The Leederville Aquifer is a significant freshwater aquifer located in the south west of Western Australia and predominantly beneath the Swan Coastal Plain west of the Darling Scarp. It is located above the Yarragadee Aquifer, and beneath two superficial aquifers known as the Gnangara Mound and Jandakot Mound. These aquifers are separated by impervious layers with no groundwater called aquitards. 〔(【引用サイトリンク】 title=Groundwater )〕〔 Leyland, Lucy Ann (2011) Hydrogeology of the Leederville Aquifer, Central Perth Basin, Western Australia.

Water extracted from this aquifer is used in Perth's water supply. It is ultimately replenished by rainwater, however in recent years the state government has supplemented this by also pumping treated wastewater into the aquifer. ==See Also== *Yarragadee Aquifer *Climate of Perth ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Leederville Aquifer」の詳細全文を読む スポンサード リンク
