Understanding Groundwater Flow

Why is it important to know the source of groundwater when drilling a well?

• To assess potential contamination risks

• To avoid drilling in rocky areas

• To ensure the well is deep enough

• To find the closest water source

What is the first step in determining the direction of groundwater flow?

• Measuring the depth of the aquifer

• Identifying the type of soil

• Mapping the surface water flow

• Choosing well locations and calculating water table elevations

How do you calculate the water table elevation?

• By adding the depth to water to the surface elevation

• By subtracting the depth to water from the surface elevation

• By measuring the distance between wells

• By using a GPS device

What is the significance of connecting water table elevation points in a triangle?

• To visualize the tilt of the water table and flow direction

• To determine the depth of the aquifer

• To identify the type of bedrock

• To calculate the volume of groundwater

Why is it important to understand the bedrock and geology when measuring groundwater flow?

• To find the most abundant water source

• To ensure the wells are evenly spaced

• To avoid drilling in areas with high water pressure

• To account for factors that might affect measurements
