Microbiological water quality of the Nišava River

Microorganisms are the ideal indicators of the organic pollution of the surface waters because of their ability to promptly respond to environmental changes. Due to poor economic situation and lack of law implementation, most wastewaters in Serbia are released directly into a surface water recipient without any, or a limited, treatment. This practice has created numerous highly polluted ...

Microbiological quality of chlorinated water after storage in ceramic pots

Household water treatment with sodium hypochlorite has been shown to reduce self-reported diarrheal disease in developing countries. Reported hypochlorite use, time since treatment, total chlorine residual (TCR), and E. coli concentration results from 589 household surveys in rural Kenya were analyzed to quantify the effect of exceeding recommended 24 hour post-treatment water storage time ...

Microbiological quality of ice and ice machines used in food establishments

The ice used in the food industry has to be safe and the water used in ice production should have the quality of drinking water. The consumption of contaminated ice directly or indirectly may be a vehicle for transmission of pathogenic bacteria to humans producing outbreaks of gastrointestinal diseases. The objective of this study was to monitor the microbiological quality of ice, the water ...

An assessment of microbiological water quality of six water source categories in north-east Uganda

Target 7C of the Millennium Development Goals is to “halve, by 2015, the proportion of people without sustainable access to safe drinking water and basic sanitation”. However, the corresponding indicator measures the “proportion of population using an improved drinking water source”. This raises the question of whether “safe” and “improved” can be used interchangeably. This paper tests this ...

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 ...

A novel technology to improve drinking water quality: a microbiological evaluation of in-home flocculation and chlorination in rural Guatemala

An estimated 1 billion persons in low-income countries do not have access to improved drinking water. Chlorine, a useful water treatment agent, is less effective in turbid water, and lacks a visible effect, limiting its acceptability. A product incorporating precipitation, coagulation, flocculation, and chlorination technology (combined product) to reduce microbial, organic and heavy metal ...

Assessment of water and seafood microbiology quality in a mangrove region in Vitória, Brazil

Mangroves are vital part of the local economy for some communities in the region of Vitória, Brazil. Oysters, mussels, and crabs, which are naturally abundant in the mangroves, are harvested and largely consumed in restaurants and by the population. In recent years, unusually high rates of annual gastroenteritis cases have been reported in the region suggesting an association between the ...

Coupling microbiological testing and sanitary surveys in drinking water quality programs: results from Capiz Province, Philippines

Developing countries often struggle to conduct laboratory-based water quality testing programs due to a lack of financial and technical resources. However, inexpensive, accurate, field-based tests are being developed which have the potential to overcome this barrier. This paper provides the results of an initiative by the Provincial Health Office in Capiz, Philippines, to conduct a first-ever, ...

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 ...

Water Quality in South Asia

Abstract:There are significant differences in the water chemistry of the Himalayan and southern peninsular rivers. Large and small rivers also show different types of water quality. Liquid and solid waste definitely contribute to water quality in urban centres such as Delhi and even coastal regions, as near Mumbai, are affected by waste discharges. The sub-continent also suffers from problems ...

Improving the microbiological quality of the Ruhr River near Essen: comparing costs and effects for the reduction of Escherichia coli and intestinal enterococci

After rain events in densely populated areas, combined sewer overflows (CSOs) can have severe health-related effects upon surface water quality, as well as diffuse overland runoff and wastewater treatment plants (WWTPs). All of these sources emit pathogens and fecal indicator bacteria into the surface water, which the EU Bathing Water Directive addresses by giving threshold values for the ...
