How do insecticides affect the environment?
How do herbicides affect the environment?
Herbicides can contaminate groundwater and surface water. Spray drift and volatilization of herbicides can transport the chemical into the atmosphere during and after application, potentially allowing herbicides to reach surface water and groundwater via precipitation.
