What is a false statement concerning sewage and disease hazards?

The assertion that Entamoeba histolytica, hepatitis viruses, and Giardia cysts are easily destroyed by normal chlorination of sewage is the false statement because these pathogens exhibit varying degrees of resistance to chlorination. While chlorination is a common method for disinfecting water and sewage, it does not effectively eliminate all pathogens. Specifically, Giardia cysts can be particularly resilient and may require higher concentrations of chlorine or longer contact times to ensure their destruction. Additionally, certain strains of hepatitis viruses, particularly hepatitis A, can also demonstrate resistance.

Understanding the nuances of sewage treatment and pathogen susceptibility is crucial in managing public health risks associated with sewage. This knowledge informs practices surrounding sewage disposal, treatment, and the potential uses of treated sewage products, highlighting the importance of recognizing that not all pathogens can be controlled through conventional disinfection methods.
