The highly complex C IV systems observed in 0215 + 015 may have been formed by intervening rich clusters of galaxies, provided that systems of such complexity are not common, and that at early epochs, cluster galaxies of low luminosity possess metal-rich halos whose properties are broadly consistent with those of the Milky Way Galaxy. The question of the metallicity and the extent of dwarf galaxy gaseous halos, both in the field and in clusters, can only be addressed by means of Space Telescope observations. Emphasis is given to the detailed study of the characteristics of narrow absorption systems in QSOs exhibiting mass outflow, in order to establish whether or not these systems can be physically distinguished from other classes of QSO absorption lines, and whether they are unique to QSOs with broad absorption troughs.
