I'm an environmental engineer. Coal ash can contain PAHs (polynuclear aromatic hydrocarbons) along with the heavy metals and acidic conditions. The risk to human health from PAHs is primarily ingestion (ie, such as kids breathing in dust, etc).
The solution...bury it with about 2 feet of clean soil and leave it buried. Also, keep it away from your wells and definitely do not bury it in your garden areas.
Hope this helps,
Dan
