  • Drinking Water Quality

    The quality of drinking-water is a powerful environmental determinant of health. Drinking-water quality management has been a key pillar of primary prevention for over one-and-a-half centuries and it continues to be the foundation for the prevention and control of waterborne diseases. Water is essential for life, but it can and does transmit disease in countries in all continents – from the ...

  • Drinking Water Quality

    Drinking water or potable water is water of sufficiently high quality that it can be consumed or used without risk of immediate or long term harm. In most developed countries, the water supplied to households, commerce and industry is all of drinking water standard, even though only a very small ...

    Various advanced water treatment solutions are available for households as well as all types of facilities and industries. Water filtration provides users with valuable benefits that many don’t realize yet. Here are some of the advantages of water treatment solutions like an arsenic treatment system. Improved Water Quality A good arsenic filtration system ...

  • Treating Your Water with a Biological Filtration System

    Poor-quality drinking water can be an enormous hazard to your health. News stories in recent years have reported experiences of unfortunate individuals who have unknowingly consumed tainted or otherwise unsafe drinking water that included high levels of lead, calcium, arsenic, and other chemicals that have serious negative health effects. Before you take another sip of your water supply, consider ...

  • Organisational arrangements and drinking water quality

    This paper discusses the findings of a research project which explored the impact of varying organisational arrangements on drinking water quality in England and Wales, and the Republic of Ireland. It is established that drinking water quality has been of a consistently higher standard in England and Wales in comparison with the Republic of Ireland. It is also demonstrated that the associated ...

  • Evolution of regulatory targets for drinking water quality

    The last century has been marked by major advances in the understanding of microbial disease risks from water supplies and significant changes in expectations of drinking water safety. The focus of drinking water quality regulation has moved progressively from simple prevention of detectable waterborne outbreaks towards adoption of health-based targets that aim to reduce infection and disease to ...

  • Effect of agro-activities on drinking-water quality in Bangladesh

    Fifty-nine samples of drinking water were collected from various locations in Bangladesh to assess the impact of agricultural practices on groundwater quality. The basic groundwater quality parameters, such as pH, total dissolved solids, iron, sodium, chloride, sulfate, fluoride and arsenic were analysed. In addition, the presence of excess fertilizers was monitored by measuring levels of ...

  • Turbidity tubes for drinking water quality assessments

    Turbidity tubes have been considered to be the field method of choice for drinking water quality monitoring in resource-limited contexts because of their relative simplicity and low cost in comparison with conventional (nephelometric) turbidimeters. These tubes utilise the principle of visual extinction of a submerged target for turbidity determination and were therefore thought to be subject to ...

  • Drinking water quality monitoring using trend analysis

    One of the common quality parameters for drinking water is residual aluminium. High doses of residual aluminium in drinking water or water used in the food industry have been proved to be at least a minor health risk or even to increase the risk of more serious health effects, and cause economic losses to the water treatment plant. In this study, the trend index is developed from scaled ...

  • Managing water quality impacts from drought on drinking water supplies

    Droughts, which are difficult to predict, are a natural feature of the hydrology in most regions. Climate change, however, has the potential to increase the frequency and magnitude of future droughts. While the lack of water availability during droughts is widely publicized, there are equally severe water quality impacts that occur during and after droughts as well. Recent droughts have led to ...

  • The Future of Drinking Water

    Predicted future growth in population numbers and rising sea levels mean demand for drinking water will continue to increase just as the natural availability of freshwater decreases. It is likely that brackish groundwater will be an important source of drinking water in the future, but the current methods used to produce fresh water from this source are expensive in terms of their energy use and ...

  • Water quality for irrigation and drinking water use of Aflaj in Oman

    The Sultanate of Oman is an arid country with scarce water resources mainly consisting of groundwater. Aflaj are artificial canals constructed centuries ago to transfer horizontally the groundwater to a location at the surface. The water quality of these Aflaj is a very important factor to be considered for healthy and safe use of this water. This paper aimed to study the characteristics of the ...

  • Hydrodynamic modelling and forecasting of microbial water quality in a drinking water source

    Faecal contamination often enters drinking water sources through emergency discharges, which occur as a result of technical malfunctions or a hydraulic overload of the sewer system during periods of heavy rain. In October–November 2012, several emergency discharges entered Lake Rådasjön – a drinking water source for Gothenburg, Sweden. To describe and forecast the ...

  • Drinking Water Standards

    The most important point of departure for drinking water standards is the World Health Organisation Guidelines for Drinking Water Quality. These are widely used throughout the world with the exception of parts of North America. WHO’s Guidelines have evolved over a period of 50 years from standards to guidelines, reflecting the fact that they have no legal force. The WHO emphasises that it ...

  • Assessing clarity of message communication for mandated USEPA drinking water quality reports

    The United States Environmental Protection Agency mandates that community water systems (CWSs), or drinking water utilities, provide annual consumer confidence reports (CCRs) reporting on water quality, compliance with regulations, source water, and consumer education. While certain report formats are prescribed, there are no criteria ensuring that consumers understand messages in these ...

  • Drinking water in rural India: a study of deficiency, quality and some social implications

    There is no doubt that accessibility of drinking water for rural households in India has increased over the decades, partly owing to concerted efforts by the state and partly owing to a rise in income of the people. Public provision of drinking water is primarily made through the tap whereas private provision is through the tube well. Households opt more for a tube well than for other sources ...

  • Drinking water quality control: control charts for turbidity and pH

    Water treatment processes are required to be in statistical control and capable of meeting drinking water specifications. Control charts are used to monitor the stability of quality parameters by distinguishing the in-control and out-of-control states. The basic assumption in standard applications of control charts is that observed data from the process are independent and identically ...
