A draft

I 
regret to inform 
you'that 
Chapter

' 
[race 
metal 
analyses, one of l8 chapters in 
Part I 
and,a'critical section of the
'- 
''total

missing 
and will 
not

,, 
...S'bveral 
maJor:. 
breakdowns

experienced 
by

t{ood, 
our analytical 
chemist. 
In 
addition, 
the Illinois Geological

''-'[hs'had 
a

getting,to the 
ana]yses of coal,
' 
:s'1a9r 
and,fly ash

submitted from 
the 
Coffeen Generating

problems 
have resulted:in 
the 
projected 
six 
weeks delay in delivering the trace
metal 
chapter. 
In:Part

of 
the report, the benthic studies 
chapter by Gary
llarren has not

be 
forwarded 
to
