In the Jeon Cheon Basin, unconsolidated alluvium and marine clay beds overlying Tertiary conglomerate and impermeable mudstone, and Cambro-Ordovician sedimentary rocks composed of mainly cavernous limestones, and age-unknowned crystalline rocks are occured. Most productive rock is Cambro-Ordovician limestones containing a lot of solution openings and secondary porosities and shows its transmissivity of 1836$m^2$/day and storativity of 1.47 $ imes$ $10^{-3}$. The storage of deep seated groundwater in linestone aquifer is estimated about 1059 $ imes$ $10^6$ metric tons, being equivalent to 6 years total precipitation of the basin. The safe yield of the groundwater to be abstracted from the aquifer is about 126,000 tons/day. To pump at least 100,000 tons/day of groundwater from the said aquifer, a well field comprising 34 deep wells ranging in depth from 80 to 100 meter and penetrating the cavernous limestone aquifer shall be established at middle and down stream area.
