Randomized trial evaluates how different water chemistries affect soil permeability, suggesting implications for geotechnical design.

This study aims to understand how different water chemistries influence the hydraulic properties of compacted clay-sand mixtures.
Conducted falling-head permeability tests using nine waters with distinct physicochemical characteristics.
Tested two sand-clay mixtures (70% clay-30% sand and 30% clay-70% sand) under uniform compaction energy.
Analyzed correlations between water chemistry attributes and hydraulic conductivity.
Saline and ion-rich waters resulted in higher hydraulic conductivity values than those measured with distilled water.
Very strong correlations were found between electrical conductivity, salinity, and ion concentrations with hydraulic conductivity (r2 = 0.89−0.98).
These increases in hydraulic conductivity are associated with changes in clay particle behavior under high ionic strength conditions.
