Question

1. What is the hydraulic gradient between points A and B.

2. What is the minimum elevation of the waste cell.

3. Estimate the travel time for contaminants to reach point A if the protective liner of the landfill cell fails and contaminated liquid seeps into the groundwater.

Two boreholes are located at points A and B along the same flowline. The soil between them has a hydraulic conductivity of 3.0 space cross times 10 to the power of
negative 5 end exponent feet per second and a porosity of 40%. Water flows from B to A in the water table aquifer. A 500 X 100 foot landfill cell is planned to be built
between points A and B as shown. The bottom of the landfill cell must be at least 5 feet above the water table at all points.

Expert Solution

Step 1 Given data

$K = 3 \times 10^{- 5} ft / \sec n = 40 % Landfill cell - 500 \times 100 ft$

To determine-

1. What is the hydraulic gradient between points A and B.

2. What is the minimum elevation of the waste cell.

3. Estimate the travel time for contaminants to reach point A if the protective liner of the landfill cell fails and contaminated liquid seeps into the groundwater.
