Abstract Introduction: Determining the quality of water is particularly important in water resources management, and monitoring and zoning it are considered as a significant principle to be taken into account in planning. Schuller method is the commonest way to determine the quality of water. The present study was conducted in order to determine the quality of drinking water using Schuller mod...

Abstract Using inductively-coupled plasma mass spectrometry (ICP-MS), we measured the concentrations of thallium and uranium in local water resources from three villages (Ćelije, Draž, and Potnjani) in eastern Croatia, with the aim to determine if they were associated with the levels of these same elements in the serum, urine, and hair collected from the residents of this area. The exposure of ...

Several authors have suggested that it is safe to raise the health standard for nitrate in drinking water, and save money on measures associated with nitrate pollution of drinking water resources. The major argument has been that the epidemiologic evidence for acute and chronic health effects related to drinking water nitrate at concentrations near the health standard is inconclusive. With resp...

Due to decreases in the availability and quality of traditional water resources, harvested rainwater is increasingly used for potable and non-potable purposes. In this study, we examined the effect of conventional roofing materials (i.e., asphalt fiberglass shingle, Galvalume(®) metal, and concrete tile) and alternative roofing materials (i.e., cool and green) on the quality of harvested rainwa...

Arsenic contamination in drinking water resources is of major concern in the Ganga delta plains of West Bengal in India and Bangladesh. Here, several laboratory and field studies on arsenic removal from drinking water resources were conducted in the past and the application of strong-oxidant-induced co-precipitation of arsenic on iron hydroxides is still considered as the most promising mechani...

of dams and network of irrigation canals have received considerable attention in the past and health impact assessments of such projects have also been conducted1, 2. Large-scale construction activities often bring about considerable ecological changes and create new mosquito breeding habitats. Moreover, increased supply of water may bring about an overall behavioural change in the community le...

A great number of organic and inorganic substances pollute the water of the Rhine. The greatest concentration is formed by the chlorides, as their quantity exceeds that of the suiphates by about 50 per cent. At the German—Dutch frontier, the mean annual value of the chloride charge of the river amounts to approximately 350 kg/s C1. About 40 per cent, or 130 kg/s, of this quantity are residual s...

(eds M.C.S. Wopereis et al.) 265 supply sufficient water for drinking water and irrigation. Exceptions are the Volta River basin in West Africa and the Orange and Limpopo River basins in Southern Africa, where population density and large-scale irrigation systems put great strains on water resources availability (Ravenga et al., 2000). There is large untapped irrigation potential in SSA. IFPRI ...

Since water resources of desert Naein City are very limited, a approach which saves water resources and meanwhile meets the needs of the greenspace for water is to use city’s sewage wastewater. Proper treatment of Naein’s sewage up to the standards required for green space uses may solve some of the problems of green space development of the city. The present paper closely examines available st...

It is widely accepted that characterizing the spatio-temporal trends of water quality parameters and identifying correlated variables with water quality are indispensable for the management and protection of water resources. In this study, cluster analysis was used to classify 56 typical drinking water reservoirs in Zhejiang Province into three groups representing different water quality levels...
