Probabilistic analysis of risks to U.S. drinking water intakes from 1,4‐dioxane in domestic wastewater treatment plant effluents
The risks of 1,4‐dioxane (dioxane) concentrations in wastewater treatment plant (WWTP) effluents, receiving primarily domestic wastewater, to downstream drinking water intakes was estimated using distributions of measured dioxane concentrations in effluents from 40 WWTPs and surface water dilution factors of 1,323 drinking water intakes across the U.S. Effluent samples were spiked with an ...

A survey of the characteristics and maintenance of rainwater tanks in urban areas of South Australia
Households resident in metropolitan Adelaide and surrounding areas in South Australia were recruited into a randomised controlled trial. A total of 630 rainwater tanks with a total tank capacity of 14.5 ML were installed at the 325 households surveyed. The majority of the tanks were plumbed into the kitchen (64.6%), over 10 years in age (45.5%), over 15,000 L in capacity (42.5%) and composed of ...

Effects of improved storage containers on the bacteriological quality of household drinking water in low-income urban communities in Ibadan, Nigeria
This study assessed the effectiveness of improved storage containers on household drinking water quality in four low-income urban communities in Ibadan, Nigeria. Three hundred randomly selected respondents were interviewed, while 44 households were selected and randomly assigned to four improved container treatment groups: Covered Buckets with Taps (CBT), Covered Buckets without Taps (CB), ...

Determinants of household participation in the management of rural water supply systems: A case from Ethiopia
Access to safe drinking water supply in Ethiopia is among the lowest in sub-Saharan Africa. While both governmental and non-governmental organizations have implemented water supply projects in recent years, many fail shortly after construction due to improper management. In this paper, we examine socio-economic, institutional and exogenous factors affecting household participation in the ...

Away-from-home drinking water consumption practices and the microbiological quality of water consumed in rural western Kenya
A cross-sectional descriptive study was conducted to examine away-from-home drinking water consumption practices and the microbiological quality of water consumed in rural western Kenya. The study involved adults and schoolchildren. Data were collected using focus group discussions, questionnaire survey, observations, diaries and interviews. The findings suggest that away-from-home drinking water ...

Access to safe drinking water and human health: empirical evidence from rural Bhutan
Provision of safe drinking water is essential for the promotion of human well-being. This paper makes an attempt to examine the patterns of access to drinking water, identify and analyze the factors that influence households access to safe drinking water sources, and analyze factors determining the extent of households travel to fetch drinking water, and assess the effects of access to safe ...

Myths about PVC
I hear myths about PVC all the time. I have been in the industry for just over 20 years and have run across many different polymers, but none as flexible and diverse in use as PVC -- otherwise known as polyvinyl chloride. PVC was first discovered in the 1800’s, and then rediscovered and patented in 1913 by a German inventor Friedrich Heinrich August Klatt. BF Goodrich then worked on ...

The effects of input materials on ceramic water filter efficacy for household drinking water treatment
Locally manufactured ceramic filters can improve drinking water quality and reduce diarrheal disease burden in developing countries; however, production methods and quality control protocols vary at the >50 factories. We manufactured filter disks with varied clay, burn-out material, burn-out material sieved with different mesh sizes, and burn-out material to clay ratios and calculated ...

Missing the Millennium Development Goal targets for water and sanitation in urban areas
"This paper reviews progress towards the Millennium Development Goals (MDGs) for water and sanitation in urban areas. Drawing on UN data, it shows the disastrous performance of many low- and middle-income nations in relation to the goal of halving the proportion without drinking water sources piped on premises and improved sanitation between 1990 and 2015. It also describes how even such a poor ...

Biofilm formation on materials commonly used in household drinking water systems
Biofilms are surface-associated bacterial communities that predominate in natural and pathogenic ecosystems. Their formation in drinking water systems creates potential risks for consumers’ health. Herein we tested biofilm formation on materials commonly used for indoor household drinking water systems (copper, PVC and stainless steel) simulating an average family water usage. Water parameters ...
