  1. Toxicity of fly ash depends how well the boilers burn the coal. Older boilers had higher“carbon in grits” so more unburnt nasties. However ash slurry is incredibly searching and quickly sets like concrete. Run off from coal mine drainage is many times worse and often a serious issue from disused mines.
