- False
Show hintHide hint
Remember how scoring works.
Question 5.
A lake has various parameters measured: pH = 7.5, turbidity = 10 NTU, and microbial counts = 5 CFU. Discuss how you would approach calculating its WQI and the limitations of your assessment.
Show hintHide hint
Think about the weights associated with each measure.
Question 6.
Explain how external factors, like agricultural runoff, could affect the WQI of a river. What might the implications be for nearby communities?
