That’s a little more difficult. I think the first step is to identify the specific compounds you are trying to remove. Volatility becomes relevant here.

Yeah this is why I'm leaning towards RO just as a overkill catch all type of system.
It may just be best to research a bottled drinking/cooking water solution in your area and use municipal for everything else. That’s what we do even though RO would make our water better it really depends on molecule size. If the contaminant has a smaller molecule size than H2O it’s coming through. Sodium fluoride for example disassociates to F- and NA+ in aqueous solution. Both molecules smaller than H2O.
Good info thank you. I will look into that.
