PREVENTIVNE MJERE POBOLJŠANJA ZDRAVSTVENE ISPRAVNOSTI VODE IZ INDIVIDUALNIH VODOOPSKRBNIH OBJEKATA NA PODRUČJIMA RAZORENIM RATOM

MIROSLAV VENUS

Svrha rada bila je provjera uspješnosti provedbe sanacije, inače neprikladanih bunara, na područjima razorenim ratom. Ukupno je sanirano 198 bunara s područja općine Voćin, i to hiperkloriranjem i ispumpavanjem vode, nakon čega je provedena dezinfekcija klornim preparatom. Uzorci vode uzeti za bakteriološku analizu analizirani su na ukupne koliformne bakterije, fekalne koliformne bakterije i fekalne streptokoke, koji su obrađivani metodom membranske filtracije, dok je broj kolonija aerobnih bakterija na 37°C i 22°C određivan u triptoza-glukoza-kvasac agaru. Ispravnih uzoraka s obzirom na Pravilnik o zdravstvenoj ispravnosti vode za piće bilo je 152, odnosno 77%. U neispravnim uzorcima, kojih je bilo 46 ili 23% najčešće su izolirani fekalni streptokoki s učestalošću od 30%. Iako je javni vodovod najbolji način opskrbe stanovništva kvalitetnom pitkom vodom, moguće je postići zadovoljavajući stupanj kvalitete pitke vode iz bunara provedbom javnozdravstvenih aktivnosti, ako se provode periodički i stručno.

Summary. 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 Vo}in, 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°C and 37°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 periodi- cally and professionally.
