We study the hydrodynamic limit of a Brownian particle system in which drift acts on the leftmost particle. The limiting dynamics are described by a measure-theoretic parabolic free boundary problem. This extends earlier work in which, in special cases, the limit reduces to Stefan problems of melting solids or freezing supercooled liquids.
