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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Water aggressiveness and hydrodynamic effects on the fibres release in asbestos-cement pipes for public water supply
SEM and TEM analyses of drinking water samples, collected during three years (1988, 1989 and 1990) from some Asbestos-Cement (A/C) distribution systems in Veneto Region (Italy), have shown that the release of fibres, with length greater than 10 μm, is, on average, quite low. Moreover, the asbestos concentration is not strictly dependent on Aggressiveness Index (A.I.) in the range ...

Water Monitoring in drinking water plants - The Comparison Between On-Line TOC Analysis and the Permanganate Oxidation Method
Introduction The role ofthe plants providing water is not restricted to the collection of water from areas where abundantly available and then distribution to the consumer. In reality, it involves a serious commitment to the guarantee of waterwhich is high quality. For this reason, drinking water facilities make use of conditioning plants which are equipped with chemical lab oratories that ...

How the Aquamonitrix real-time nitrate and nitrite analyser allowed a drinking water supplier to lift a long-standing Do Not Consume notice - Case Study
Compared with market-leading UV-based nitrate analysers, Aquamonitrix offers a key advantage in statutory limit monitoring applications at the outlet of drinking water treatment plants. In addition to providing high-accuracy, real-time nitrate monitoring, Aquamonitrix simultaneously provides a specific, high accuracy real-time nitrite measurement, with a lower limit of detection of just 0.05 ...
