  Contamination in drinking water is man made and usually due to improper handling, storage and serving which leads to the serious water borne diseases. A total of 340 drinking water samples were analyzed for bacterial contamination, out of them, 69.1% were non-potable by MPN method, 73.2% by MFT indicating presence of E. coli and 18.2% showed presence of thermotolerant E. coli of human fecal origin. Study concluded that poor hygiene behaviors such as improper method of storage, handling and serving, deteriorates the quality of drinking water which can be improved by imparting water hygiene behavior education to hotels and restaurants owners.

  Waterborne diseases are among the leading causes of morbidity and mortality in developing countries and every year around 2.2 million people die due to basic hygiene related diseases like coliform diarrhoea. The total 1000 sample from various sources such as tube wells (340), open wells (340) and hotels and restaurants (320) were analyzed for the presence of Escherichia coli contamination in drinking water and recorded 425 water samples contaminated with total coliform by MPN technique. Out of them 85 strains of thermotolerant Escherichia coli 51 (60%) from open well, 23 (32%) from tube well and 11 (13%) from hotels and restaurants were isolated and identified. These isolates showed maximum resistance to ofloxacin followed by novobiocin, cefdinir and ciprofloxacin. The azithromycin; gentamycin, amikacin, chloramphenicol, co-trimoxazole and tetracycline were the most effective while the ofloxacin, novobiocin, cefdinir and ciprofloxacin were the least effective against the E. coli isolated strains. Thus findings recommended that amikacin and azithromycin, gentamicin, chloramphenicol and tetracyclin are the best choice of drugs, while the ofloxacin, cefdinir, ciprofloxacin and novobiocin antibiotics should be avoided against E. coli diarrhoeal infections in the region.

  Total 225 drinking water samples from hotels and restaurants in Amravati city were analyzed by standard MPN technique for determination of bacteriological quality and hygiene behaviors on quality deterioration of water. Out of these, 143 (63.5%) were non-potable and 82 (36.4%) potable by MPN test. Out of these 143 non-potable water samples, 86 (60.1%) were confirmed faecal contaminated by Eijkman test. Study showed that highest contamination recorded in roadside hotels and dhaba`s (83.3%). The 83.3% contamination was recorded in drinking water stored in containers without tap and 100% where drinking water withdrawn directly by dipping hands or utensil without handle. The hygiene behaviors such as the frequency of washing of storage container, hygienic condition of hotels/ restaurants owners and workers, uniform of worker, number of customer per day, health education of workers and owners also affect the potability of drinking water in hotel and restaurants.
