Which factor should be considered when selecting a pesticide storage site to prevent groundwater contamination?

• A. Soil and land surface characteristics.
• B. Building color.
• C. Distance from office.
• D. Proximity to parking.

Answer: (A)

Soil and land surface characteristics are the main factor to consider when selecting a pesticide storage site to prevent groundwater contamination. The soil type tells you how fast liquids can move through the ground: permeable soils let pesticides leach downward more quickly, while less permeable soils can trap or slow them down. The depth to groundwater matters because shallow groundwater can be reached by any spills or leaks sooner, and the slope or drainage of the land affects whether a spill will run off toward water sources or infiltrate downstream. Together, these factors determine how a storage site will either minimize or expose groundwater to a potential contaminant. Choices like building color, distance from the office, or proximity to parking don’t influence the risk of groundwater contamination.
