Which public health issue can arise from poor water quality?

Waterborne diseases are illnesses caused by pathogenic microorganisms that are transmitted through contaminated water. Poor water quality can lead to the presence of harmful bacteria, viruses, and parasites, which can enter the human body through drinking water, bathing, or even food prepared with contaminated water. Common examples of waterborne diseases include cholera, typhoid fever, and dysentery.

When water sources are polluted—whether through industrial runoff, agricultural chemicals, or improper waste disposal—the health risks associated with consuming or coming into contact with that water significantly increase. Thus, the link between poor water quality and waterborne diseases underscores the importance of maintaining clean water supplies to protect public health.
