Epidemiologic evidence on the relation between contaminants in drinking water and cancer is reviewed. The reviewed studies cover exposure to: disinfection byproducts; nitrate; arsenic and other metals; volatiles and contaminants from hazardous waste sites; asbestiform fibers; radionuclides; and fluoride....
In this study, we have used WaterCAD software to design and to analyze the proposed water distribution network of Bhogpur gram panchayat of Panskura 2 block of Purba Medinipur District in West Bengal. The analytic study is based on a surface water-based pipeline water delivery scheme, ...
More than one billion people around the world do not have clean drinking water.Their water supplies are unsafe because of natural or man-made pollution,such as industrial chemicals or human and animal wastes.Also water-related diseases(与水有关的病菌)kill millions of people each year,mostly chil...
(lat. 30�_S., altitude 1000 m), measurements of water intake and water expenditure of grazing, lactating Merino ewes from which drinking water had been withheld for 22 months were compared with those of ewes with water supplied, in order to produce a table of water balance for each ...
Customer complaints concerning taste and odor are a continuing concern of the water supply industry because they are associated with poor drinking water quality by consumers. Many tastes and odors are caused by low concentration levels of organic compounds. Some of these compounds are naturally occurri...
Women's participation in programmes for drinking water supply and sanitation in developing countries The first part of this document considers the traditional involvement of women in the maintenance and management of water supply.

The candidature of Fe−Si and Mg−Al alloys at millimeter-scale particle sizes for chemical degradation of disinfection byproducts (DBPs) in drinking water systems was substantiated by their enhanced corrosion resistance and catalytic effect on the degradation. The Mg−Al particles supplied electro...
Tests were performed using a laboratory-based filtration unit, with dual filter media configurations and synthetic raw water. The glass media showed comparable performance for both filtration and backwashing and avoided the breakthrough of particles in the effluent. Moreover, the promising performance ...
Controlled, pilot-plant ozone treatment tests were conducted on twenty-nine volatile organic contaminants in distilled water and groundwater. Results show that aromatic compounds and alkenes are well removed by ozone treatment, but that alkanes are poorly removed. Also, efficiency of destruction improved...
The results suggest that the source of methionine does not influence its metabolic effect. Thus, it seems that methionine from the water is as good as when supplied wholly from the feed.doi:10.4081/ijas.2012.e46CadirciSahinPAGEPress PublicationsItalian Journal of Animal Science...
