Study of microbiological analysis of drinking water during monsoon season from selected area of Garhwa (Jharkhand).

摘要

Present paper represents the analytical picture of potable water contamination with microbiological agents. It lays emphasis on access of poor quality of drinking water by the people from different sources like bore well, public well and public fountain due to complete absence of infrastructure for supply of safe drinking water as per guidelines suggested by WHO. Presence of coli form bacteria was detected in 15 out of 25 samples collected from different localities of densely populated area and Salmonella paratyphi B, Pseudomonas putrifaciens, Streptococcus faecaelis, Shigella spp. and Escherichia coli as well as protozoa, Acanthoamoeba were isolated which are pathogen of several type of serious diseases like gastroenteritis, typhoid fever and hepatitis. The most probable number (MPN) show all sample contains microorganism beyond permissible level varying from 7 to 170 100-1 mL.
