Anyway, everything that was in the particular coal that was burned and did
not end up in the bottom ash or goes out the stack is a potential
contaminant in the "power plant gypsum". A friend who worked for Babcock
and Wilcox Nuclear said that if the dust from coal fired power plants was
treated by the same standards as Nuclear Plants, it would have to be
disposed of as a low level nuclear waste.
That being said, I would not dismiss it out of hand until we know the trace
elements composition and level is determined and more importantly the
inherent variability of those contaminants OVER TIME in the sludge. Coal
is inherently variable because it is the product of natural deposition.
You know this part was in a swamp backwater, while that part was in a
stream channel type of thing. Mike Miller
