed. The database of database of gasdischarge emission images was formed. . The water classification system, that based on calculation of the Euclidean distance between the medians of the pixels number in the brightness sub-bands was developed.
