What potential effect can result from improper pesticide application near water sources?

Improper pesticide application near water sources can lead to environmental contamination and significant harm to aquatic life. Pesticides may run off into these water bodies, affecting the water quality and harming organisms that rely on aquatic ecosystems. This can result in a wide range of detrimental effects, including toxicity to fish and other wildlife, disruption of habitat, and even ecological imbalances. The application of pesticides in close proximity to water sources necessitates strict adherence to safety guidelines to protect both the environment and human health. This is a critical consideration in pest management strategies to ensure that pesticide use does not inadvertently contribute to the decline of biodiversity or the degradation of natural habitats.
