Hydro-Geochemical Characteristics and Evaluation of Drinking Water Quality in Gaza Strip

Mohammad AlKhateeb

Groundwater is the main water resource used for drinking and irrigation purposes in the region. As groundwaterquality assessment is an essential component for its safer use. The aim of this paper is Hydro-geochemicalCharacteristics and evaluation of drinking water quality in Gaza strip .For this study, were collected from 102sample for drinking wells in 2009. Water quality classification was derived through a multitude of diagram methodsand equations. The results of analysis showed that the groundwater was chemical highly enriched with Na+ and Clanindication of seawater intrusion into the aquifer as also supported from the Na-Cl signature on the Piper diagram.Results of this study indicate that the groundwater in the region is mainly of NaCl,CaHco3-and NaHco3-.Resultsreveal that salinity and the major elements concentrations, increase towards groundwater flow. The saline load ofthese waters is in first place controlled by chloride, sodium and calcium concentrations. The spatial changes of ionicratios of rCa2+/(rHCO3- + rSO42-) and the relationship between sodium and chloride in the coastal area in 2009indicate that the aquifer experienced seawater intrusion. study showed that by understanding correlation matrixbetween the chemical elements of drinking water and compared with sea water, we find that there is a strongcorrelation between chloride, calcium, magnesium, sodium, and this was due to seawater intrusion. The geochemicaldata, presented in the form of GIS-based geochemical maps.Email addresses:
