“…Based on the thickness, hydraulic features, water quality and the category of the aquifer other aquifer units become exposed. In this regard, individual farmers can meet their water needs for small-scale farming practices where they can drill wells that range from 100 to 150 m in depth in order to tap the various underground resources (Madani et al, 2019). Overall, there are eight principal (Neogene, Damman, UmmeErRadhuma, Riyadh and Wasia, Minjur and Daruma, Tabuk, Wajid and Saq) and nine secondary (Wadi sediments, Basalts, Aruma, Lower cretaceous, Sakaka, Upper Jurassic, Al-Jilh, Al-Khuf and Al-Jouf) aquifers or groups of aquifer are found in KSA (Zaidi et al, 2015).…”
