One‐dimensional analytical solutions for multispecies solute transport in a domain with two distinctive subdomains are developed based on exact interdomain boundary conditions. The derived solutions are tested through transient and steady state scenarios. In the global sensitivity analysis (SA) of the developed solutions, the influences of the up‐ and down‐gradient subdomains apportioned to the interfacial concentrations are 75.7 and 24.3%, respectively, while in the local SA, they are similar, at 65 and 35%, respectively. The overall SA results suggest that the common considerations of up‐ and down‐gradient influences are essential when the precision of the estimation is an important issue.
