The correct answer is: Negative impact on drinking water quality

The primary detrimental effect of water pollution is its negative impact on drinking water quality. Water pollution introduces harmful substances into water bodies, which can contaminate sources of drinking water. This contamination can arise from various pollutants, including chemicals, heavy metals, pathogens, and organic materials that compromise the safety and quality of water. As a direct consequence, populations can face health risks from consuming polluted water, potentially leading to illnesses and various health issues. Moreover, the impact on drinking water quality is significant because it not only affects public health but also has broader implications for communities, such as increased treatment costs and the necessity for alternative water sources. Ensuring safe drinking water is a fundamental public health priority, highlighting the importance of addressing water pollution effectively to protect health and well-being.
