GENERAL
SUBJECT
:
Copper
in
Wastewater
Discharges
from
the
Printing
and
Publishing
Industry
TOPICS
DISCUSSED
AND
ACTION
TAKEN
I
called
Mr
Tom
Estock
to
discuss
the
sources
of
copper
in
printing
and
publishing
wastewater
discharges.
Quad/
Graphics
Inc.
is
one
of
the
top
5
copper
dischargers
based
on
information
from
the
TRI
database.

Mr.
Estock
explained
that
copper
in
wastewater
discharges
comes
mainly
from
the
copper
and
chrome
plating
operation
in
the
gravure
printing
process.
De­
chroming
and
de­
coppering
is
performed
after
every
print
job,
and
then
the
cylinder
is
chrome­
and
copper­
plated
again
for
the
next
image.
He
also
informed
me
that
concentrations
of
copper
in
the
wastewater
are
measured
via
lab
analysis
of
actual
wastewater
samples.
