2. Water Quality Parameters

Try these first

1. 1.

   Define Total Dissolved Solids (TDS).

   Hint

   What does TDS measure?

2. 2.

   What does TSS stand for and what does it include?

   Hint

   Consider larger particles and microorganisms.

3. 3.

   What does TDS measure?

   • Total Decomposed Solids
   • Total Dissolved Solids
   • Total Disinfected Solids

   Hint

   Remember what TDS stands for.

4. 4.

   True or False: A higher BOD level means better water quality.

   • True
   • False

   Hint

   Consider the implications of high organic waste.

5. 5.

   You are given water samples from two rivers. River A has a TDS of 800 mg/L and River B has a TDS of 300 mg/L. Discuss the potential implications of these TDS levels on the ecosystems of both rivers.

   Hint

   Consider the sources of TDS in urban vs rural areas.

6. 6.

   A city's waste treatment plant reports COD levels of 500 mg/L and BOD levels of 200 mg/L in treated water. Analyze the efficiency and suggest what actions can be taken to improve it.

   Hint

   Think about methods to target non-biodegradable materials.
