Physicochemical Characterization and Evaluation of Seasonal Variations of Landfill Leachate and Groundwater Quality around Tanjaro Open Dump Area of Sulaymaniyah City, Kurdistan, Iraq

The current study is concerned with the primary environmental assessment of physicochemical characterization seasonal fluctuations in leachate Tanjaro open dump site Sulaymaniyah City, and its impact on quality groundwater. characteristics leachates were their high levels organic inorganic components toxicity because presence heavy metal concentrations. For almost all parameters, from area dumping has incredibly values. All metals present leachate, exception cadmium mercury, albeit at below respective permitted limits. revealed that Leachate 1 (L1) may be referred to as young whereas 2 (L2) 3 (L3) can old due pH It was indicated operating early stages stabilization. BOD5/COD around 0.63, highly biodegradable anaerobic phase. Groundwater, which contains little no matter, not found severely affected by monitoring wells located close dumpsites. conductivity, total dissolved solids, hardness, Mn, Fe some values went above WHO guidelines. Correlation analysis used a preliminary descriptive technique establish strength association between relevant variables. Some parameters discovered statistically significantly correlated one another, pointing connection these parameters.
