Environmental engineering question :
A TCE plume is located in a 20 m-thick confined aquifer. Three wells were drilled as shown below (aerial view) and the head of the groundwater (meters above sea level) was measured in each well. The hydraulic conductivity of the aquifer is 50 m/d, the hydraulic gradient in the aquifer is 0.0028, and TCE has a retardation factor of 5 in this formation. a) Based on the map below, draw the direction the TCE plume will travel (arrow). b) If the TCE plume is moving at a velocity of 0.08 m/d, what is the porosity of the aquifer? Well 1 30.2 m Well 2 29.6 m pºl + W Well 3 30.0 m N E
