Question $5$

A landfill has started leaching TCE into the groundwater. A drinking water well is

located $5$ miles down gradient and there is some concern over TCE

contamination in the well.

The aquifer has the following properties:

$f$@$c=0\mathrm{.}01$

porosity $=0\mathrm{.}39$

bulk density $=2\mathrm{.}60k\frac{g}{L}$

groundwater velocity $=0\mathrm{.}4\frac{m}{?}$ day

TCE has an oral slope factor of $0\mathrm{.}0061$ kg day $\frac{?}{mg}.$

What is the velocity of the TCE in the aquifer?

$0\mathrm{.}89\frac{m}{d}$

$2\mathrm{.}56\frac{m}{d}$

$1\mathrm{.}54\frac{m}{d}$

$1\mathrm{.}02\frac{m}{d}$
