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.

Please answer the question in the picture and make sure you give the right answer!

Problem 1
In a small town with an area of 36 km² that relies solely on groundwater for its water supply, several
factors contribute to the water balance of the aquifer:
●
River Recharge: The river flowing through the town, with a flow rate of 16,000 m³/s, contributes
0.0001% of its water to recharge the aquifer.
● Upgradient Groundwater: Upgradient groundwater flows into the aquifer at a rate of 10 gallons
per minute (GPM).
Aquifer Discharge: The aquifer naturally discharges at a rate of 4 GPM.
Average Daily Demand: The average daily demand is 250 liters per capita per day.
●
Infiltration from Precipitation: With an average annual precipitation of 300 mm, 30% of which
infiltrates into the unconfined aquifer.
●
Given these parameters and neglecting other factors, such as evapotranspiration, determine the
maximum service population that can be sustained without causing a decrease in the water table.

Assume the described is at steady state. A fluid goes up to an aquifer that has groundwater and a chloride concentration of zero. The groundwater reservoir is 20,000 m^3 and has an outflow of 2 m^3/hour. If the fluid has a chloride concentration of 0.04 M and the aquifer outflow has 0.0084 M, how much chloride is precipitated in the reservoir? Any missing chloride is due to chemical reaction consumption.
