True or False: Only improperly applied pesticides are likely to contaminate groundwater.

The statement that only improperly applied pesticides are likely to contaminate groundwater is false. While improper application can increase the risk of contamination, pesticides can leach into groundwater even when applied correctly under certain conditions. Factors such as the chemical properties of the pesticide, the soil type, rainfall, irrigation practices, and other environmental factors can contribute to the movement of pesticides into the groundwater.

Regardless of how carefully pesticides are applied, there is always a potential for contamination due to these varying factors. This underscores the importance of following best management practices and being aware of the environmental conditions to minimize the risk of groundwater contamination from pesticides, regardless of application method.
