2. Microorganism Standards

Try these first

1. 1.

   What is the maximum number of microorganisms allowed per 100 ml in water according to CPCB standards?

   Hint

   Think of the value the CPCB set for water quality.

2. 2.

   What does CFU stand for?

   Hint

   Focus on what we call a measure of viable microbes.

3. 3.

   What is the standard limit for microorganisms in drinking water according to CPCB?

   • 1 per 100 ml
   • 5 per 100 ml
   • 10 per 100 ml

   Hint

   Consider the safe drinking water standards.

4. 4.

   The method of counting microorganisms by culture relies on their ability to grow and reproduce. True or False?

   • True
   • False

   Hint

   Remember what viability means!

5. 5.

   Propose a strategy for accurately measuring microorganisms in a sample known to have a high concentration of pathogens.

   Hint

   Think about how you would reduce the number to manageable levels.

6. 6.

   Evaluate the effectiveness of visual indicators like turbidity in assessing water quality against proven laboratory methods.

   Hint

   Consider the pros and cons of quick tests vs. laboratory confirmations.
