Chemical mixture modeling of Gaia and APOGEE stars indicates that most kinematic halo substructures are contaminated with Gaia-Sausage/Enceladus debris and heated disc stars, so no halo substructure is a chemically pure population.
RR Lyrae stars yield metallicity measurements for Milky Way halo substructures including Gaia Sausage/Enceladus at [Fe/H] = -1.57 dex, with some features like ED-1 showing disk contamination and others like Shiva and Shakti suggested as in-situ.
