1. the quality or degree to which a substance can be leached; the capacity of a material to have soluble components removed by percolating liquid.
Usage: technical; commonly used in environmental science, soil science, and materials engineering

Examples

• The leachability of heavy metals from contaminated soil is a major environmental concern.
• Engineers tested the leachability of minerals in the waste material before disposal.
• High leachability of nutrients from sandy soils means farmers must apply fertilizer more frequently.
• The leachability of salt from concrete affects its long-term durability in coastal regions.
• Researchers measured the leachability of pesticides to determine groundwater contamination risk.
