If a relatively thin impervious formation of a stiff clay layer is encountered at a shallow depth underlain by an extensive thick confined alluvial aquifer, then it is an excellent location for a cavity well. A hole is drilled using the hand boring set, and casing pipe is lowered to rest firmly on the stiff clay layer, Fig. 5.54. A [...]
