Ozone is an oxidizer - all it does is oxidize. For reference, chlorine bleach is an oxidizer. Most chemical contaminants will not be rendered safe by oxidizing. Many will not be removed by filtering (e.g. charcoal), either. If you suspect chemical contamination, you're better off looking for another water source.
