15.4.8.2.3. Common water constituents

Try these first

1. 1.

   What is salinity?

   Hint

   Think about how it affects aquatic life.

2. 2.

   What does hardness measure in water?

   Hint

   Relate it to soap effectiveness.

3. 3.

   What is the primary constituent affecting aquatic life?

   • Salinity
   • Hardness
   • Temperature

   Hint

   Remember the role of salt in ecosystems.

4. 4.

   True or False: High hardness levels can improve soap effectiveness.

   • True
   • False

   Hint

   Think about cleaning with hard water.

5. 5.

   Investigate the impact of salinity on a specific aquatic species and propose practical solutions for managing salinity levels in their habitat.

   Hint

   Research real-life case studies where salinity impacts were identified.

6. 6.

   Conduct a comparative analysis of areas with high water hardness versus low hardness in terms of their water system infrastructure costs.

   Hint

   Look into maintenance records or reports from public works.
