Q$2.$ The following data nme from a pumping test where a well wis pumpod at a rate of $200gpm.$ The geologist log of well is presented in Thble $2.$

A steel well cusing wre cemented$/$groathit to a depth of $182$ fi nod the pamping well was extended as an open boring prost that point. It was decided to observe druwdown varintion with time at obeervation aell locared $250$ ft suay from the pumping wrll$.$ The variation of drawdown at obeetrat of well with time is reported in Table $3.$

Preliminary questions befoce you do calculations: :

$($a$)$ Is aquifer cotilined or unconfinet $?$

$($b$)$ What rock unit$($s$)$ make up the aquifer $?$

$($c$)$ What is the saturated thicknest of the spttifer?

$($d$)$ Assuming no leakage und fully penetrating well; which mquifer test solutions are most applicable to this problem?
