A chemical spill occurred at a gas station and a homeowner worried that the chemical could contaminate their well located at 100 feet away from the spill point. The hydraulic conductivity and the water table slope of the aquifer are 0.014 ft/sec and 1%, respectively. How long it takes the chemical to get the well? Assume the porosity is 20%.

Concept explainers

Groundwater Flow

The term groundwater refers to the water which is found beneath the earth's surface. Pores present in the soil and rocks with fractures make a passage for rainwater to enter the earth's surface and deposit as groundwater. The flow nature and direction of groundwater under the earth's surface directly impacts the strength and compressibility of the soil, which reflects its ability to support structural loads.

Question

A chemical spill occurred at a gas station and a homeowner worried that the chemical could
contaminate their well located at 100 feet away from the spill point. The hydraulic conductivity and
the water table slope of the aquifer are 0.014 ft/sec and 1%, respectively. How long it takes the
chemical to get the well? Assume the porosity is 20%.
