Chlorine is primarily used in water treatment to disinfect and kill harmful microorganisms, including bacteria and viruses. In the context of Fecal Coliform sampling, the correct role of chlorine is that it can interfere with the results.

When chlorine is present in water samples, it can affect the viability of the Fecal Coliform organisms that are being tested. This interference can lead to inaccurate readings in the sampling process, as the chlorine can kill the very organisms that are being measured. As a result, understanding the impact of chlorine is crucial for obtaining valid test results in Fecal Coliform sampling.

This highlights why proper sample handling is critical, particularly ensuring that chlorine levels are minimized or managed effectively so that the sampling accurately reflects the microbial populations present in the wastewater being tested.
