I used to own a house that was built on a stemwall foundation. I
grounded the electric outlets by drilling a hole up through the bottom

I'm now buying a house that is built on a slab, and many of the
outlets are ungrounded. How should I deal with the problem in this
case?

Eh? What problem?

Trying to ground wall outlets in a hiuse with a slab foundation rather
than joists bearing on a concrete stemwall. The latter allows running a
ground wire up to the wall outlet from the basement or crawl space.
Can't do that with a slab foundation.

Clarification: Why does the OP choose to see ungrounded outlets as a
*problem?*
