In this study, the quality of groundwater aquifer of Gavkhooni basin was investigated in agriculture. For this purpose, water quality data related to 96 wells prepared by Isfahan Regional Water Authority during the statistical period 2015-2016 were used. In this study, sodium parameters, electrical conductivity, chloride, hydrogen bicarbonate and sodium absorption ratio (SAR) were used. Then, g...
This article presents the first comprehensive review and analysis of the uptake of the Canadian Drinking Water Quality Guidelines (CDWQG) across Canada's 13 provinces and territories. This review is significant given that Canada's approach to drinking water governance is: (i) highly decentralized and (ii) discretionary. Canada is (along with Australia) only one of two Organization for Economic ...
Groundwater resources are important part of the sweet water available to humans. The present study studies and evaluates the quality of water resources of karstic basin of Roein Esfarayen. For this purpose, sampling of water from water sources was carried out and groundwater quality of the area was evaluated in terms of drinking, agriculture and industry using Schoeller, Wilcox and Langelier di...
This study was conducted over seven villages near Darbandikhan district including (2) wells and (5) springs. It covers more than 60 km, to assess the suitability of ground water quality for drinking purpose using water quality index through investigating of different wells and springs; this technique is very useful tool for quick assessment for any water system. This was done by subjecting the ...
rivers are one of the most valuable aquatic ecosystems that their physiochemical properties and the biology of their organisms have strong interactions. one of the major rivers in iran, which covers a variety of ecosystems, is called tajan river. in this research, the effect of different pollution sources on water quality of this water body was investigated. samples were collected in seven diff...
Introduction: Monitoring and controlling water resources and using health risk assessment approaches for water pollutants are essential for health promotion programs. This study aims to determine the water quality status and its spatiotemporal variation across the Kan River Basin, explore the interrelationship between surface and groundwater quality indices, and assess the nitrate health risk i...
Solar water heating system technology is described and the scale of the International solar water heater market is surveyed. New product developments for both direct solar water heating and solar boosted heat pump water heating are outlined. Procedures adopted by the International Standards Organisation for assessing solar water heater performance and quality are discussed.
Background and Objectives: Kidney patients in each dialysis cycle are exposed to extremely large volume of water, which is in direct contact with the patient’s blood. Hence, the occurrence of any type of contamination in the water used can be very toxic to patients. Thus, quality of water plays an important role in patient well-being. The aim of our study was to investigate the quality of water...
the present study has been conducted to determine the surface water quality of urban area in savar, dhaka, bangladesh by determining some water quality parameters (transparency, temperature, ph, ec, eh, do, tss, tds, ts, bod5, cod, toc, cl-, br-, so4-2, no3-, no2-, po4-3, tp, hco3- and total alkalinity) as well as the status of phytoplankton’s community in the water from two lakes (tiger lake a...
