The best way to keep tailings from polluting your world
The best way to keep pollution of tailings at bay, is to dig down 20 blocks below the last layer of the grass level, and clear out a room for a few stockpiles and some chests. Use one stockpile for tailings and the other for ores. Make sure the stockpile for the tailings is on the top of the list under “storage” tab in the Bloomery(or blast furnace) so the tailings will go to the tailing stockpile and nowhere else! You may need more than one stockpile for the tailings! They add up quick, especially if you are using the Bloomery!

I just put my tailings in carts and drop the carts into a pit. lot less space involved, but not as convenient as having a stockpile dedicated to them, maybe.
