The only way to not concentrate it is to let it go up the stacks. That has other problems beyond the heavy metals, most significantly is acid rain. I believe the issue is still about location...east of the mississippi I am a fan of piping the fly ash back to room and pillar mines as a slurry and using it to fill closed off sections of mines. This would have other benefits as well...most closed off sections of mines are still empty spaces that have simply been walled off. Methane can build up in these areas and is an explosive hazard (this is what happened at the Sago Mine in WV. The methane in a closed off section was ignited by a lightning strike that traveled through the ground). If the space is filled rather than closed off, no methane build-up. Perhaps a bit economically challenging, but think of the cost of the TVA spill and the lawsuits from the Sago Mine and the costs start to be offset. West of the Mississipi you have a lot more strip mines and it would be pretty easy to use the fly ash as fill during the reclamation process.
