Why is it important to monitor fecal coliform in biosolids?

Monitoring fecal coliform in biosolids is crucial for preventing pathogens in the environment. Fecal coliform bacteria are indicators of potential contamination by fecal matter, which may contain harmful pathogens such as viruses, parasites, and bacteria that can pose health risks to humans and animals. By regularly testing for these bacteria, wastewater treatment facilities can assess the degree of pathogen exposure and ensure that biosolids being land-applied or disposed of are safe for the environment and public health.

If fecal coliform levels are too high, it indicates a potential risk for spreading disease, particularly if the biosolids are used in agricultural practices or near populated areas. Proper monitoring and management of fecal coliform levels help in applying regulations and best management practices to mitigate these risks, promoting safety in land use and preventing contamination of water sources or the surrounding ecosystem.

Understanding this aspect is vital in the role of a wastewater operator, as it supports the protection of public health and environmental integrity.
