introduction more than 90% of drinking water in cities around the world and about 40% of the agricultural water supply from groundwater resources.,thus, groundwater quality consideration issue is inevitable . one of the most important parameter which can show the quality of drinking water is nitrate concentration. nitrate enters the groundwater and surface water through the decomposition of hum...

one of the main aims of water resource planners and managers is to estimate and predict the parameters of groundwater quality so that they can make managerial decisions. in this regard, there have many models developed, proposing better management in order to maintain water quality. most of these models require input parameters that are either hardly available or time-consuming and expensive to...

This study determined the total and speciated arsenic (As) concentrations and other health-related water quality parameters for unraveling the health risk of As from drinking water to humans. Groundwater samples (n = 62) were collected from three previously unexplored rural areas (Chichawatni, Vehari, Rahim Yar Khan) of Punjab in Pakistan. The mean and median As concentrations in groundwater we...

Umm Er Radhuma Aquifer (UER) is the most important groundwater aquifer in Saudi Arabia, extending over 1.6 M·km2 eastern part of Arabian Peninsula, forming main throughout Rub’ Al-Khali (RAK). Groundwater salinity increased from west to east, reaching more than 27,000 mg/L near border with United Arab Emirates, where a Na+-Ca2+Clˉ- water type dominated. Gibbs diagrams indicated that dissolution...

Water scarcity in the hill tract districts of Bangladesh becomes acute dry season as most streams, primary source water, up. However, groundwater, where available, can supply water throughout year. In this study, a total 37 samples were collected and analyzed from shallow (34) deep (3) wells Khagrachhari Sadar to assess their geochemical type suitability for drinking using multiparameter ground...

Potassium (K) and sodium (Na) coexist on the soil exchange complex and soil solution. Both cations may exert antagonistic or synergistic effects on mutual absorption and translocation within plants, particularly under saline and saline-sodic field conditions. This study investigated the role of K in alleviating the adverse effects of Na on wheat [Triticum aestivum (L), Iquilab-91] grown at two ...
