Electron - impurity scattering in the crust of neutron stars may be a relevant mechanism in delaying the cooling and in enhancing the decay of the pulsar's magnetic field. Extending previous work, in the present note I investigate the physics of the interfaces between layers in the crust of an isolated neutron star. The calculations confirm the possible presence of high impurity concentrations and thus imply a decrease of the transport properties at low temperature.
