3Question 3.
What is the primary purpose of evaluating BOD in water testing?
- To measure the chemical composition
- To assess the level of organic pollution
- To determine the physical properties
Show hintHide hint
Think about what BOD indicates regarding water quality.
4Question 4.
True or False: The temperature during BOD testing should be the same as the surrounding environment.
- True
- False
Show hintHide hint
What is the standard practice for temperature control?
Question 5.
Consider a water sample where the initial dissolved oxygen is 8 mg/L, and after 5 days, it is 1 mg/L. Calculate the BOD and explain whether it indicates clean or polluted water.
Show hintHide hint
Remember, higher BOD indicates more organic matter.
Question 6.
If you were to perform BOD testing in different geographical locations with varying temperatures, how would you standardize your results for consistency?
Show hintHide hint
Think about why temperature is crucial in microbial activity.
