Name one primary source of waterborne pathogens.

Name one primary source of waterborne pathogens.

• A. Industrial waste
• B. Pesticides
• C. Animal and human waste
• D. Chemicals from factories

Answer: (C)

The correct choice is based on the understanding that animal and human waste are significant contributors to the presence of waterborne pathogens. These pathogens, which include bacteria, viruses, and parasites, can enter water sources through the direct contamination of rivers, lakes, and groundwater. This contamination typically occurs when waste is not adequately treated or disposed of, allowing these microorganisms to proliferate. Animal waste, especially from livestock, can introduce pathogens such as E. coli and Salmonella into the environment. Similarly, untreated or poorly managed human waste can carry a variety of harmful agents, including cholera and hepatitis A. The presence of these pathogens in water supply systems can pose a serious public health risk. In contrast, while industrial waste, pesticides, and chemicals from factories can certainly contaminate water supplies, they generally do not introduce pathogens in the same direct manner as animal and human waste. Instead, these sources tend to contribute to chemical pollution or toxicity, rather than microbial contamination. Therefore, recognizing the role of human and animal waste is crucial for a water operator aiming to protect water quality and public health.
