Summary
was
created
using
only
a
listing
of
test
values.
The
original
study
procedure
and
raw
data
were
not
found.
However,
there
was
a
discrepancy`
noted
in
the
data
values.
Data
GO3703
was
reported
as
"mg/
L"
by
the
testing
laboratory,
but
was
entered
as
"mg/
kg"
values
in
the
3M
Environmental
Laboratory
archive
system
without
proper
conversion
from
volume
to
mass
units.
Therefore,
the
data
is
invalid
as
stated.
