DISINFECTION BYPRODUCTS IN DRINKING WATER FROM RURAL CENTRAL SYSTEM WATER SUPPLY
Abstract:
Identification of chlorination byproducts and their potential health hazards has created a major issue in balancing chemical toxicity with risks from pathogenic microbes. This paper evaluates rural central systems water supply established in the period 2006-2012 related to disinfection efficiency and the levels of disinfection by-products (trihalomethanes), correlated with other chemical/bacteriological parameters of the water. The results of our study emphasis that the quality of treated water has been in accordance to Romanian water law, only some of them having nitrates, ammonia and bacteria levels over CMA’s were residual free chlorine level below CMA’s. Disinfection by products levels in treated water samples were low, except by chloroform. A significant statistically correlation (p=0.05) was observed between the chloroform and residual chlorine level in the water.
