Which statement about pesticide storage facilities is true?

The statement that storage facilities must consider soil and land surface characteristics is true because these factors play a crucial role in environmental safety and potential contamination risks. Understanding the characteristics of the soil and land surface is essential to prevent pesticide runoff and leaching into groundwater or nearby bodies of water. Proper site selection for storage facilities involves assessing factors such as drainage patterns, permeability of the soil, and proximity to water sources. These considerations help ensure that any potential spills or leaks do not adversely affect the surrounding environment.

In contrast, focusing solely on temperature control does not encompass all necessary aspects of safe pesticide storage, as other factors like humidity, ventilation, and structural integrity are also critical. Storing pesticides only outdoors can expose them to the elements and increase the risk of spills or contamination. Lastly, while having a dry and ventilated space is important, it is not sufficient to deem any such space as suitable for storage; more comprehensive criteria and safety measures must be followed to protect both the pesticides and the environment.
