What can toxic chemicals from waste disposal do?

Toxic chemicals from waste disposal can significantly contaminate drinking water supplies. When hazardous substances are improperly managed, they can leach into groundwater or surface water sources. This contamination poses serious health risks to humans and wildlife, as these toxicants can remain in the environment and affect water quality for extensive periods. Such pollutants can include heavy metals, pesticides, and industrial chemicals, all of which can enter the water supply and lead to a range of health problems, including cancers and developmental issues.

In contrast, the other options do not accurately reflect the impact of toxic waste. For instance, toxic chemicals do not improve agricultural production or enhance soil quality; instead, they can degrade soil health and harm crop yields. Similarly, rather than supporting aquatic life, toxic chemicals can severely disrupt ecosystems, leading to declines in fish populations and the overall health of aquatic habitats.
