Question
In a contaminated site, three monitoring wells (into the unconfined aquifer) have been
developed. The east well (surface elevation: 254 m) measures a water level 30 m below the
surface. The west well (surface elevation: 279 m) measures a water level 24 m below the surface.
The south well (surface elevation: 266 m) measures a water level 41 m below the surface. Please
plot the direction of the groundwater flow, and calculate the contaminant's velocity if the
aquifer's hydraulic conductivity is 6 x 103 m/s and the porosity is 0.4.
