Which statement about pesticide storage facilities is true?

• A. Carefully consider soil and land surface characteristics when selecting a storage site to prevent potential contamination of water sources.
• B. Store pesticides only in metal buildings away from children.
• C. Use bright colored containers to indicate different pesticides.
• D. Keep all containers in traceable color-coded pallets.

Answer: (A)

Choosing where to store pesticides is about preventing water contamination. The best storage site is evaluated by how the soil and the land surface handle liquids. Soils vary in permeability—high-permeability soils (like sandy soils) can allow spills or leaks to quickly move toward groundwater, especially if the site is near wells, streams, or other water sources. A good storage location uses soils with lower permeability or has a containment approach that stops any leaked liquid from migrating. The land surface should also direct runoff away from water sources and away from areas that can carry contaminants into wells, rivers, or wetlands. In addition, the site should allow for secondary containment and have an impermeable base or other barriers to prevent seepage and runoff from reaching water bodies.

While building materials, security, or color-coding containers can be part of safe storage, they don’t address the main risk of spreading pesticides into water. Metal buildings or color-coded pallets alone don’t guarantee protection from environmental contamination; the critical factor is selecting a site with suitable soil and slope characteristics to minimize movement of chemicals toward water sources.
