  We present results of an exploratory study of singlet scalar states in
unquenched QCD using both glueball and meson operators. Results for non-singlet
non-strange scalar mesons are also presented. We use Asqtad improved staggered
fermions and gauge configurations generated by the MILC collaboration at
lattice spacings of .12 and .09 fm. In this formulation, the glueball mass is
not significantly different from the quenched value at finite lattice spacing.
Significant taste violations are present in the scalar sector. At light quark
masses, decay channels complicate the mass determinations. There is some
evidence that the non-strange singlet meson lies below the non-singlet meson.
