6.1.4. Turbidity Meter

Try these first

1. 1.

   Define turbidity.

   Hint

   Think in terms of visibility in water.

2. 2.

   What does TSS stand for?

   Hint

   Consider what is measured in water quality testing.

3. 3.

   What is turbidity?

   • A measure of water's temperature
   • A measure of water's cloudiness
   • A technique for measuring pH

   Hint

   Think about visibility in water.

4. 4.

   True or False: Total Suspended Solids (TSS) can be determined accurately only if the sample volume is appropriately measured.

   • True
   • False

   Hint

   Reflect on why we need to measure enough water.

5. 5.

   Design an experiment to measure TSS in a river, considering varying flow rates. Discuss the challenges and how to address them.

   Hint

   Think about how water movement affects solids in a river.

6. 6.

   If a turbidity meter shows a reading of 0.2 NTU but the expected value is 5 NTU, what might you investigate?

   Hint

   Reflect on all potential sources of error in measurement.
