What is the size range of Giardia cysts?

• A. 1 to 5 microns
• B. 5 to 10 microns
• C. 8 to 20 microns
• D. 20 to 30 microns

Answer: (C)

Giardia cysts typically range in size from 8 to 20 microns. This size range is significant for water operators and environmental health specialists as it helps in designing effective water treatment processes. Understanding the dimensions of Giardia cysts assists in selecting appropriate filtration methods for drinking water, as different filtration techniques are capable of removing particles of specific sizes. The cysts are too large to be effectively removed by standard disinfection methods such as chlorination alone, making it essential for water treatment facilities to ensure they use processes that address these specific pathogens. This knowledge contributes to ensuring safe drinking water and protecting public health.
