What is an example of an environmental hazard?

Contaminated groundwater is indeed an example of an environmental hazard because it poses significant risks to both human health and the ecosystem. When groundwater becomes contaminated with hazardous substances—such as industrial chemicals, heavy metals, or pathogens—it can affect drinking water sources and agricultural irrigation, threatening the well-being of populations and the surrounding environment.

The presence of contaminants in groundwater can lead to long-term health issues for individuals who consume or come into contact with the polluted water. Moreover, once contaminated, groundwater is notoriously difficult and costly to remediate, making it a persistent and serious environmental concern.

In contrast, pristine forests, clean air, and natural landscapes are generally considered to be positive elements of the environment, contributing to ecological balance and human well-being rather than posing hazards.
