a contaminated spill at the location $(6,5),$ will travel along the regional groundwater hydraulic gradient within the saturated zone of the local unconfined aquifer. a local home, located at $(7,9),$ uses a home groundwater well. homeowners have hired you as their consultant, and would like scientifically accurate answers regarding the risk of contamination affecting their water supply. $($a$)$ calculate the distance when the plum is closest to the well.

A contaminant spill, at the location $(6,5),$ will travel along the regional

groundwater hydraulic gradient within the saturated zone of the local

unconfined aquifer. A local home, located at $(7,9),$ uses a home groundwater

well.

Homeowners have hired you as their consultant, and would like scientifically

accurate answers regarding the risk of contamination affecting their water

supply.

$($a$)$ Calculate the distance when the plume is closest to the well.

$($b$)$ From the time of occurrence of the spill, how long would it take for the plume

to be closest to the home?

Aquifer material porosity, $=0\mathrm{.}3$;$K=21\frac{m}{?}$ day

Show all your calculations and steps, including equipotential and flow line

equations, hydraulic gradient etc.
