Pretty sure that while lava is hot it is not all that hot compared to a proper incinerator. Add to that the total lack of control over the combustion and you would get a miserable smokey mess of partly combusted pollutants burned just enough that whatever toxic crap doesn't leave as smoke will easily leach out into the water.
Worst. Idea. Ever.
