If private industry had been responsible and cleaned up the mess they created, EPA wouldn't have been in the position of trying to fix things.
Your rhetoric reminds me of the Black Lives Matter types, who blame the cop if he accidentally harms an innocent while pursuing a criminal, rather than saying the criminal is to blame.
Considering that the groundwater behind the plug the EPA removed, (with predicted results) had percolated through fractures in the rock from other mines in the area as well, I'm not sure how you can throw that back at the companies who had contained the problem. There were better ways to relieve that pressure, including drilling into the mine and pumping the water out, which would have alleviated the pressure and permitted the water to be treated to remove the metals.
THe EPA was in control, and they blew it, despite being told what the effects would be.
