Microorganisms commonly found in wastewater include which of the following?

The selection of bacteria, viruses, protozoa, and helminths as common microorganisms found in wastewater is particularly accurate because each of these categories plays a significant role in the microbial ecology of wastewater treatment systems.

Bacteria are the predominant microorganisms in wastewater, responsible for breaking down organic matter through various metabolic processes. They play a crucial role in the biological treatment of wastewater, aiding in the decomposition of organic pollutants.

Viruses, while much smaller than bacteria, are also present in wastewater and can affect both humans and animals. Their presence poses health risks and may contribute to the infectious disease potential of untreated wastewater.

Protozoa are single-celled microorganisms that feed on bacteria and organic particles in wastewater. Their role in maintaining microbial balance is essential, as they help control bacterial populations and enhance the overall treatment process.

Helminths, which include parasitic worms, may also be found in wastewater, particularly in untreated sewage. Their presence is a concern due to potential health risks associated with transmission to humans and animals.

The inclusion of these four groups highlights the complexity of microbial life in wastewater and underscores the need for effective treatment processes to manage their presence and reduce health risks. Other options may include microorganisms or entities not typically found in wastewater or include irrelevant components,
