What is a potential impact of pesticide residues in drinking water?

The presence of pesticide residues in drinking water can pose significant health risks to humans. Pesticides are chemical substances used to kill or control pests, but when these chemicals contaminate drinking water, they can lead to a range of adverse health effects. These may include acute symptoms such as nausea and dizziness, as well as chronic issues such as endocrine disruption or increased cancer risk, depending on the type and concentration of pesticide involved.

Understanding the potential health risks associated with pesticide residues is crucial for public safety and health policy. While higher water clarity, increased aquatic life, and lower treatment costs may seem beneficial, these outcomes are not typically associated with the presence of pesticide residues. In fact, pesticides often harm aquatic ecosystems and necessitate more rigorous treatment processes, which could lead to increased costs, making health impact the central concern in this scenario.
