This paper employs the discrete choice experiment method to estimate the benefits of improved wastewater treatment programs to mitigate the impacts of water pollution in Nairobi, Kenya. Urban and peri-urban farmers who use wastewater for irrigation from Motoine to Ngong River in Nairobi were randomly selected for the study. A random parameter logit model was used to estimate the individual leve...

This can create si...

To the Editor: A nationwide outbreak of cholera caused by Vibrio cholerae O1 serotype Ogawa began in Haiti in October 2010 and has since resulted in >200,000 illnesses and 4,000 deaths (1). Additional cases of cholera attributed to the outbreak strain have subsequently been reported in the neighboring Dominican Republic and in Florida and New Jersey in the United States. In these instances, ill...

The need for treatment of dilute metal contaminated water as a residual from mining and mineral processing facilities is ubiquitous. Electrochemical technologies have the potential to provide selective and measurable recovery of base metals from dilute mining influenced water. However, the technology is currently not widely used in the treatment of mining influenced water (MIW). The principles ...

Widespread contamination of arsenic in Bangladesh has been jeopardizing the health of millions of people. Residents of Matlab, Bangladesh, are among the millions at risk. Using bivariate models in the analysis of survey data, knowledge of health risks and avoidance of arsenic exposure in response to widespread contamination of arsenic for residents of Matlab were estimated. The models examined ...

thechah nimeh reservoirs of sistan is as one of the main water sources of zabol city used for drinking, agriculture, industry and livestock purposes. this study aimed to determine the contribution of the natural and concentration factors of heavy metals such as cd, pb and cu in sediment of chah nimeh of sistan. the concentrations of heavy metals in surface sediments were studied in six stations...

background: in the current study,the hazard quotient, the hazard index (hi) and spatial variations of fe,mn,cu and cr in drinking water sources of andimesk-shush, khuzestan province, southern iranaquifer were assessed. methods: we compared theconcentrations of aforementioned heavy metals in wells and springs inandimeshk and shush regions. the non-carcinogenic risk assessment of heavy metals was...

INTRODUCTION: Textile industry (and especially its part focused on the dyeing process) belongs among important sources of contamination responsible for the continuous pollution of the environment. The production of textile industry, as well as the volume of waste water containing processed textile dyes, steadily increases. The release of dyes into the environment constitutes only a small propor...

In the context of water resource management and pollution control, the characterization of water quality impairments and identification of dominant pollutants are of critical importance. In this study, water quality impairment was assessed on the basis of 7 hydrochemical variables that were monitored bimonthly at 17 sites in 2010 along the rural-suburban-urban portion of the Wen-Rui Tang River ...
