Reclaimed wastewater has become a potential water resource for many dry areas. Its recovery should be regarded as an additional stage in the water cycle providing a new water resource and preserving other high quality sources for more demanding applications. However, in this new scenario, a special attention should be paid to its physicochemical and microbiological quality to avoid damage to pu...

Treatment of domestic wastewater, at both the village and urban level, remains a problem in most developing countries. This is a review paper illustrating the use of duckweed-based wastewater treatment systems that provide genuine solutions to these problems. They are inexpensive to install as well as to operate and maintain. They do not require expensive technologies. Therefore, this review pa...

The species Escherichia coli comprises different subgroups with distinct phylogeny, physiology and ecology and, thus, presumably, with different roles in antimicrobial resistance dissemination. E. coli strains isolated from raw and treated municipal wastewater and from urban water streams were characterized in terms of phylogenetic groups, antimicrobial resistance patterns and the presence of c...

Victoria Harbour has received substantial loadings of pollutants from industrial and municipal wastewater discharged since the 1950s. Inputs of contaminants have declined dramatically during the last two decades as a result of better controls at the source and improved wastewater treatment facilities. To assess the spatial and temporal changes of metal contaminants in sediments in Victoria Harb...

Urban development and increased impervious surfaces have contributed to pollution loading in the Chattahoochee River and Proctor Creek, major urban waterways and receiving waters for Atlanta stormwater and wastewater effluent. The purpose of this study was to investigate spatial and temporal variation in E. coli and bacteriophage MS2 and relationships with Dissolved Oxygen, turbidity, rainfall,...

this study was conducted to investigate the characteristics of input and output wastewater of the bandargaz wastewater treatment plant on the basis of the data collected during operation and the samples taken during the study period. for this purpose, three samples were taken from the outflow wastewater and 25 quality parameters were tested. also, four soil samples were taken from the soils whi...

To better characterize Cryptosporidium in the Potomac River watershed, a PCR-based genotyping tool was used to analyze 64 base flow and 28 storm flow samples from five sites in the watershed. These sites included two water treatment plant intakes, as well as three upstream sites, each associated with a different type of land use. The uses, including urban wastewater, agricultural (cattle) waste...

Water and wastewater treatment and conveyance account for approximately 4% of US electric consumption, with 80% used for conveyance. Net zero water (NZW) buildings would alleviate demands for a portion of this energy, for water, and for the treatment of drinking water for pesticides and toxic chemical releases in source water. However, domestic wastewater contains nitrogen loads much greater th...

EPA Method 1600 and Enterolert are used interchangeably to measure Enterococcus for fecal contamination of public beaches, but the methods occasionally produce different results. Here we assess whether these differences are attributable to the selectivity for certain species within the Enterococcus group. Both methods were used to obtain 1279 isolates from 17 environmental samples, including in...

This study was done to assess the risk of helminth infection in association with wastewater-fed rice cultivation in an agricultural setting of Nam Dinh city, Vietnam. In a cross sectional survey data were collected for 202 households in a commune where wastewater was used for irrigation and for 201 households in a commune that used river water. Parasitological examination was conducted on singl...
