Water is essential to sustain the life. Water samples have collected from a different urban area of H. D. Kote town of Mysore district from different sources such as hand pump, public taps, and stored household drinking water. Physico-chemical and microbiological characteristics of the water samples were analysed following the standard methods to evaluate the quality of drinking water. All physic-chemical parameters are within the permissible limit to WHO. The microbiological analysis shows that that t nearly 53 % of the samples were observed with coliform contamination. The significant difference among water sources regarding total plate count was observed, where stored household water has relatively higher compared to tap and borewell water exceeding the standard limit. Both hand pump and the tap water were not detected with any E. coli contamination whereas 80% of the household stored water samples have shown E. coli contamination. The presence of significant counts of coliforms in stored household water indicates post poor sanitation and existence of human activities. Attention should be given to the collection, storage, and management by additional treatment to maintain and prevent excessive microbial growth

MicroMedicine Journal , 2019
With the growing population and industrialization, the potability of drinking water has been decreased due to pollution and improper sanitization. In this context the present study was aimed to check the potability of drinking water by Multiple Tube method and Membrane Filter technique and to identify bacteria from Membrane Filter technique. 100 samples from 10 different wards of Belagavi City were collected. Bacteriological analysis was done for the presence of fecal coliforms, fecal Streptococci, Salmonella and Shigella by presumptive coliform test and multiple tube method (MPN) and membrane filter (MF) techniques were used for estimation of coliform bacteria. Twelve out of 100 samples were found to be unsatisfactory for drinking purpose. A total of five different strains were isolated from 100 samples. Genera isolated were Corynebacterium species, Micrococci, Gram positive Bacilli, Staphylococcus aureus, Citrobacter freundii. 88% of the sources were hygienic for drinking purposes and for the rest of the sources, proper measure should be taken to maintain sanitary of the drinking water by regular check on the equipment, maintaining structural faults and proper disinfection of equipments.

Background: In the current scenario, the urbanization is happening at a faster pace and the economy is not able to match at par with urbanization, this In turn is causing problems of unavailability of safe and potable water along with proper sewage system, despecially in urban slums. As a result of the scenario many urban slums are still using poor quality pit latrines and even drawing water from nearby wells, water taps which are not complying with government norms. Space is also a big problem which is being faced by these slums, due to which there is a lack of enough spaces in the houses and nearby areas, therby causing overcrowding. Due to overcrowding, the space between houses, pit latrines, wells, taps and water bodies has decreased and thus the potential of contamination of water bodies by fecal microorganisms has increased drastically. Given the above knowledge, a study is much needed to estimate the presumptive and differential coliform count of water samples from the urban slum area in Lucknow. Subjects & Methods: A cross-sectional survey was conducted during the period of January to June 2019. Samples were collected from all the taps, hand pumps that were currently in use, along with potable water stored in households of Sarvodaya Nagar (an urban slum area), Lucknow and were processed in the Microbiology department of IIMS&R, Lucknow. Results: A total of 53(63%) samples were taken from Public supply, out of which 36(67. 9%) were found unsatisfactory and 17(32.0%) were intermediate, were found to be contaminated with Pseudomonas sp., E.coli, Thermotolerent E.coli, Klebsiella Spp. Citrobacter, Enterococcus and Pseudornonas Spp., E.coli, Thermotolerent E.coli, Klebsiella respectively. In the study more than half of the samples were taken from the Public water supply. Out of these about seventy percent were unsatisfactory and were found to be contaminated with Pseudomonas. Conclusion: The proper sanitation, regular treatment, supervision of water sources, arid regular bacteriological assessment of all water sources for drinking should be planned and conducted.

A cross-sectional study was conducted to assess the bacteriological quality of water in Haldwani block, Nainital District, India. Stratified random sampling was used to categorize water sources and consumer points. In total, 108 samples were collected: 15 from the Gola river, 51 from water taps, 24 from water treatment plants and 18 from tube wells. Samples were tested for coliforms by the most probable number technique. Identification of species was done by standard procedures. Of 108 water samples, 58.8% were found to be polluted. All samples of water (n ¼ 15) from different sites of the Gola river were found to be highly contaminated. Out of 24 water treatment plant samples, four samples were found unsatisfactory, while more than half (51.6%) of its supplies to water taps were polluted. From tube wells and their water taps, 88.8 and 60% samples were found safe for drinking respectively. Bacterial contamination of water treatment plants and their supplies indicates significant disparities in the efficiency of water treatment processes. Contamination of water taps of tube wells suggests leakage of pipes. There is an urgent need to improve these services to ensure the supply of safe water for consumers.

Journal of entomology and zoology studies, 2018
A total of 112 water samples from Tawi river Pre-filtration, Post filtration water, household supplies, ponds and wells of kandi area and border belt in both summer and rainy season were collected and analysed for their microbial load. None of the samples complied with bacteriological standards for total Coliforms (TC), Faecal Coliforms (FC), Faecal Streptococcus (FS) and Clostridium perfringens (CP). During summer season, the values of TC, FC, FS, CP were highest (1359, 164, 664, 604 MPN/100ml respectively) in pre filtration Tawi river water and lowest (5.6, 3.5, 5.43 and 4.91 MPN/100ml respectively) in post filtration water. During rainy season also, the values of TC, FC, FS, CP were highest (2391, 227, 858 and 716 MPN/100ml respectively) in pre filtration Tawi river water and lowest (9.4, 6.2, 9.0 and 8.6 MPN/100ml respectively) in post filtration water. SPC/ml was highest for Tawi river (pre filtration) water (6.2×10 6) in rainy season and lowest for post filtration water (1.049×10 3) in summer season. Studies revealed cent percent faecal pollution of drinking water sources in the study area due to presence of coliform the indicator organisms. Highest level of faecal pollution was shown by Tawi River supplying inputs to the filtration plants. The water supply sources were unsatisfactory for drinking when compared with the WHO or BIS standards for coliform count. It was concluded that there is urgent need of public health advisory for public enlightenment by avoiding contaminated source of drinking water until corrective actions have been assured.
This study is a comparative analysis of physicochemical and bacteriological quality of drinking water intake in urban area of Patna District, Bihar state. A total of 68 drinking water samples randomly collected from 41 hand pumps, 14 municipal supply tap, 11 boring water and 2 well from 15 different locations of urban area of Patna District. Samples were collected aseptically in 60ml sterile plastic container for bacteriological and in 1 liter sterile plastic bottle for physicochemical parameter like pH, Total Hardness, Dissolved Oxygen, Biological Oxygen Demand, etc and compared with BIS (IS-10500). MPN test was applied to detect the presence of coliform in the drinking water samples. The total coliform count was detected in 57 out of 68 water samples. Most of the water samples were shown compromising physicochemical parameters. Total hardness (TH) is above the permissible limits detected in 60 out of 68 samples. Dissolved oxygen (D.O.) was also recorded below the standard for most of the samples .This results indicate that drinking water is highly in jeopardy to bacterial contamination. Construction of septic tanks near with boring and drinking water supply line short distance between water supply network and swage supply line poor constructed well head, cross contamination with waste water, Leakage in pipe line are the main cause of water contamination.

Bacteria in our drinking water are one of the main sources of waterborne diseases all over the world. Our study was aimed to investigate the extent of bacterial contamination in different drinking water sources (Tubewell, Dugwell, Municipal supply, Railway supply and River Ganga. The potable quality of drinking water was assessed from some of the villages of four blocks (Katihar, Manihari, Amdabad and Barari block) of Katihar district. The experiment was conducted during March 2013 to Feb 2015. Total bacterial density was recorded higher in river Ganga water (0.89×10L to 10.10×10L) followed by dugwell (0.56×10L to 2.62×10L), municipal supply(0.18×10L to 1.21×10L, tubewell (0.15×10Lto 1.96×10L)and railway supply water(0.04×10Lto 1.21×10L).Using MPN test the highest coliform count was (22 to 1612/100ml) inriver Ganga water and faecal coliform (00 to 395/100ml)in dugwell water. In the present investigation 13 bacterial species were identified. E. coli, S. faecalis, C. perfringens, P. v...
Bacteriological quality assessment of water supply schemes (WSS) of Mianwali, Punjab, Pakistan
Environmental Earth Sciences, 2019
This study investigated physico-chemical and bacteriological contamination in drinking water samples of Mianwali which involves assessment of 115 water supply schemes (WSS) along with determination of drinking water sources which have contributed significantly towards increasing bacteriological contamination (either ground or tap water source). For this purpose, one sample was collected from ground water; while, two samples were collected from tap water source of each scheme. Rapid Microbiological Testing Kit Method was used to test bacteriological contamination in drinking water samples. Results showed that 71% of the WSS were bacteriologically contaminated with fecal coliform bacteria, thus making overall water quality not suitable for drinking purposes. Water storage tanks used to supply water in 30% of WSS, have also contributed significantly (45%) in exceeding bacteriological contamination. Moreover, results showed that water quality obtained from tap water sources (71%) was more bacteriologically contaminated than ground water sources (41%) obtained from each WSS. Thus, WSS of Mianwali was not regarded safe because they are responsible for 30% bacteriological contamination in water samples. Hence, this study is just in time for the authorities to act immediately, as drinking water quality of Mianwali is gradually getting deteriorated.
Water is essential for the well being of mankind and for sustainable development. The provision of safe drinking water is one of the most effective and permanent technologies for improving the health of the people. People in several parts of India face an immense challenge to meet the basic needs of water. The crisis is not due to the lack of fresh water as such, but the availability of adequate quality water at the right place and time to meet basic needs. In this study, the presence of indicators of pollution, namely the faecal coliforms, total coliforms were used to detect the microbial quality of drinking water from various sources. The present study undertaken in the village of Sundaraperumal koil, near Kumbakonam, Tamilnadu, reveals that most of the drinking water sources are highly contaminated. The tap waters supplied by the local governing body is found to be much contaminated with coliforms and faecal coliforms when compared to the other water sources followed by the pond water, well water and river water.
