Abstract:

Quality water must be health providing, clean, devoided of microorganisms, parasites or substances. Homeowners with private water supplies may be exposed unknowingly to health related pollutants unless they voluntarily have their water tested for the correct water quality parameters, especially in water environmental situation.The present paper emphasizes that water microbiologically polluted, is a potential hazard for human and animal health. Due to heavy rains in 2006, in village Galda de Jos, from Alba County, 28 households were flooded. In a first stage, decontamination of water wells was achieved. After 4 days from water decontamination enteritis cases occurred in hens and cattle, except for pigs. Starting from the symptoms and the beginning of the problems, experimental studies were centred upon following in time the microbiological growth of water. Following the results of tests carried out (bacteria growing at 37C - mesophilic, coliform bacteria, E. coli and enterococci) a new decontamination was initiated that leaded to the disappearance of diarrhea cases.


Keywords: water wells, flood, pollution, colony-forming unit, coliform bacteria, E. Coli, Enterococcus
