بررسی عوامل موثر بر هیدروژیوشیمی آبخوان دشت چهاردولی (استان کردستان) با استفاده از نمایه های اشباع و دیاگرام های ترکیبی

In this study for determination of Hydrogeochemical processes, Hydrochemical faciec, ionic ratios and saturated indices of CHahardolly aquifer. 60 samples of groundwater were taken from wells and physicochemical analyses have been used. The quality of groundwater has been effect strongly by tectonic processes and geology features. Hydrothermal activities Eocene period have increased ionic concentration and decreased PH of groundwater. The dominant type of water is bicarbonate calcium. Weathring of geology is m main controling factor of groundwater chemistry. Increasing the concentration of sodium and sulfate in a part of the aquifer is the result of wastewater and human activities. Same software RockWork, PHREEQC and ArcGIS for best decision have been used.
