Fecal contamination and organic pollution of an agricultural drainage in northeast Indiana was high. Bacterial counts (total coliform, TC; fecal coliform, FC; and fecal streptococcus, FS) and biochemical oxygen demand (BOD) were used to assess waste concentrations. Coliform counts indicated that sections of the drainage receiving septic effluent had waste concentrations far in excess of public ...

With a view to evaluating a small-scale water disinfection system based on production and application of oxidizing gases, the level of equivalent residual chlorine and the degree of contamination by fecal and total coliform bacteria was assessed at various points in the drinking water system of a Mexico City hospital before and after installation of the disinfection equipment. Tests done in May...

A study on the distribution patterns of enteropathogenic bacteria polluting the shoreline in Natal, Rio Grande do Norte, Brazil, was carried out based on 72 samples obtained from three storm sewers and adjoining beach locations, Praia do Meio (PM), Areia Preta (AP) and Ponta Negra (PN). From each location, 12 water samples were taken and analyzed for fecal coliforms (FC) and Escherichia coli. I...

Rainwater harvesting is currently practiced widely in several countries worldwide on scales that vary according to rainwater availability as a mean of providing on-site supply of fresh water for isolated areas or those lacking proper water supply system. Different factors affect the quality of harvested rainwater mainly the multi-components of the collection system installed. In order to breakd...

Fecal coliform bacteria are widely used as indicators of sewage contamination in surface water. However, there are some disadvantages in these microbial techniques including time consuming (18-48h) and inability in discriminating between human and animal fecal material sources. Therefore, it is necessary to seek a more specific indicator of human sanitary waste. In this study, the feasibility w...

Coliforms (FB) posing population health risks in groundwater (GW) have been identified for decades, with recent studies assessing how hydrogeological and non-hydrogeological parameters correlate their presence. This study focused on explaining the physicochemical hydrological factors influencing presence of fecal contamination GW system Ad-Dawadmi, KSA, a hyperarid area facing prolonged drought...

Increasing pressure on water resources in the world has revealed necessity of using marginal irrigation. With use wastewater, which is one resources, freshwater alleviated, discharge problems wastewater are solved, and soil crop productivity increase with high nutritive effect wastewater. However, salinity, heavy metals, some harmful chemicals, pathogen risks should not be ignored. In this cont...
