Microbiological assessment of private drinking water supplies in Co. Cork, Ireland
The microbiological quality of 75 private drinking water supply boreholes in Co. Cork, Ireland was assessed in order to determine the incidence of contamination and the potential pathways of such contamination. Microbiological analysis was carried out using the membrane filtration technique for the recovery of thermotolerant (faecal) coliforms. The sanitary protection of the supplies was ...

Economic impacts of inadequate sanitation in Bangladesh
This study estimates the nonmonetary, financial, and economic costs of poor sanitation in the areas of health, drinking water, and domestic water, as well as user preference and welfare. Financial costs refer to the direct financial expense paid in monetary terms by someone, such as changes in household and government spending and real income losses for households. Nonmonetary costs consist of ...

Possibilities for reuse of treated domestic wastewater in The Netherlands
The implementation of wastewater reuse is becoming an increasingly important means of supplementing water supply needs and/or reducing costs. The present paper provides examples of possible uses of treated domestic effluent for the three sectors, i.e. public water supply, industrial and agricultural uses with the aim to address the feasibility of these applications. It is concluded that, although ...

Assessment of personal hygiene and sanitation using a composite index among adolescent girls and their households in urban slums of Pune, Maharashtra
The assessment of hygiene and sanitation in urban slums is essential to identify adolescent health needs. A tool that comprised of three domains and 13 variables including drinking water index (DWI), personal hygiene index (PHI) and household hygiene index (HHI) was developed and tested among 60 households. Observations were repeated after 6 weeks. Cronbach's alpha was used to test the ...

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 ...

Biofilms and bacteriological water quality in a domestic installation model simulating daily drinking water consumption
The biofilm formation potential of a drinking water supply system is related to the chemical, microbiological and hydrodynamic characteristics of water, and to the pipe materials in contact with water flow. The goals of this study were: to determine the biofilm dynamics in a model of four drinking water installations, to simulate daily household water consumption; to compare the biofilms ...

Health implications of lipopolysaccharide endotoxins in domestic container water used by rural households in South Africa
This study assessed the occurrence of endotoxins, cyanobacteria and enterobacteria in untreated drinking water stored in domestic water containers by rural households in South Africa. Endotoxins, cyanobacteria, total coliforms and Escherichia coli were measured in the following numbers and ranges in container-water samples: 4–54 μg l−1, 69–64,505 cells ml−1, 9,000–280,000 CFU/100 ml and ...
