Abstract: “For effective preservation of environment and required protection of groundwater, the Municipality of the Holy Capital (Makkah), Kingdom of Saudi Arabia plans to appropriately and properly close the old landfill at Muassim area in Makkah with a particular synthetic cover layer that prevents rainwater from reaching the very inside of the landfill and mixing up with its components. This affects subsequently the quality of the groundwater in the nearby valleys (Wadis). Furthermore, for safeguarding the air environment, the said Municipality intends to construct a network for the collection of gases and considering the possibility of making use of it in energy production. This paper comprises the results of the quality of both underground water and atmosphere near Muassim Landfill”
