Leiguarda, Peso, and Kempny (1948) reported that no Shigella were isolated during their river water studies in Argentina, although 67 per cent of the samples showed Salmonella. Gispen and Gan (1950) also reported the frequent isolation of Salmonella from river water in Indonesia, but Shigella were not recovered. During a five-year study of irrigation water in Colorado, the present authors likew...

The data on the occurrence of keratinolytic fungi in sewage, municipal solid waste and waste-contaminated habitats are reviewed. In these habitats, keratinolytic fungi occur with extreme abundance. The factors influencing qualitative and quantitative compositions of the fungi in the habitats are discussed. It is concluded that keratinolytic fungi can be the bioindicators of environmental pollut...

In this paper we employ a stated preference environmental valuation technique, namely the choice experiment method, to estimate local public's willingness to pay (WTP) for improvements in the capacity and technology of a sewage treatment plant (STP) in Chandernagore municipality, located on the banks of the River Ganga in India. A pilot choice experiment study is administered to 150 randomly se...

Urban rivers are polluted with discharge from sewage treatment plants and overflowing sewage caused by rainfall (Nix and Merry, 1990; Shiraris et al., 1987). These waste waters accelerate eutrophication of aquatic environments. Since urban river water is the public water supply source, it is an i~0ortant for public health issue to determine whether or not urban rivers are polluted with fecal ef...
