pH effect on species variations was tested using PHREEQC modeled main species. Two redox states of groundwater were identified using USGS redox scheme. d18O varied between -5.89‰ and -3.32‰ while d2H ranged between -36.98‰ and -20.42‰. d2H/d18O ratios revealed the groundwater was of meteoric origin. d-Excess suggested minimal impact of secondary evaporative process...
