MICROBIOLOGICAL ANALYSIS OF WATER FROM SHALLOW WELLS

Analiza voda je temelj brige o ljudima i živim organizmima. U vodi žive brojni mikroorganizmi koji mogu biti opasni za zdravlje čovjeka. Kako je voda najvažnija tvar na planeti za život, važno ju je očuvati. Pitke vode na svijetu je vrlo malo, a i taj mali postotak je često zagađen i nije zdravstveno ispravan za korištenje. Voda se analizira na nekoliko načina, a jedan od najbitnijih je mikrobiološka analiza. Ona se provodila na uzorcima vode iz plitkih bunara na području Virovitičko-podravske županije. Voda se analizirala najpouzdanijom metodom mikrobiološke analize, a to je membranska filtracija kojom se bakterije nacjepljuju na hranjivu podlogu i uzgajaju. Time se uzgoje bakterije prisutne u vodi, a gdje neke od njih mogu biti veoma opasne za zdravlje ljudi. Analizom je pokazano kako većina voda iz plitkih bunara ne zadovoljava mikrobiološke uvjete te time može ugroziti zdravlje čovjeka. Većina bakterija u pitkoj vodi su koliformne bakterije, a čijom analizom su ustanovljene brojne kolonije tih vrsta bakterija. Water analysis is the foundation of concern for people and living organisms. There are numerous microorganisms that can be dangerous to human health. As water is the most important substance on the planet for life, it is important to preserve it. Drinking water in the world is very small, and this small percentage is often polluted and is not healthy for use. Water is analyzed in several ways, and one of the most important is microbiological analysis. It was conducted on samples of water from shallow wells in the area of Virovitica-Podravina County. Water was analyzed by the most reliable method of microbiological analysis, which is the membrane filtration by which the bacteria are drawn to the nutrient base and grown. This raises the bacteria present in the water, and where some of them can be very dangerous to human health. The analysis shows that most of the water from shallow wells does not meet microbiological conditions and can thus endanger human health. Most bacteria in drinking water are coliform bacteria, and by this analysis numerous colonies of these bacterial species have been found.
