What are waterborne pathogens?

Waterborne pathogens are characterized as microorganisms capable of causing diseases when they are transmitted through contaminated water sources. These pathogens typically include bacteria, viruses, and protozoa that can enter water supplies through various means such as sewage discharge, agricultural runoff, or poor sanitation practices. When individuals consume or come into contact with this contaminated water, they can experience a range of health issues, from mild gastrointestinal disturbances to severe illnesses.

This concept is crucial in water quality management and public health, as understanding the sources and types of waterborne pathogens helps in creating effective strategies for monitoring and treating water supplies to prevent outbreaks of disease.

The other options do not align with the definition of waterborne pathogens. Inorganic materials found in water sources refer to elements like metals and minerals, which do not cause diseases in the same manner. Organic nutrients, while beneficial for aquatic life, do not typically fall under the category of pathogens. Lastly, particles that improve water clarity may refer to certain substances that can help remove turbidity but are not related to disease causation.
