BANGINWARAbstract Water is a precious natural resource that needs to be protected and monitored otherwise it may be the vehicle for the spread of infectious diseases. In present study total 710 samples were analyzed, 355 each from open wells (Ows) and tube wells (TWs) of the different localities of Amravati City. Out of the total TW water samples, 81% were confirmed contaminated by MPN test, 74% by MFT and 10% content thermotolerant E.coli. Out of 355 OW water samples, 82°A) were confirmed contaminated by MPN test, 69% by MFT and 13% content thermotolerant E.coli. Analysis indicated that the maximum bacterial contamination was recorded during monsoon as compared to pre monsoon and post monsoon in OW. Thus, the present studies concluded that the contamination in the ground water were found generally due to secondary contaminant like discharge of sewage, faecal matter, percolation of industrial waste water etc., therefore, all such ground water sources should be protected from unhygienic sanitary condition to prevent bacterial contamination.and waterborne infections.
