Aim of study: to evaluate microbiological quality of drinking water according Lithuanian drinking water standard HN 24:2003.
Material and methods. The data of microbiological tests of drinking water were collected from laboratories responsible of drinking water control in Kaunas region. Part of the study was carried out at Helsinki University (dep. of Food and Environmental Hygiene). Different microbiological criteria of drinking water samples from small community supply were examined.
Results. The results of our study showed that 94.4 % of drinking water from centralist drinking water supplies in Lithuania fulfill requirements of drinking water standard HN 24:2003 and is safe to drink.
Drinking water from dug wells more often are contaminated and does not fit drinking water standard requirements. We found that there were too much coliforms in 12,8 % of drinking water samples, enterococci in 23.4% and E. coli in 16.7 % respectively.
The study showed that there is a season variation of microbiological quality of drinking water. Less microbiological contamination of dinking water samples was during winter season from both water supply systems - centralist drinking water supplies and small community supplies.
Microbiological quality of drinking water in Lithuania from small community supplies was worse compare to drinking water from small community supplies in Finland. The average of E.coli bacteria in Lithuanian drinking water from small community supplies was 5.57±2,09/10... [to full text]
