Palestine is not like other countries; it has its special situation because of the Israeli occupation. The closure and segregation of the main roads of the Palestinian, leading to complicate the solid waste management problem and resulted in the usage of alternative uncontrolled dumping sites which may be polluted the soil and the ground water. The vulnerability map of West Bank notice that many Palestinian cities especially Nablus city have high vulnerability. Neither short nor long term effect of MSW on soil and ground water in Palestine were not adequately evaluated and there is need to explore these effects and impacts. So the aims for this study are: evaluate the temporal and spatial variations of MSW leachate in landfills, evaluate the impacts of MSW leachate on soil, and may be simulate the impacts of MSW leachate on ground water. These aims achieved by establishing a model similar the real dump site, which consists of: * Leachate extraction columns * Leachate application to soil columns Laboratory analyses: * Leachate: the samples were analyzed for MSW leachate parameter which are: pH, EC, TSS, TDS, BOD5, Ca, Mg, Na, K, CO3, HCO3, alkalinity, hardness, Sulfate, Phosphate, Nitrate, Cl, and Iron. * Soil: the soil properties which we tested were classified under two different categories; physical and chemical properties. • Physical analyses are: pH, EC, sieve analysis, hydrometer test. • Chemical analyses are: Nutrition that consists of K, Nitrite, and Phosphorus. Salt source that consists of Na, Ca, Mg, Cl. The results of this study demonstrated that • TSS and TDS of MSW leachate were increased with MSW depth and decreasing with increasing water addition. • SAR values of the soil impacted by MSW leachate and in all columns tested increased slightly with depth but remained within the excellent range of soils suitable for agricultural development. • Removal of pollutants from MSW leachate by passage through a soil. • Statistical analysis of quality data collected showed that responsive functions of elements under consideration using multiple liner regression were possible and adequately acceptable and can be used to predict those elements as a function of MSW elevation and extent of precipitation.
