OK, time to put this kitty to bed...
I?m tired of the tone that some use in this thread. I won?t refute you directly, I?ll let the people whose job it is to educate people on the subject of ash do that. Please check out these websites and their links before you go yelling ?the sky?s falling?.

Like these, there are more out there. Just do some RESEARCH. Learn just a little about what you?re trying to talk about.
BTW, cadmium, arsenic and mercury are all found NATURALLY in soil, that?s DIRT for you and me. The same dirt kids all over the world play in. Yes, I know, dosage is the key, so find out the ppm/lbs that is IN the rockash, I?m sure it?s negligible.
The REAL contaminant is airborne dust particles, fine blown sand is an example of this. These affect your lungs just as it would living in the desert or near the beach. Try researching silicosis if you don?t mind.
In honor to the truth, the rockash you have is not from Pulverized Coal fired boilers (PC), it?s from Circulating Fluidized Bed boilers (CFB). It?s not as well suited for use in HPC, high performance concrete, as PC ash, but there are many beneficial uses for it, including use in ground repair work.
I believe the real crime Trans-Dominicana commited was not to have taken the measures in dust control and storing it so close to a body of water. People, it?s not poison.
Just my INFORMED two cents, E.
