"The December 2008 ash spill at the Kingston Steam Plant was a catastrophic event of historical magnitude that continues to impact lives, property, and the environment. Data collected thus far have allowed us to conclude that the water supply is safe and other than the direct physical impacts, the ash has not led to acute toxicity in the Emory and Clinch rivers. Violations of Tennessee’s chemical water quality standards occurred immediately following the spill and whenever the ash has been resuspended by runoff or boat traffic. Chronic aquatic life effects and biomagnification of heavy metals in the food chain are possible and the monitoring of water, sediment, and fish tissue will need to continue."

A lot of information about runoff and erosion. Only a couple of references to heavy metals and none to any specific metals that I can find.
