River Ganges (locally called as river Ganga) is one of the most scared rivers in India. The symbol hope, faith and worshipped for its wholesomeness due to purity sanctity. Pollution water anthropogenic activity a very common issue worldwide. Similarly, Ganga pollution India throughout entire courses, major concern city outfalls. This river, also named Hooghly West Bengal, India, exposed outfall...

Fecal microbial pollution of recreational and shellfishing waters is a major human health and economic issue. Microbial pollution sourced from stormwater runoff is especially widespread, and strongly associated with urbanization. However, non-point source nutrient pollution is also problematic, and may come from sources different from fecal-derived pollution (i.e. fertilization of farm fields, ...

BACKGROUND The objective of this study was to evaluate the efficacy of Sanitization of Lettuce according to the protocols set forth by Iranian Ministry of Health and Medical Education for reducing populations of total coliform, fecal coliform, and helminth eggs present on lettuce. METHODS In the present study, we determined the load of total coliform, fecal coliform, and parasites of lettuce....

A rapid and sensitive method is described for the detection of bacteria in water and various other natural substrates by the isolation of specific bacteriophage. By the addition of large numbers of the organism in question to the sample, the presence of virulent bacteriophage can be demonstrated in as little as 6 to 8 h. Fecal coliform, total coliform, and total coliphage counts were determined...

The Honolulu Board of Water Supply (HBWS) selectively chlorinates half of its groundwater supply to provide drinking water that meets the Total Coliform Rule. The objective of this study was to determine whether the groundwater sources used by HBWS are vulnerable to contamination with fecal matter and would require routine disinfection. Larger volumes (1,000 mL) of samples from groundwater and ...

various physico chemical characteristics of the river ganga in varanasi were studied in the oct 2005 to nov 2006. ecological parameters like dissolved oxygen(do), ph, nitrate(no3-), po43- and bacterial population were analyzed and compared with standard permissible limits to assess the best designated use of the river water for various purposes. study revealed that the water quality at varanasi...

Colombo is a city surrounded by a large and interconnected system of natural wetlands. These wetlands which have historically provided a range of water services to the city are now believed to be threatened by degradation due to the recent changes in the urbanization patterns and urban lifestyle in Colombo. This paper presents a study on the current state and recent trends in surface water qual...

Predicting the presence of enteric viruses in surface waters is a complex modeling problem. Multiple water quality parameters that indicate the presence of human fecal material, the load of fecal material, and the amount of time fecal material has been in the environment are needed. This paper presents the results of a multiyear study of raw-water quality at the inlet of a potable-water plant t...

The inactivation of fecal coliforms in anaerobic batch reactors has been investigated at the thermophilic temperatures of 50, 55 and 60 °C. Throughout inactivation experiments at each temperature, individual colonies were isolated and identified by 16S rDNA gene sequencing to illustrate how the diversity of fecal coliforms is affected by thermophilic treatment. Results indicate that even though...
