Description
Director of Water and Pollution Control, John Dunn, discusses the Safety of Ames drinking water.
A
A
A
A
B
What
what
happened
was
that
Flint
had
changed
its
treatment
system
and
the
chemistry
of
the
water
going
out
into
the
system
changed
and
it
became
aggressive
and
corrosive,
and
what
happened
is
that
when
that
aggressive
water
entered
a
customer's
coming
actually
the
plumbing
in
their
house,
when
that
plumbing
was
made
of
lead,
it
actually
started
to
corrode
the
lead
and
contaminate
the
water
with
really
really
unsafe
levels
of
lead.
And
what.
A
B
That's
right,
the
they
switched
and
started
using
water
from
the
Flint
River,
which
did
not
have
lead
in
it,
and
the
water
coming
from
their
treatment
plant
didn't
have
led
in
it.
The
problem
was
that
the
water
was
corrosive,
and
so,
when
it
entered
the
customers
home,
it
had
the
ability
to
leach
led
out
of
the
customer's
home
plumbing
the.
A
Press
conference
you
had
recently
was
really
good
news
in
so
many
different
ways.
One
we
have
responsible,
reliable,
dependable
professionals
who
follow
all
the
federal
regulations
and
state
regulations
and
I,
don't
even
know
how
many
regulations
for
testing
water,
but
also
you
look
at
the
infrastructure,
and
there
were
some
good
news
there,
too,
yeah.
B
We
took
a
look
at
just
how
many
properties
and
aims
we
thought
still
had
lead
service
lines.
Lead
was
actually
very
common
in
the
1920s
30s
40s,
but
as
we
as
we
looked
through,
those
many
of
those
service
lines
had
been
replaced
over
the
years,
and
so
now
it
looks
like
out
of
about
19,000
individual
properties
for
individual
service
lines
that
there's
maybe
just
a
little
over
300
that
still
have
lead
service
lines.
So
that
means
for
about
ninety
eight
plus
percent
of
our
customers.
It's
really
not
an
issue
at
all.
B
A
B
A
A
B
That
it
makes
the
water
more
stable
it.
Actually
it's
in
a
category
that
is
typically
described
as
being
slightly
depositing
and
there's
two
advantages.
First,
the
water
being
non
aggressive
towards
the
lead
means
that
it's
not
likely
to
cause
led
to
leach
out
and
then
the
fact
that
it's
slightly
depositing
means
that
is,
it
puts
that
slight
ring
of
deposits
on
the
inside
of
the
pipe.
It
actually
forms
a
physical
barrier
that
separates
the
water
from
the
pipe
materials,
and
so
it
provides
a
separate
barrier.
The.
A
B
Do
and
the
reason
we
do,
that
is
because
disturbing
a
lead
service
line
and
not
completely
removing
it,
can
actually
make
the
lead
concentrations
much
much
worse.
So
is
we're
going
down
a
street
if
we're
replacing
a
water
main
and
we
find
a
lead
service
attached
to
it.
We
will
actually
replace
that
for
free
as
a
part
of
our
construction
project
for
the
homeowner,
and
so.
B
That's
correct
when,
when
the
lead
and
copper
rule
was
passed
by
the
EPA
in
1991,
we
did
an
initial
survey
of
the
community
and
there
was
roughly
1,500
properties
at
that
time.
That
had
lead
service
lines
and
so
now
the
fact
25
years
later,
that
we're
down
to
just
three
hundred
shows
that
we
are
making
progress
on
getting
those
out
of
the
ground.
Those.
A
B
B
First,
we
were
going
to
have
by
about
the
middle
of
next
next
week
or
around
May
twenty-fifth,
an
interactive
map,
our
website,
so
customers
can
go,
they
can
type
in
their
address
and
it
will
tell
them
whether
their
property
is
on
our
list
of
suspected
lead
service
lines
or
they
can
just
navigate
the
map
zoom
in
on
their
neighborhood
and
find
their
house
until
that
way.
But
we
don't
want
to
have
to
make
19,000
customers
all
go.
B
Look
at
the
website,
so
we
are
going
to
mail
starting
on
May,
twenty-fifth
letters,
individual
letters
to
each
of
those
three
hundred
or
so
properties
that
our
records
indicate.
They
have
lead
service
lines
and
those
letters
will
first
make
them
aware
that
they
have
a
lead
service
line.
It
will
also
include
a
brochure.
That's
got
some
really
simple
tips
that
they
can
use
to
protect
themselves
and
then
also
included
in
the
letter
will
be
an
offer
for
us
to
test
the
water
in
their
home
for
free
for
them.
B
So
any
customer
who
has
a
lead
service
line.
We
would
give
them
a
sample
kit
and
instructions
on
how
to
collect
a
sample,
and
they
could
do
it
and
bring
it
back
to
us
and
we
would
test
it
in
our
state
certified
lab,
and
then
we
would
provide
an
individualized
report
back
to
them.
That
doesn't
just
give
them
a
number,
but
we
help
them
put
that
number
into
context
as
to
whether
it's
a
good
result
or
perhaps
not
so.
A
B
That
is
absolutely
true,
even
in
Flint
the
lead
service
lines
that
were
there
have
been
in
the
ground
for
decades
without
without
posing
a
problem
until
the
water
became
aggressive
and
so
in
ames
those
lead
service
lines
have
been
in
place.
The
oldest
one
in
our
records
dates
back
to
the
1890s.
There's
a
lead
service
line,
that's
that
old
in
our
community.
It
hasn't
posed
a
problem
for
all
these
years.
B
A
B
We
have
portions
of
the
the
web
page
and
you
can
get
to
it
just
by
using
the
the
short
URL
city
of
ames,
org,
slash,
lead
and
that'll.
Take
you
where
you
can
find
that
interactive
map,
as
well
as
a
lot
of
information,
a
lot
of
definitions
of
some
of
the
technical
terms
that
you
might
find.
If
you
looked
on
a
regulatory
website,
we're
also
going
to
be
doing
a
number
of
social
media
posts
over
the
next
couple
of
weeks.
B
A
A
If
you'd,
like
more
information
about
lead
in
the
water,
in
the
absence
of
lead
in
the
city
of
ames
water,
get
all
the
information
about
that
at
city
of
ames
org
forward,
slash,
lead,
you'll,
get
all
sorts
of
access
to
the
interactive,
interactive
map
and
information
about
what
you
can
do
to
protect
your
safety.
Some
more
things
to
think
about
is
we
get
into
the
month
of
may
remember.
The
ferment
aquatic
center
will
be
opening
opening
day
is
Saturday.
