Comparative study of physico-chemical parameters of drinking water from some longevity and non-longevity areas of China
There is an obvious regional longevity phenomenon in China and many longevity counties are located in South China. This study was carried out to find the characteristics of elemental contents of drinking water in longevity areas in South China and the differences to non-longevity areas in China. A total of 128 drinking water samples were collected from longevity areas in South China (n = 40), ...

Arsenic concentration in drinking water of Bihar: health issues and socio-economic problems
More than 10 million people residing in 13 districts of the state of Bihar are facing the acute problem of arsenic contamination in drinking water. The objective of this paper is to quantify arsenic in drinking water, and to understand the associated health problems, health costs and socio-economic issues in the region. In the study, a field test kit was used to test the arsenic concentration ...

High fluoride drinking water in Gokwe, northwest Zimbabwe
More than 200 million people worldwide are exposed to excessive fluoride in drinking water. According to the World Health Organization, the optimal concentration range of fluoride in drinking water is 0.5 to 1.5 mg/L. Above this range, populations may contract dental fluorosis or, in severe cases, crippling skeletal fluorosis. In the Gokwe area in NW Zimbabwe, where drinking water contains up ...

Comparing electrochemical disinfection with chlorination for inactivation of bacterial spores in drinking water
Drinking water disinfection techniques without the dosage of chemicals are regarded as more advantageous in terms of costs and practical use. Here we investigated the efficacy of electrochemical disinfection for inactivation of Bacillus subtilis spores – a model microorganism of highly resistant pathogens. The effect of electrochemical disinfection with TinO2n−1 ceramic electrodes ...

Removal of arsenic from drinking water using modified fly-ash bed
The removal of arsenic from drinking water by filtration through modified fly-ash bed is discussed. The preparation and characteristics of the bed material and the effects of different parameters like pH and the presence of other constituents are described. Various arsenic compounds in synthetic mixtures as well as drinking water samples containing arsenic have been investigated. The ...

Is Australia’s Drinking Water Safe?
Modular water treatment can help bring safe drinking water to remote, underserved communities The quality of drinking water in Australia is generally high, with 93% of households having access to clean, safe drinking water. Yet, while this is true for urban households, almost 200,000 people living in remote parts of the country do not have the same luxury. A study published earlier this year in ...

Boron removal from brackish water by reverse osmosis and nanofiltration membranes: application of Spiegler–Kedem model and optimization
Drinking water should contain certain chemicals only in limited quantities. Boron, one of these chemicals which is considered as a threatening compound and is difficult to eliminate from water. The purpose of the research is to study the major role of reverse osmosis (RO) and nanofiltration (NF) process which can contribute to the removal of this inorganic element from brackish water. For ...

Affinity adsorption for the removal of organic micropollutants in drinking water sources; proof of principle
Sources for drinking water (DW) production contain increasing concentrations of organic micropollutants, such as pesticides and pharmaceuticals. Traditional purification processes are not suitable for their removal or conversion, but even sophisticated technologies, like advanced oxidation processes and membrane filtration, are not able to efficiently remove all compounds from DW. For ...

Technology for treatment of groundwater simultaneously containing iron, manganese, ammonium and organic matter
The groundwater used as drinking water often contains unacceptable amounts of iron and manganese compounds and ammonium ions. These substances are efficiently removed using conventional technologies (aeration and filtration through granular media filters). However, the efficiency is drastically reduced for water containing considerable amounts of organic matter, which usually enters the water ...

Direct potable reclamation in Windhoek: a critical review of the design philosophy of new Goreangab drinking water reclamation plant
Direct drinking water reclamation from the Goreangab reclamation plant, has been a reality in Windhoek, Namibia since 1968. Potable reclamation is a fixed part of the water supply and waste water has become an indispensible resource for the survival and continued growth of the city. The multi barrier concepts that were applied 40 years ago have been refined over many years. Improvements in ...

Biodegradation of natural organic matter in long-term, continuous-flow experiments simulating artificial ground water recharge for drinking water production
The role of biodegradation in the attenuation of natural organic matter (NOM) was investigated in long-term experiments that simulate artificial ground water recharge (AGR) for drinking water production. Lake water containing 5.8 mg L–1 total organic carbon (TOC) was continuously fed into an 18.5-m-long sand column. During the 941 d of operation, on average 76 and 81% of TOC was removed within ...

Semi-volatile organics in drinking water using EPA method 525.2 optimized for greater sensitivity
The US EPA Drinking Water Manual contains the methods used to identify and quantify regulated and unregulated organic drinking water contaminants. Included in this manual is Method 525.2, a Gas Chromatographic/ Mass Spectrophotometric (GC/MS) technique for the determination of semi-volatile organic compounds. Method 525.2 can be used for the identification and quantification of a group of ...

Dynamic factor analysis for estimating ground water arsenic trends
Received for publication March 14, 2009. Drinking ground water containing high arsenic (As) concentrations has been associated with blackfoot disease and the occurrence of cancer along the southwestern coast of Taiwan. As a result, 28 ground water observation wells were installed to monitor the ground water quality in this area. Dynamic factor analysis (DFA) is used to identify common trends that ...

Why Everyone Should Drink Filtered Water
Your body is made up of a lot of water; 60 to 65 percent to be exact. The water that you drink each day helps to replenish your body and give you strength. But, if you’re drinking water that contains heavy amounts of chemicals, metals, and other harmful ingredients, what does that say about your body composition? Untreated water could be responsible for a number of different health and ...

Facts about Fluoride in Water
Previously, the only route of exposure to fluoride was by drinking water or food that contained natural sources of fluoride. Currently, exposure to fluoride comes from more sources including fluoridated dental products such as toothpaste and mouthwash, as well as the addition of fluoride to drinking water, for reducing tooth decay. Some bottled water products (such as spring water) can contain ...
