Access to safe drinking water and human health: empirical evidence from rural Bhutan
Provision of safe drinking water is essential for the promotion of human well-being. This paper makes an attempt to examine the patterns of access to drinking water, identify and analyze the factors that influence households access to safe drinking water sources, and analyze factors determining the extent of households travel to fetch drinking water, and assess the effects of access to safe ...

Caries affected by calcium and fluoride in drinking water and family income
Water quality and socioeconomics influence caries in populations. This study broadens previous studies on how caries is associated with fluoride and calcium in drinking water and with family income by quantifying the combined effect of the three independent variables. The effects of calcium and fluoride can be described as independent effects of the two ions or, alternatively, in the form of ...

Determination of micro and macro elements in waters with the ELAN DRC-e
The ability of reaction cell technology to reduce the effects of spectral interferences is well-known, but another, lesser-known capability also exists: extending the dynamic range. This is accomplished by adjusting the bandpass parameters with no gas in the cell. Because the bandpass parameters can be adjusted on a per-mass basis, sensitivity can be reduced on selected isotopes without affecting ...

Mold Odor Analysis Using a Purge and Trap Multimatrix Autosampler
Abstract Taste and odor are widely associated with drinking water quality. Musty odors, caused by compounds such as geosmin and 2-methylisoborneol (MIB), may lead consumers to believe their water is unsafe. These compounds are byproducts of the growth of blue-green algae and other microbes. Since consumers rely on taste and odor as primary indicators for water safety, water suppliers take steps ...

Environmental governance, service quality and drinking water: a participatory diagnosis conducted through a water ombudsman
This study focuses mainly on the search for new-generation models of democracy based on the principles of governance and the quality of public drinking water services. We analyse the participatory initiatives implemented by the Argentinian government over the past twenty years and look at how these have led to alternative models for utility operators. The study describes users’ perceptions ...

Potential Drinking Water Contamination Analyzed
A comparison of more than 100 large US cities showed pollution from point and nonpoint sources Too often, surveys of water quality in the United States have been regionally inconsistent patchworks that neglect many unregulated contaminants. A granular study of potential source water contamination in the largest cities in the U.S. has been lacking. New research in the journal Nature, however, ...

Assessment of Trace‐Element Impacts on Agricultural Use of Water from the Dan River following the Eden Coal Ash Release
Catastrophic events require rapid, scientifically sound decision‐making to mitigate impacts on human welfareandthe environment. The objective of this study was to analyze potential impacts of coal‐ash‐derived trace elements on agriculture following a 35,000‐tonne release of coal ash into the Dan River at the Duke Energy Steam Station in Eden, NC. We performed scenario calculations to assess ...

Coping with the daily challenges of routine water analysis
Analyzing different types of water samples on a regular basis presents several challenges for analysts. Depending on the type of lab (e.g., municipal or water bottling facilities), the number of samples to be analyzed can vary significantly. Every day such laboratories receive hundreds of samples that must go through pH, conductivity, and alkalinity testing, among others. If additional tests ...

Volatile Organic Compounds in Every Day Food
Abstract Volatile Organic Compounds (VOCs) have been analyzed in drinking water and pharmaceuticals extensively in recent years. Now, VOCs in food products have became a major interest among researchers. Utilizing an Atomx automated VOC sample prep system in conjunction with a gas chromatograph-mass spectrometer (GC/MS) will allow for the determination of VOCs in food products. The automated ...

Fungi in biofilms of a drinking water network: occurrence, diversity and mycotoxins approach
Results showed that 75% of the analyzed samples in a drinking water network were positive for fungi, in a range of 1–3,000 CFU/mL. Identification resulted in nine species of fungi and four species of yeasts being listed: Bjerkandera, Penicillium, Paraconiothyrium, Paecilomyces, Debaryomyces, Rhodotorula and Cryptococcus. Although yeasts showed higher traceability than filamentous fungi, the ...

Meeting the US Environmental Protection Agency Drinking Water Requirements with a UV/Persulfate Analyzer
Abstract The rapid and precise measurement of organic carbon in trace levels of water is of interest to the pharmaceutical, drinking water and environmental industries where regulations restrict the amount of discharge or contamination. Total Organic Carbon (TOC) analysis is considered an effective indicator of organic contamination in water. Since the US EPA set limits on Disinfection ...
