In view of various studies looking for the merit of coliphages as indicators of water pollution with viruses originating from faecal material, a small agricultural community (population of approximately 1500 inhabitants of all ages, 2-3 km from Haifa) was selected in order to understand these bacteriophage ecology (F-RNA and somatic coliphages) in its sewer and oxidation pond system. Along the ...

MSC is announcing a new business offering based upon a breakthrough technology. MSC has developed a means by which design engineers or occasional CAE software users can reliably perform complex engineering analysis with the same resultant quality as do the dedicated analysis experts. This breakthrough technology captures the expert’s engineering knowledge and specific process solution methodolo...

As part of the revised EU Bathing Water Directive, there is scope to discount bathing water quality samples which show poor water quality if poor water quality is predicted and the public forewarned. The Cloud to Coast (C2C) project is developing a model to allow prediction of faecal indicator organism (FIO) concentrations in bathing waters. One of the C2C sub-models is investigating FIO loads ...

On-site sanitation is the main form of excreta disposal in most sub-Saharan African cities and will remain the most appropriate level of service for the urban poor in the medium term. Despite heavy public investment in sewerage systems in most primary and some secondary cities, typically only 10-15% of the urban population benefit from access to the sewer network. About 80% of the urban populat...

Gregory S. Burge, Department of Economics, University of Oklahoma Abstract Development impact fees are a controversial method of financing local public infrastructure. While their effects on home values have been examined extensively, very few studies have investigated how they influence the price of undeveloped land. A 16 year panel is used to investigate the effects of impact fee programs in ...

The environmental issues associated with residual colour in textile efnuents have posed a major challenge to environmental scientists as well as the textile colouration processors. The requirements to remove colour from textile efnuent on si te prior to discharge to sewer have been progressively tightened due to increased public complaints about coloured watercourses. Dyes are highly dispersibl...

The mercury (Hg) content of dental-operatory wastewater has become an issue in many localities, and Hg removal is rapidly becoming a matter of concern for all dental clinics. This preliminary study tested the efficacy of polymers for the removal of Hg contaminants from the dental-unit wastewater stream. Two commercially available polymers were used to treat dental-operatory wastewater. Used sep...

Recent research suggests future alterations in rainfall patterns due to climate variability, affecting public safety and health in urban areas. Urban growth, one of the main drivers of change in the current century, will also affect these conditions. Traditional drainage approaches using grey infrastructure offer low adaptation to an uncertain future. New methodologies of stormwater management ...
