Try these first

1. 1.

   What is a pumping test used for?

   Hint

   Think about measuring water levels.

2. 2.

   What do tracer tests track?

   Hint

   Consider what kind of substances can help track water.

3. 3.

   What is the primary purpose of a pumping test?

   • To measure the water quality
   • To measure drawdown and recovery
   • To identify pollutants

   Hint

   Think about what happens when a well is actively pumped.

4. 4.

   True or False: Tracer tests help us understand water flow paths in aquifers.

   • True
   • False

   Hint

   Consider what happens when you add a color to water.

5. 5.

   Consider a scenario where you conduct a pumping test and observe a rapid drawdown of water. What does this indicate about the aquifer's specific yield, and what steps would you take next?

   Hint

   Think about what rapid changes in water levels imply about the aquifer's condition.

6. 6.

   Design a tracer test to find out how quickly contaminants move through a local aquifer. What factors would influence the tracer type and monitoring approach?

   Hint

   Consider both the physical and chemical characteristics of the tracer.
