In environmental engineering, groundwater remediation is a crucial process for cleaning

up contaminated groundwater. One common remediation technique is pump$-$and$-$treat,

where groundwater is pumped out of the subsurface, treated to remove contaminants, and

then re$-$injected back into the ground. Suppose you are tasked with designing a pump$-$and$-$

treat system for a contaminated groundwater site. The goal is to determine the optimal

pumping rate $(Q)$ that maximizes the removal of contaminants from the groundwater over

a certain period of time.

What is the pumping rate $(Q)$ that achieves a contaminant concentration of $C_{-}$target $=$

$0\mathrm{.}15m\frac{g}{L}$ within a time period of $t=8$ days.

Assume that the contaminant concentration in the groundwater is described by the

following equation:

$C=0\mathrm{.}5**\frac{Q^2+Q-2}{t^2+t+0\mathrm{.}1}$

$f(t,Q)={?}_{(}(){)}_t$arget

Tolerance $=0\mathrm{.}001$
