[Preventive measures for improvement of suitability of water from individual water supply objects in the areas ravaged by war].

The aim of this article was to test the success of sanation of unsatisfactory individual water supply objects in the areas ravages of war. 198 individual water supply objects were consolidated in the area of Voćin, with hyperchlorination and pumping out of water, after which desinfection with chlorine preparation was carried out. Samples of drinking water taken for bacteriological analysis were analyzed on total coliform bacteria, fecal coliform bacteria and fecal streptococci by method of membranous filtration, while the number of colonies of aerobic bacteria at 22 degrees C and 37 degrees C were determined on triptosis-glucosis-yeast agar. Good samples, considering the Regulations on health suitability of drinking water, were 152, or 77%. In unfit samples, which were 46, or 23%, the most common isolates were fecal streptococci, with frequency of 30%. Although public waterworks represent the best way to supply people with good drinking water, it is possible to achieve a satisfactory degree of water quality from individual water supply objects with implementation of public health activities, if we execute them periodically and professionally.
