Hydrochemical Characteristics of Rainwater in Ramallah District

摘要

The hydrochemical variability of rainwater in Ramallah District in theWest Bank was studied through two rainwater sampling campaigns of the rainyseasons of 2007 and 2008 in order to determine its hydrochemical characteristics.The major ions of twenty two rainwater samples: Ca~(2+), Mg~(2+), Na~+,K~+,Cl~-, SO_4~(2-),NO_3~-and HCO_3~-were analyzed. Sodium Potassium concentrations showincreasing amounts in the Western parts more than the Eastern parts. The Nitrateconcentrations is increasing in the Western parts of the study area. Sulfate showsvariability, but its concentration is noticeably increasing in Western areas due toits close to the Mediterranean Sea. Three types of Rain water were found: Na-Cl,Na-HCO_3 and Ca-HCO_3. Most of the Rainwater samples fall into the normal earthalkaline water group with prevailing bicarbonate and sulfate or chloride. EC andTDS values show an increasing trend and has the linearity of TDS = 0.5 EC.
