6.6.2. Groundwater (Wells and Borewells)

Try these first

1. 1.

   What is groundwater?

   Hint

   Think about where water can be found underneath the Earth's surface.

2. 2.

   Why is it important to test groundwater?

   Hint

   Consider the potential impacts of impurities.

3. 3.

   What is a potential consequence of using groundwater with high chlorides in construction?

   • Increased strength of concrete
   • Corrosion of reinforcement
   • Enhanced workability

   Hint

   Think about how chemicals interact with metals.

4. 4.

   True or False: It is unnecessary to test groundwater if it looks clean.

   • True
   • False

   Hint

   Consider what impurities are invisible to the eye.

5. 5.

   A construction engineer is examining two sources of water: one from a well and the other from a river. Discuss how you would assess the suitability of each for concrete mixing.

   Hint

   Consider conducting both physical assessments and laboratory chem tests.

6. 6.

   A project failed due to poor water quality usage. Analyze the implications of using untested groundwater in construction.

   Hint

   Think about how various impurities can manifest in concrete over time.
