What should be removed from water to help reduce the presence of pathogens?

To help reduce the presence of pathogens in water, removing turbidity is essential. Turbidity refers to the cloudiness or haziness of a liquid caused by large numbers of particulates, which can include silt, clay, organic matter, and microorganisms. High turbidity levels can shield pathogens from disinfection processes, allowing them to survive and possibly lead to waterborne diseases.

When turbidity is reduced, it not only enhances the effectiveness of disinfection methods—such as chlorination—but also improves the overall quality of the water, making it clearer and more pleasant for consumption. By removing suspended particles, you increase the ability of disinfectants to effectively kill or inactivate pathogens in the water.

In contrast, while chlorine is a disinfectant used to eliminate pathogens, it is not something that should be removed to achieve this goal. Similarly, dirt and agricultural runoff, while contributors to water quality issues, do not specifically correlate with pathogen presence in the same direct way as turbidity. Therefore, focusing on turbidity removal is crucial in ensuring safe drinking water.
