Elisabeth orphanage "kinderen van India" - Case Study
The Dutch based foundation "Kinderen van India" has set up an orphanage in 1989 in Pendra Road in the province Chhattisgarh (central India). The last two years the number of cases of waterborn diseases increased sharply. In particular the number of infectious diseases such as typhoid fever has risen sharply. The drinking water is extracted from a well located on the property. This source should ...

Removal of arsenic from anthropogenic aqueous media: an analytical review with particular reference to solvent extraction technique
Arsenic is an environmental toxicant, which is known to cause serious ailments to humans and its presence in drinking water poses grave threat to millions of people all over the world. Apart from being drinking water pollutant, arsenic poses another dimension of problem in the recovery of metals from some of the sulfide ores, namely copper pyrites and galena. These were the two main reasons to ...

Comparison of extracts and toxicities of organic compounds in drinking water concentrated by single and composite XAD resins
We compared extracts and toxicities of organic compounds (OCs) in drinking water concentrated by composite XAD-2/8 resin (mixed with an equal volume of XAD-2 and XAD-8 resins) with those extracted by single XAD-2 (non-polar) and XAD-8 (polar) resins. Drinking water was processed from raw water of the Han River and the Yangtze River in Wuhan section, China. The extraction efficiency of all ...

Large Volume Splitless Injection Using an Unmodified Split/Splitless Inlet and GC-TOFMS for Pesticides and Brominated Flame Retardants
Abstract Large volume splitless injection for gas chromatography typically requires a special injection port, for example, a programmable temperature vaporizer (PTV), but an alternative setup using concurrent solvent recondensation–large volume splitless injection (CSR-LVSI) and a split/splitless injection port has been reported. This technique was used here, both with and without sample ...

A new immunomagnetic bead separation–surfactant extraction treatment protocol for rapid and sensitive quantitative PCR detection of Cryptosporidium parvum DNA
The Cryptosporidium oocyst is encased in a robust wall that is extremely resistant to detrimental environmental factors such as chlorine used to disinfect potable water. Therefore, extracting oocyst DNA is not a trivial undertaking. Standard procedures used to extract DNA from oocysts, such as freeze–thaw (F/T) methods and DNA purification kits, are time-consuming and expensive and are ...

Performance of Moringa oleifera extracts and Sudfloc as coagulant aid in raw water treatment in Mauritius
Coagulation experiments were done using raw water samples from two treatment plants (herein referred to LMTP and LNTP) in Mauritius in jar tests using Moringa oleifera (MO) extract and Sudfloc. Both coagulant aids reduced alum consumption. Sudfloc was required in low concentration as compared to crude extracts of MO. On samples from LMTP, salt extract of MO (MOSE) was six times more efficient ...

Development of a risk-based approach for better protection of drinking water catchments in Flanders (Belgium)
Around 70% of the drinking water produced by De Watergroep (a Belgian public water company) is extracted from 83 groundwater pumping sites. To control the risks that endanger the drinking water supply and for the groundwater extracted to be as pure as possible, a risk-based approach for the protection of the catchment areas is developed, as part of the water safety plans. The approach ...

Drinking water treatment residuals as an amendment to alkaline soils: Effects on the growth of corn and phosphorus extractability
Abstract: Drinking water treatment residuals (alum) are waste products of water purification that have potential for environmental remediation as a soil amendment and a potential plant growth medium. In this study, the influence of added Drinking water treatment residuals on the extractability and availability of phosphorus to plants; determination of the agronomic rate of alum to different ...

Analysis of pesticide residues in drinking water samples using solid-phase micro-extraction (SPME) coupled to a gas chromatography-electron-capture detector (GC-ECD)
The headspace solid-phase micro-extraction (HS-SPME) method with polydimethylsiloxane (PDMS, 100 μm) fiber is a cost-effective technique for the determination of different pesticide residues in environmental and biological samples followed by a gas chromatography-electron-capture detector (GC-ECD). In the present study more than 147 water samples collected in and around Lucknow city were ...

Sustainable use of nature is good for the economy
Nature provides all kinds of goods and services that offer economic opportunities, such as a water, food, building materials and recreation areas. However, this 'natural capital' is under pressure due to the growing world population and increased economic prosperity. Businesses, civic organisations and governments are therefore looking for sustainable ways to profit from natural capital, now and ...

Who does water actually belong to? - Pipe location for tracking down theft of water in Peru - Case Study
Water makes you important Water is nowadays such a precious commodity that some countries which in fact already have too little drinking water for their own demands are selling rights to water sources to international companies or are even exporting water they desperately need themselves. The better the water supply functions in a country, the lower the risk of a drinking water shortage ...
