Hi Lisa,
You could try a calorific value test, coal fines would obviously give
the sample a higher value that expected. I have recently had a GI for
one of our old collieries with this test in - although here it was to
discuss the potential for spontaneous combustion within the spoil heap!
Even if the material is Iron Silicate, does this pose a significant risk
of significant harm? I doubt it. Therefore if I were you, I would be
questioning the grounds for my involvement!
Hope that helps,
Mark

Hello all
Quick background, we have a complainant who insists that refurbishment
work
of a viaduct has led to pollution of the surrounding land (his words)
and
was insistent that the iron silicate shot used to remove paint is still
on
site in significant amounts. The site was cleaned during works adhering
to
best practicable means and again at the completion of works, which as a
result of the complainant included a scrape of surface material
replacement of topsoil in some areas.
2 years down the line from the original complaint the complainant is
still
insistent that there is an issue and despite numerous meeting on site
with
other parties involved has made very clear his complete "lack of faith
in
the council". A recent site visit with senior management and the
complainant still has not resolved this.
Now to the muppet question, having a site investigation (both labs and
GI)
and consultancy background before moving to local authority (plus the
necessary post graduate degree) i am very confidant that the material
the
complainant is referring to is infact coal fines within the glacial
till,
however the complainant is unwilling to acknowledge the councils
technical
ability to reach this conclusion.
Therefore I need a test that could prove that the material in question
is
in fact coal fines and not iron silicate. I was thinking along the
lines
of a float sink test so any confirmation of this or any alteratives
would
be greatly appreciated. (its been over 10 years since i last carried
out
this test so I'm a bit woolly as to what it entails).
Yours in anticipation
Lisa
