Today, bottled and tap drinking water mainly originates from underground waters which might contain considerable amounts of naturally occurring radionuclides. One of the most toxic radionuclide in drinking water is 226Ra. Following the metabolism of calcium, it could be deposited into the bone where, in sufficient amount, it could cause bone sarcoma. Although current drinking water preparation ...

in recent years, a potential connection between human intake of aluminum and alzheimer’s disease has drawn attention to the aluminum concentration in drinking water. it is therefore of interest to investigate the aluminum concentration m drinking water, produced under different circumstances. a random selection of 152 water samples were taken by the supply source including ground, surface and a...

The availability of organic carbon is considered the key factor to regulate microbial regrowth in drinking water network. However, boreal regions (northern Europe, Russia, and North America) contain a large amount of organic carbon in forests and peatlands. Therefore, natural waters (lakes, rivers, and groundwater) in the northern hemisphere generally have a high content of organic carbon. We f...

Although Semantic Web builds on well-established foundations and we are witnessing its expansion across multiple domains, the community has todate been rather keen on building hybrid ontology-based water quality management systems. Our vision is to build a pure Semantic Web framework for effective management of water quality. In line with this, an SSN-based ontology for water quality management...

The Environment Agency (EA) is an executive nondepartmental public body that is sponsored by the UK government’s Department for Environment, Food and Rural Affairs (DEFRA). Part of EA’s remit is to safeguard the natural environment of England, protecting and improving the environment to create better places for people and wildlife. Similar Agencies perform equivalent functions in the other, dev...

PURPOSE The purpose of this study was to classify brands of bottled water by manufacturer assigned labeling to verify the concentration of fluoride for those brands that claim to contain fluoride, and to determine the existence and concentration of fluoride for those brands that do not cite fluoride or list it as undetermined on the product label. METHODS A convenience sample of bottled drink...

Background: One of the most significant radionuclides in natural drinking waters is 226Ra and its decay products. It is potential of health problems, including cancer risk. In this study, the effect of 226Ra concentration in 28 drinking water samples collected from the North Guilan province was investigated. Materials and Methods: The activity concentrations of 226Ra were measured by using of r...

BACKGROUND: Legionella spp. in groundwater sources have been reported to be the cause of waterborne infections, specifically Legionnaire’s Disease and Pontiac Fever. Legionellae are known to be ubiquitous in surface waters, but much less is known about their occurrence in groundwater, which is the source of potable water for millions in North America. Federal drinking water regulations may not ...
