00:00:04:14 - 00:00:07:14
Actionable foresight.

00:00:07:20 - 00:00:09:13
Most organizations approach

00:00:09:15 - 00:00:11:10
PFAS as a technical problem.

00:00:11:11 - 00:00:13:20
Test it, treat it remediated.

00:00:13:20 - 00:00:15:08
But for the communities

00:00:15:08 - 00:00:16:19
living with it, PFAS

00:00:16:19 - 00:00:18:14
is something else entirely.

00:00:18:15 - 00:00:19:11
It's uncertainty,

00:00:19:11 - 00:00:21:06
and sometimes it's anxiety.

00:00:21:08 - 00:00:22:18
Welcome to Nexus Podcasts.

00:00:22:18 - 00:00:23:16
I'm Ben Hall,

00:00:23:17 - 00:00:25:05
global thought leadership manager

00:00:25:05 - 00:00:26:03
at GHD.

00:00:26:05 - 00:00:28:19
Today I'm joined by Sharon Sebastian,

00:00:28:20 - 00:00:29:23
executive advisor

00:00:29:23 - 00:00:31:19
and business advisory at GHD,

00:00:31:19 - 00:00:32:14
to explore

00:00:32:14 - 00:00:33:10
why PFAS

00:00:33:10 - 00:00:35:11
community engagement is no longer

00:00:35:11 - 00:00:37:00
just about communication.

00:00:37:00 - 00:00:38:12
It's all about trust,

00:00:38:13 - 00:00:40:13
social license and leadership.

00:00:40:14 - 00:00:42:14
Sharon, Thank you Ben.

00:00:42:14 - 00:00:43:21
Really looking forward

00:00:43:21 - 00:00:44:19
to having a conversation

00:00:44:19 - 00:00:46:10
with you about this topic.

00:00:46:12 - 00:00:47:12
So let's kick it off

00:00:47:12 - 00:00:49:03
with a big broad question.

00:00:49:03 - 00:00:51:04
Firstly, just give us an overview of

00:00:51:04 - 00:00:52:08
what actually is

00:00:52:08 - 00:00:53:12
for those who don't know, even

00:00:53:12 - 00:00:55:00
though it's quite a well-known topic.

00:00:55:00 - 00:00:58:02
And also secondly, just explain why

00:00:58:09 - 00:00:59:04
PFAS engagement

00:00:59:04 - 00:01:00:12
is so much different

00:01:00:12 - 00:01:01:13
to other traditional

00:01:01:13 - 00:01:03:07
stakeholder engagement.

00:01:03:09 - 00:01:04:18
two very good questions, Ben.

00:01:04:18 - 00:01:08:08
And per and polyfluoroalkyl

00:01:08:10 - 00:01:10:07
substances, otherwise known

00:01:10:07 - 00:01:12:15
very commonly as PFAS.

00:01:12:17 - 00:01:13:15
You'd be surprised

00:01:13:15 - 00:01:16:02
you'd find these small amounts

00:01:16:02 - 00:01:19:12
in your nonstick pants, your shampoos,

00:01:19:14 - 00:01:20:14
your soaps.

00:01:20:14 - 00:01:23:11
So it's a pretty common chemical.

00:01:23:13 - 00:01:26:13
However, where we've started to see

00:01:26:13 - 00:01:28:03
it'd be quite prevalent

00:01:28:03 - 00:01:28:19
and require

00:01:28:19 - 00:01:30:05
remediation is where

00:01:30:05 - 00:01:31:07
we've actually founded

00:01:31:07 - 00:01:33:03
in firefighting font

00:01:33:04 - 00:01:35:11
that historically was used

00:01:35:11 - 00:01:38:15
and has now since being phased out.

00:01:38:21 - 00:01:41:12
So what happens with PFAS

00:01:41:14 - 00:01:43:09
it seeps into the groundwater

00:01:43:11 - 00:01:44:17
you can't get rid of it.

00:01:44:17 - 00:01:48:12
So it's a pretty stubborn chemical and

00:01:48:14 - 00:01:49:17
there's quite a lot of work

00:01:49:17 - 00:01:50:11
that's happening,

00:01:50:11 - 00:01:53:18
I will say globally to actually address

00:01:53:20 - 00:01:55:14
and remediate PFAS

00:01:55:14 - 00:01:57:19
historically at different sites

00:01:57:19 - 00:01:59:13
where it's been used across

00:01:59:13 - 00:02:01:05
different sectors, primarily

00:02:01:06 - 00:02:02:07
firefighting foam,

00:02:02:07 - 00:02:03:13
I would say

00:02:03:15 - 00:02:05:11
has been the most common issue.

00:02:05:13 - 00:02:07:01
to your second question

00:02:07:01 - 00:02:08:21
about why it's so different.

00:02:08:21 - 00:02:10:03
I would go to

00:02:11:16 - 00:02:12:22
it is an unknown.

00:02:12:22 - 00:02:14:10
It's a new contaminant

00:02:14:12 - 00:02:15:10
You could say it's

00:02:15:10 - 00:02:16:21
an emerging contaminant.

00:02:16:21 - 00:02:18:10
Even though we've known about it

00:02:18:10 - 00:02:19:02
for a little while,

00:02:19:03 - 00:02:20:11
it's still learning more

00:02:20:11 - 00:02:21:05
and new

00:02:21:07 - 00:02:22:10
as the science

00:02:22:11 - 00:02:24:23
gets more robust as well.

00:02:25:01 - 00:02:26:20
And for community,

00:02:26:20 - 00:02:28:15
it can cause uncertainty

00:02:28:16 - 00:02:29:01
and a little

00:02:29:02 - 00:02:30:20
bit of anxiety in a way,

00:02:30:20 - 00:02:32:20
because of those unknowns.

00:02:32:20 - 00:02:33:13
The main thing

00:02:33:13 - 00:02:34:11
I would say around

00:02:34:11 - 00:02:36:08
that uncertainty is with

00:02:36:08 - 00:02:39:13
the groundwater kids may be affected.

00:02:40:21 - 00:02:42:17
Not having those clear time

00:02:42:18 - 00:02:44:14
frames around

00:02:44:14 - 00:02:46:21
when this emerging contaminant

00:02:46:21 - 00:02:47:18
can actually be

00:02:47:19 - 00:02:49:00
remediated

00:02:49:01 - 00:02:52:01
on different projects can cause issues.

00:02:52:05 - 00:02:53:17
So it's all young knowns

00:02:53:19 - 00:02:55:09
is what sort of courses concern

00:02:55:09 - 00:02:57:06
for people and communities basically

00:02:57:07 - 00:02:59:11
who are surrounded by this.

00:02:59:13 - 00:03:00:11
It is because you're

00:03:00:11 - 00:03:02:07
not just explaining data

00:03:02:07 - 00:03:04:04
when it comes to PFAS.

00:03:04:06 - 00:03:05:11
You're dealing with something

00:03:05:11 - 00:03:06:20
that it's not tangible.

00:03:06:20 - 00:03:07:22
You can't see it.

00:03:07:22 - 00:03:10:08
And because it's so persistent

00:03:10:08 - 00:03:12:21
in some communities or some areas

00:03:12:21 - 00:03:15:07
where contamination may have occurred,

00:03:15:09 - 00:03:17:13
it can be quite deeply personal

00:03:17:13 - 00:03:19:05
for the individuals and communities

00:03:19:05 - 00:03:20:12
who are actually having to

00:03:20:13 - 00:03:21:15
deal with it.

00:03:21:15 - 00:03:22:23
So it's something

00:03:23:00 - 00:03:24:11
to keep front of mind

00:03:24:11 - 00:03:25:17
when embarking

00:03:25:17 - 00:03:27:16
on a remediation project.

00:03:27:17 - 00:03:30:00
Yes, the science is definitely there

00:03:30:00 - 00:03:31:02
to back up the work

00:03:31:02 - 00:03:32:05
that needs to happen,

00:03:32:06 - 00:03:35:05
but the how and what is communicated to

00:03:35:07 - 00:03:37:15
community also needs to resonate

00:03:37:15 - 00:03:38:18
with them

00:03:38:20 - 00:03:40:04
in a meaningful way

00:03:40:04 - 00:03:41:15
where they've got time

00:03:41:15 - 00:03:45:15
to review, digest and come back with

00:03:45:17 - 00:03:46:22
because they're going to have questions

00:03:46:22 - 00:03:48:07
so they can come back and ask you

00:03:48:07 - 00:03:49:09
the questions that they have,

00:03:49:10 - 00:03:50:07
because you're not going to be

00:03:50:08 - 00:03:51:17
able to solve it all

00:03:51:17 - 00:03:53:00
in just one factsheet.

00:03:53:01 - 00:03:54:11
There's going to be ongoing

00:03:54:12 - 00:03:55:17
conversations that you

00:03:55:18 - 00:03:58:02
you would expect to occur.

00:03:58:04 - 00:03:59:19
So obviously in these PFAS

00:03:59:19 - 00:04:00:15
affected communities,

00:04:00:15 - 00:04:02:07
trust is already fragile

00:04:02:07 - 00:04:04:03
and maybe even even worse than that

00:04:04:03 - 00:04:05:02
in some occasions.

00:04:05:02 - 00:04:06:18
So what are organizations

00:04:06:18 - 00:04:07:08
most likely

00:04:07:08 - 00:04:09:06
to get wrong in those early,

00:04:09:06 - 00:04:11:05
early stages of engagement?

00:04:11:07 - 00:04:12:23
it might not be all organizations.

00:04:12:23 - 00:04:14:07
We're definitely getting better.

00:04:14:07 - 00:04:16:14
I would say just across the board.

00:04:16:14 - 00:04:19:14
When it comes to PFAS engagement,

00:04:19:20 - 00:04:21:20
it is different in a sense

00:04:21:20 - 00:04:22:19
where you're not dealing

00:04:22:19 - 00:04:25:09
with infrastructure, where you know

00:04:25:11 - 00:04:26:19
where something's going to be built,

00:04:26:19 - 00:04:29:13
you know what your timelines are.

00:04:29:15 - 00:04:30:15
there is something,

00:04:30:15 - 00:04:31:23
as I said, tangible.

00:04:32:00 - 00:04:33:04
You're building something.

00:04:33:04 - 00:04:36:05
It's quite easy for a community member

00:04:36:07 - 00:04:37:14
to get their head around

00:04:37:14 - 00:04:38:17
what to expect.

00:04:38:17 - 00:04:40:07
Whereas when you're dealing

00:04:40:07 - 00:04:41:13
with the intangible

00:04:41:13 - 00:04:43:12
and data and science

00:04:43:12 - 00:04:45:21
and they can't see it going in

00:04:45:21 - 00:04:47:18
with quite a lot of information

00:04:47:19 - 00:04:48:19
up front,

00:04:48:20 - 00:04:50:05
especially to a community

00:04:50:05 - 00:04:51:00
where you're looking to

00:04:51:01 - 00:04:51:19
actually build

00:04:51:19 - 00:04:52:22
an understanding,

00:04:52:22 - 00:04:54:21
rapport and relationship

00:04:54:21 - 00:04:56:10
with them in the long term

00:04:56:10 - 00:04:57:14
because you're not going to

00:04:57:15 - 00:04:59:01
clean this stuff up

00:04:59:03 - 00:04:59:15
a week,

00:04:59:15 - 00:05:01:14
you're really going to need

00:05:01:14 - 00:05:03:08
to take a couple of steps

00:05:03:08 - 00:05:04:23
back, assess

00:05:04:23 - 00:05:06:08
who you're actually speaking

00:05:06:09 - 00:05:09:09
to the very early stages, know

00:05:09:11 - 00:05:10:14
what their key drivers

00:05:10:14 - 00:05:12:12
influence interests are.

00:05:12:14 - 00:05:13:06
You know,

00:05:13:08 - 00:05:14:05
for example,

00:05:14:05 - 00:05:17:04
is it near agricultural property

00:05:17:06 - 00:05:20:16
IU in a heavily populated

00:05:20:18 - 00:05:21:21
suburban area?

00:05:21:23 - 00:05:24:15
those things need to be looked at prior

00:05:24:15 - 00:05:25:16
to actually coming up

00:05:25:16 - 00:05:26:18
with what

00:05:26:18 - 00:05:28:10
you're going to engage with them

00:05:28:10 - 00:05:30:19
and how you're going to engage them

00:05:30:21 - 00:05:34:00
as well, as opposed to here's

00:05:34:02 - 00:05:35:13
a piece of communication

00:05:35:13 - 00:05:38:01
with all of the technical information

00:05:38:03 - 00:05:39:10
to share directly

00:05:39:10 - 00:05:41:12
with that particular community member,

00:05:41:12 - 00:05:42:21
and they're

00:05:42:21 - 00:05:44:08
then expected to take that away,

00:05:44:09 - 00:05:45:08
decipher it,

00:05:45:08 - 00:05:46:19
and it can be quite

00:05:46:19 - 00:05:47:19
overwhelming as well

00:05:47:19 - 00:05:48:15
when you provide

00:05:48:15 - 00:05:49:23
that type of information.

00:05:49:23 - 00:05:51:00
And all of a sudden

00:05:51:01 - 00:05:52:18
the technical team stays,

00:05:52:18 - 00:05:54:14
but the people side

00:05:54:16 - 00:05:55:14
takes a step back

00:05:55:14 - 00:05:58:01
or at times, in some cases

00:05:58:02 - 00:05:59:21
not disappears.

00:05:59:23 - 00:06:01:10
So where does that community member

00:06:01:11 - 00:06:02:22
then go to ask questions?

00:06:02:22 - 00:06:04:15
Because the scientist is brilliant.

00:06:04:16 - 00:06:07:02
However, there needs to be that

00:06:07:02 - 00:06:09:01
in between in empathizing

00:06:09:01 - 00:06:09:21
and understanding

00:06:09:21 - 00:06:11:01
what that community member

00:06:11:01 - 00:06:12:21
has to say as well.

00:06:12:23 - 00:06:13:14
is facts

00:06:13:14 - 00:06:14:08
alone are not enough

00:06:14:08 - 00:06:16:09
when it comes to PFAS is it really is.

00:06:16:10 - 00:06:16:23
And also,

00:06:17:00 - 00:06:18:09
with science still evolving,

00:06:18:09 - 00:06:19:13
it must be difficult

00:06:19:15 - 00:06:20:10
being in a situation

00:06:20:10 - 00:06:21:08
to be able to communicate

00:06:21:08 - 00:06:22:09
that risk effectively.

00:06:22:10 - 00:06:23:10
Is that correct?

00:06:23:11 - 00:06:26:02
I would say, in short, yes, definitely.

00:06:26:04 - 00:06:27:11
technology and it's

00:06:27:13 - 00:06:29:04
the science has gotten so much better.

00:06:29:04 - 00:06:30:21
And if I look back to

00:06:30:21 - 00:06:32:15
when this first became

00:06:32:17 - 00:06:34:23
a prevalent issue, a known issue,

00:06:34:23 - 00:06:36:19
and it would be going back

00:06:36:19 - 00:06:40:12
ten, 12 years where we first started

00:06:40:14 - 00:06:42:19
embarking on this journey,

00:06:42:21 - 00:06:43:19
and in some cases,

00:06:43:19 - 00:06:46:02
maybe a little bit longer than that.

00:06:46:04 - 00:06:47:00
The technology's

00:06:47:00 - 00:06:48:14
moved so far ahead,

00:06:48:15 - 00:06:50:09
and being able

00:06:50:09 - 00:06:52:06
to communicate that in a simple way

00:06:52:06 - 00:06:53:19
to community, to reassure

00:06:53:19 - 00:06:56:07
them is also important.

00:06:56:07 - 00:06:58:05
And at we forget that.

00:06:58:05 - 00:07:01:00
So some remediation projects could take

00:07:01:01 - 00:07:02:01
say between

00:07:02:03 - 00:07:03:12
the time frames are dependent.

00:07:03:13 - 00:07:06:14
I'm not a environmental engineer,

00:07:06:16 - 00:07:07:16
so I won't try

00:07:07:17 - 00:07:09:07
to speak to the science to that.

00:07:09:07 - 00:07:11:02
But depending on those timeframes,

00:07:11:02 - 00:07:12:02
as the technology

00:07:12:02 - 00:07:13:20
changes, your messaging

00:07:13:20 - 00:07:15:20
and the information that you share

00:07:15:20 - 00:07:17:03
with the community

00:07:17:04 - 00:07:19:16
or stakeholders should also evolve.

00:07:19:16 - 00:07:20:19
So it can't be a set

00:07:20:19 - 00:07:22:12
and leave approach.

00:07:22:14 - 00:07:24:09
And you've coauthored a two part

00:07:24:09 - 00:07:26:08
weekly column on this very topic,

00:07:26:08 - 00:07:26:23
and in that

00:07:27:00 - 00:07:27:22
you talk about moving

00:07:27:22 - 00:07:29:15
beyond one way communication

00:07:29:15 - 00:07:30:21
to genuine involvement.

00:07:30:21 - 00:07:31:23
So what does sort of

00:07:32:00 - 00:07:33:00
meaningful engagement

00:07:33:00 - 00:07:34:16
actually look like in practice

00:07:34:17 - 00:07:37:02
on a PFAS project?

00:07:37:04 - 00:07:37:11
I guess,

00:07:37:12 - 00:07:39:10
moving beyond that communication

00:07:39:10 - 00:07:41:06
piece, and that's

00:07:42:10 - 00:07:45:08
when going out to community.

00:07:45:09 - 00:07:48:08
It's not about telling them

00:07:48:10 - 00:07:49:05
in more ways

00:07:49:05 - 00:07:50:18
that one way communication

00:07:50:18 - 00:07:52:16
where you have all your facts,

00:07:52:16 - 00:07:53:08
your figures,

00:07:53:10 - 00:07:54:21
your key information

00:07:54:21 - 00:07:56:22
and your communication

00:07:56:22 - 00:07:59:12
material ready to go yet

00:07:59:12 - 00:08:00:18
that's one part of it,

00:08:00:18 - 00:08:02:23
but it's also having a deep

00:08:03:00 - 00:08:04:00
understanding as to who

00:08:04:01 - 00:08:05:08
you're actually dealing with out

00:08:05:09 - 00:08:06:05
in that community.

00:08:06:07 - 00:08:07:12
in sparsely

00:08:07:14 - 00:08:08:16
populated areas,

00:08:08:17 - 00:08:10:02
agricultural areas,

00:08:10:02 - 00:08:13:01
to suburban and city centers.

00:08:13:03 - 00:08:15:05
Where there is PFAS prevalent,

00:08:15:05 - 00:08:17:14
there are going to be different drivers

00:08:17:14 - 00:08:19:03
that influence.

00:08:19:03 - 00:08:19:15
There are going

00:08:19:15 - 00:08:21:03
to be different interests

00:08:21:03 - 00:08:22:14
for those individuals.

00:08:22:16 - 00:08:25:12
If I use an example of, say,

00:08:25:14 - 00:08:28:11
if you're in a sparsely populated area,

00:08:28:12 - 00:08:30:05
there happens to PFAS

00:08:30:06 - 00:08:31:19
that needs to be remediated

00:08:31:19 - 00:08:33:02
as just a scenario

00:08:33:02 - 00:08:35:06
that particular community member

00:08:35:06 - 00:08:36:08
and or stakeholder

00:08:36:09 - 00:08:39:02
may have livestock on their property.

00:08:39:04 - 00:08:40:18
So going in there

00:08:40:18 - 00:08:42:11
with all of the science

00:08:42:11 - 00:08:46:09
but not having information, say around

00:08:46:14 - 00:08:49:08
how could this affect properties

00:08:49:08 - 00:08:51:13
within that agricultural space

00:08:51:14 - 00:08:53:09
would be a little bit of a mess.

00:08:53:09 - 00:08:55:23
So getting a clear understanding

00:08:55:23 - 00:08:57:14
as to who the stakeholders are

00:08:57:15 - 00:08:58:11
that we need

00:08:58:13 - 00:08:59:00
speak to,

00:08:59:01 - 00:08:59:22
and that's pretty,

00:08:59:23 - 00:09:00:20
I guess that's an approach

00:09:00:20 - 00:09:02:22
that we take across a lot of projects.

00:09:02:22 - 00:09:04:04
But the nuance for

00:09:04:04 - 00:09:05:00
this is knowing

00:09:05:00 - 00:09:05:14
what's in it

00:09:05:14 - 00:09:07:07
for that particular stakeholder

00:09:07:07 - 00:09:08:23
in wanting to understand more.

00:09:09:00 - 00:09:10:10
That might be nuance

00:09:10:10 - 00:09:12:02
to their particular property,

00:09:12:03 - 00:09:13:18
say, for example, as well.

00:09:13:18 - 00:09:14:22
So it's very difficult

00:09:14:22 - 00:09:16:05
to develop a one size fits

00:09:16:06 - 00:09:18:01
all engagement program.

00:09:18:01 - 00:09:19:06
I'm guessing based on that,

00:09:19:07 - 00:09:20:10
it's more about assessing

00:09:20:10 - 00:09:21:11
who you're dealing with,

00:09:21:11 - 00:09:22:10
what their issues are

00:09:22:10 - 00:09:23:15
and what their concerns are,

00:09:23:16 - 00:09:24:22
and then trying to work

00:09:24:22 - 00:09:25:23
something around that.

00:09:26:00 - 00:09:29:00
Would that be It would be one example

00:09:29:06 - 00:09:31:21
it was a PFAS project for a client,

00:09:31:21 - 00:09:33:04
and a component of

00:09:33:05 - 00:09:34:22
that was getting access to ensure

00:09:34:22 - 00:09:36:09
that we could do the monitoring

00:09:36:09 - 00:09:37:07
that was required.

00:09:37:07 - 00:09:38:18
So the technical teams

00:09:38:18 - 00:09:40:18
were able to go out and undertake

00:09:40:18 - 00:09:41:09
that work.

00:09:41:10 - 00:09:43:21
This particular location,

00:09:43:23 - 00:09:45:09
we had a couple of sites.

00:09:45:09 - 00:09:48:08
One of the sites was a high rise

00:09:48:10 - 00:09:51:10
apartment building and it also

00:09:51:10 - 00:09:52:11
it was quite close

00:09:52:11 - 00:09:54:22
to a main waterway as well

00:09:54:23 - 00:09:57:10
where there was fishing, boating,

00:09:57:12 - 00:09:59:05
people swimming in the water.

00:09:59:05 - 00:10:01:10
So for this particular project,

00:10:01:10 - 00:10:03:02
this particular case, that ongoing

00:10:03:03 - 00:10:04:12
monitoring, determined

00:10:04:12 - 00:10:07:14
that there wasn't an issue

00:10:07:16 - 00:10:09:17
that needed to be resolved.

00:10:09:17 - 00:10:10:15
As such.

00:10:10:16 - 00:10:12:11
However, we needed to undertake

00:10:12:12 - 00:10:14:14
that ongoing monitoring.

00:10:14:15 - 00:10:16:10
And as part of that,

00:10:16:12 - 00:10:18:03
knowing how to engage

00:10:18:03 - 00:10:18:16
with that

00:10:18:16 - 00:10:21:01
particular stakeholder community

00:10:21:02 - 00:10:23:03
group was very important,

00:10:23:03 - 00:10:25:21
because we're not going to them

00:10:25:21 - 00:10:28:08
in presenting a potential

00:10:28:09 - 00:10:29:19
what if you have

00:10:29:19 - 00:10:31:21
contamination on your property,

00:10:31:21 - 00:10:33:16
but we're also asking them

00:10:33:16 - 00:10:34:20
for access

00:10:34:20 - 00:10:35:07
on an

00:10:35:08 - 00:10:36:17
ongoing basis

00:10:36:17 - 00:10:39:09
and to accommodate us to do our work

00:10:39:09 - 00:10:42:19
at the site quite common as well.

00:10:43:15 - 00:10:45:04
that relationship and trust

00:10:45:05 - 00:10:46:21
is really important

00:10:46:21 - 00:10:49:18
because if you don't have that,

00:10:49:19 - 00:10:50:11
you always come

00:10:50:11 - 00:10:51:16
to a bit of a standstill.

00:10:51:16 - 00:10:52:15
In some cases

00:10:52:15 - 00:10:55:18
where you don't get access to undertake

00:10:56:05 - 00:10:57:06
the assessments

00:10:57:06 - 00:10:58:01
and the studies

00:10:58:01 - 00:11:00:02
that are needed, or the monitoring

00:11:00:02 - 00:11:01:16
and the stakeholder or community

00:11:01:16 - 00:11:02:12
member

00:11:02:14 - 00:11:04:04
doesn't get the information

00:11:04:04 - 00:11:05:15
that they need either.

00:11:05:17 - 00:11:07:06
it's all over in multi-layered,

00:11:07:07 - 00:11:07:17
of course.

00:11:07:17 - 00:11:08:16
And then let's add

00:11:08:16 - 00:11:09:12
another layer to that.

00:11:09:12 - 00:11:11:16
And that's PFAS regulation

00:11:11:16 - 00:11:13:00
through various government levels.

00:11:13:00 - 00:11:14:16
And that must also add

00:11:14:16 - 00:11:15:13
to the complexity

00:11:15:13 - 00:11:16:06
and the difficulty

00:11:16:06 - 00:11:17:20
of handling these situations.

00:11:17:20 - 00:11:18:18
Is that right?

00:11:18:20 - 00:11:19:11
It does.

00:11:19:11 - 00:11:21:07
From a technical perspective,

00:11:21:09 - 00:11:22:14
the variations do

00:11:22:15 - 00:11:26:02
make sense from a community perspective

00:11:26:13 - 00:11:27:19
as far as they're concerned.

00:11:27:19 - 00:11:29:10
If I was a community member,

00:11:29:11 - 00:11:31:06
it's a broad brush.

00:11:31:08 - 00:11:32:20
It's all the same to them.

00:11:32:20 - 00:11:36:22
So being sensitive and listening

00:11:37:00 - 00:11:38:10
and being able to explain

00:11:38:10 - 00:11:39:20
that to is important.

00:11:39:20 - 00:11:42:03
And being patient around

00:11:42:03 - 00:11:44:08
they may not be ready to listen to you

00:11:44:08 - 00:11:45:05
just as yet

00:11:45:06 - 00:11:46:15
at times as well,

00:11:46:17 - 00:11:47:19
because it can be

00:11:47:19 - 00:11:49:16
quite an emotional topic

00:11:49:16 - 00:11:51:04
for some community members,

00:11:51:04 - 00:11:52:16
depending on how they're affected

00:11:52:16 - 00:11:56:01
by the issue or the challenge to

00:11:56:21 - 00:11:57:19
to understand

00:11:57:19 - 00:12:00:13
and be ready to actually speak to you

00:12:00:15 - 00:12:01:23
in a meaningful way.

00:12:01:23 - 00:12:02:17
So it's just having

00:12:02:17 - 00:12:04:05
that respectful approach

00:12:04:05 - 00:12:05:20
to how you engage

00:12:05:21 - 00:12:08:03
in terms of communicating that.

00:12:08:03 - 00:12:10:07
Because if the organization

00:12:10:07 - 00:12:11:22
doesn't explain the why

00:12:11:23 - 00:12:13:17
behind, say, a particular

00:12:13:17 - 00:12:15:09
regulatory change

00:12:15:11 - 00:12:17:07
and you keep pushing ahead

00:12:17:07 - 00:12:20:09
with the program, but internal team

00:12:20:23 - 00:12:22:15
or organization side, you're like,

00:12:22:15 - 00:12:23:13
we're all across it,

00:12:23:14 - 00:12:24:18
we know what we're doing.

00:12:24:18 - 00:12:26:18
But that message isn't communicated.

00:12:26:19 - 00:12:28:19
It may be perceived,

00:12:28:19 - 00:12:31:13
and in most cases it's not true.

00:12:31:13 - 00:12:33:05
But the community member may feel

00:12:33:05 - 00:12:33:17
as if you're

00:12:33:17 - 00:12:35:14
with held information from them.

00:12:35:14 - 00:12:37:17
So having that transparency,

00:12:37:17 - 00:12:39:06
and that's where I guess,

00:12:39:06 - 00:12:40:23
that proactive communication

00:12:40:23 - 00:12:42:04
and having an understanding

00:12:42:04 - 00:12:43:01
as to

00:12:43:03 - 00:12:44:11
what does the remediation

00:12:44:11 - 00:12:46:11
or the cleanup program look like,

00:12:46:11 - 00:12:47:10
what are the steps

00:12:47:10 - 00:12:49:02
from a technical perspective,

00:12:49:02 - 00:12:51:13
and where can we proactively pick

00:12:51:15 - 00:12:52:19
key activities

00:12:52:19 - 00:12:54:11
to communicate to community,

00:12:54:11 - 00:12:55:00
to start

00:12:55:00 - 00:12:57:01
building that trust and rapport

00:12:57:01 - 00:12:59:18
so that they know what you're doing?

00:12:59:19 - 00:13:01:10
You're not just surprising them,

00:13:01:11 - 00:13:02:10
say a couple of weeks.

00:13:02:10 - 00:13:03:19
There are a couple of days before

00:13:03:19 - 00:13:05:21
with needing to do something,

00:13:05:21 - 00:13:08:04
and it's almost building that

00:13:08:06 - 00:13:10:17
education playbook as to

00:13:11:16 - 00:13:12:19
how to help the community

00:13:12:19 - 00:13:14:05
better understand

00:13:14:07 - 00:13:15:15
how we're cleaning up

00:13:15:15 - 00:13:17:22
this emerging contaminant.

00:13:18:00 - 00:13:20:04
how important is cultural awareness,

00:13:20:06 - 00:13:21:00
especially

00:13:21:00 - 00:13:21:22
when you're dealing with, say,

00:13:21:23 - 00:13:22:21
First Nation communities?

00:13:22:21 - 00:13:23:22
So not just Australia.

00:13:23:23 - 00:13:24:14
Could be Canada

00:13:24:15 - 00:13:25:13
could be the US

00:13:25:14 - 00:13:27:03
anywhere else in the world.

00:13:27:05 - 00:13:28:11
First Nations engagement

00:13:28:11 - 00:13:30:07
I know speaking for PhD,

00:13:30:08 - 00:13:33:10
we we pride ourselves in First

00:13:33:12 - 00:13:34:12
Nations leading

00:13:34:13 - 00:13:36:12
First Nations conversations.

00:13:36:12 - 00:13:38:21
I know the teams that I've worked in,

00:13:38:22 - 00:13:41:06
we've always taken that approach

00:13:41:06 - 00:13:43:04
where we engaged.

00:13:43:04 - 00:13:45:14
We've got a First Nations member who

00:13:45:16 - 00:13:46:14
where we can,

00:13:46:15 - 00:13:47:10
is local

00:13:47:11 - 00:13:50:18
to that particular region, understands

00:13:50:21 - 00:13:51:19
the community

00:13:51:19 - 00:13:54:06
and is able engage with them,

00:13:54:06 - 00:13:56:04
and it is separate to the wider

00:13:56:04 - 00:14:00:01
community as well to respect

00:14:00:03 - 00:14:00:22
that particular

00:14:00:23 - 00:14:02:03
First Nations

00:14:02:03 - 00:14:04:01
or traditional owner group,

00:14:04:01 - 00:14:05:19
where we've had the one

00:14:05:20 - 00:14:07:06
on one discussions

00:14:07:08 - 00:14:10:05
with that, I will say it takes time

00:14:10:05 - 00:14:11:09
and we have to

00:14:11:10 - 00:14:15:09
respect those times as well because it

00:14:15:11 - 00:14:16:15
it is a complex issue

00:14:16:15 - 00:14:17:15
that we're dealing with.

00:14:17:15 - 00:14:19:20
And you can't rush building

00:14:19:20 - 00:14:21:08
that understanding.

00:14:21:10 - 00:14:23:05
Let's take a look ahead for, say,

00:14:23:06 - 00:14:24:13
5 to 10 years.

00:14:24:15 - 00:14:26:01
As PFAS regulation

00:14:26:01 - 00:14:27:10
matures and community

00:14:27:12 - 00:14:28:22
expectations rise,

00:14:28:23 - 00:14:31:04
what will differentiate organizations

00:14:31:04 - 00:14:32:02
that lead on

00:14:32:04 - 00:14:34:06
PFAS engagement from those that

00:14:34:06 - 00:14:35:19
that fall behind?

00:14:35:21 - 00:14:38:21
That's a really big question, Ben, and

00:14:39:06 - 00:14:40:12
a good one too.

00:14:40:14 - 00:14:42:07
And I would say over the next

00:14:42:07 - 00:14:45:09
5 to 10 years, organizations

00:14:45:11 - 00:14:47:03
that lead will be

00:14:47:03 - 00:14:48:16
the ones that treat engagement

00:14:48:16 - 00:14:50:04
as a core capability.

00:14:50:04 - 00:14:51:22
And when I say engagement,

00:14:51:23 - 00:14:54:13
it is that upfront early engagement,

00:14:54:13 - 00:14:56:07
yes, it applies to all projects,

00:14:56:07 - 00:14:58:03
but in particular for PFAS,

00:14:58:04 - 00:14:59:13
because you want to build

00:14:59:13 - 00:15:01:09
that trust and rapport early

00:15:01:11 - 00:15:02:13
trust in particular.

00:15:02:14 - 00:15:03:09
That is what

00:15:03:10 - 00:15:05:17
equates to a social license.

00:15:05:17 - 00:15:08:17
And a social license isn't earned.

00:15:08:19 - 00:15:11:06
it's not a ticket that you get

00:15:11:08 - 00:15:13:00
I guess at the start

00:15:13:00 - 00:15:14:13
or midway through your project

00:15:14:13 - 00:15:16:12
or after your first info session

00:15:16:12 - 00:15:17:08
with community,

00:15:17:08 - 00:15:20:06
and you keep at the back pocket and

00:15:20:08 - 00:15:21:03
that's it.

00:15:21:05 - 00:15:22:22
It's something that you've got to

00:15:22:23 - 00:15:25:10
work on to maintain over time.

00:15:25:10 - 00:15:26:14
And that may be

00:15:26:16 - 00:15:28:07
not just for the life of the project.

00:15:28:07 - 00:15:31:05
It could also be a little bit after

00:15:31:07 - 00:15:33:13
and that to me,

00:15:33:13 - 00:15:35:11
I would say over the next

00:15:35:11 - 00:15:36:13
5 to 10 years,

00:15:36:13 - 00:15:37:21
those organizations

00:15:37:21 - 00:15:39:10
who really take

00:15:39:10 - 00:15:41:09
that proactive approach

00:15:41:11 - 00:15:42:13
in investing

00:15:42:13 - 00:15:44:10
in those early relationships

00:15:44:11 - 00:15:46:20
will be the ones that really,

00:15:46:22 - 00:15:47:09
I guess,

00:15:47:09 - 00:15:48:20
start to build that guess,

00:15:48:20 - 00:15:50:08
meaningful social license

00:15:50:08 - 00:15:51:09
with community,

00:15:51:09 - 00:15:53:07
but also those

00:15:53:07 - 00:15:55:02
that stay visible,

00:15:55:02 - 00:15:56:13
accountable and are present.

00:15:56:13 - 00:15:59:17
And that's a tough one, because usually

00:15:59:19 - 00:16:00:17
with PFAS you're

00:16:00:17 - 00:16:01:23
dealing with

00:16:02:01 - 00:16:04:02
highly emotive stakeholders

00:16:04:02 - 00:16:05:13
and community members,

00:16:05:13 - 00:16:08:14
and sometimes it just takes time

00:16:08:16 - 00:16:09:12
to take the heat

00:16:09:12 - 00:16:10:16
out of the conversation

00:16:10:16 - 00:16:13:05
before someone is ready to engage you

00:16:13:05 - 00:16:14:17
in a meaningful way.

00:16:14:19 - 00:16:15:22
If that's the case,

00:16:15:22 - 00:16:17:08
that's what needs to happen.

00:16:17:08 - 00:16:19:13
And those early

00:16:19:13 - 00:16:20:22
meaningful relationships

00:16:20:22 - 00:16:24:02
will really help in that space.

00:16:24:08 - 00:16:26:12
Ultimately, leadership on PFAS

00:16:26:13 - 00:16:29:12
won't be judged, in my view.

00:16:29:14 - 00:16:31:03
On the solution,

00:16:31:04 - 00:16:33:03
the scientist is a lot better.

00:16:33:05 - 00:16:34:16
We've got the solutions.

00:16:34:16 - 00:16:36:07
It's the experience

00:16:36:07 - 00:16:38:00
that that individual or community

00:16:38:00 - 00:16:39:13
member has throughout

00:16:39:15 - 00:16:41:03
their immediate process.

00:16:41:03 - 00:16:43:15
If you can build that trust, rapport

00:16:43:15 - 00:16:44:14
and you know what,

00:16:44:15 - 00:16:46:06
they may be really upset

00:16:46:07 - 00:16:47:20
at the whole situation

00:16:47:20 - 00:16:49:22
and the remediation.

00:16:49:23 - 00:16:52:16
However, if you give them a fair

00:16:52:16 - 00:16:54:00
and just process

00:16:54:00 - 00:16:55:13
and you're transparent

00:16:55:13 - 00:16:56:20
in how you're going to

00:16:56:21 - 00:16:58:02
undertake the work,

00:16:58:03 - 00:16:59:11
they'll be happy with that.

00:16:59:11 - 00:17:00:17
Or I won't say happy,

00:17:00:17 - 00:17:02:01
they'll be content with that,

00:17:02:01 - 00:17:04:06
and they'll still be unhappy

00:17:04:07 - 00:17:06:10
that it needs to be remediated,

00:17:06:12 - 00:17:08:23
but they'll appreciate the outcome

00:17:08:23 - 00:17:10:13
that you're trying to achieve.

00:17:10:15 - 00:17:11:14
then that's a great way to finish.

00:17:11:14 - 00:17:12:15
Sharon, thanks for your time

00:17:12:17 - 00:17:13:13
and your insights.

00:17:13:13 - 00:17:14:05
Appreciate

00:17:14:07 - 00:17:16:07
Thank you for having me, Ben.

00:17:16:09 - 00:17:16:14
Well,

00:17:16:14 - 00:17:18:04
if there's one takeaway from today's,

00:17:18:04 - 00:17:19:09
this PFAS

00:17:19:11 - 00:17:21:11
isn't just a contamination challenge.

00:17:21:11 - 00:17:22:20
It's a trust challenge.

00:17:22:20 - 00:17:24:00
And the organizations

00:17:24:00 - 00:17:25:06
that recognize engagement

00:17:25:06 - 00:17:26:19
as a core capability,

00:17:26:20 - 00:17:28:05
not just a communications

00:17:28:05 - 00:17:29:05
task, will be

00:17:29:05 - 00:17:31:10
the ones that navigate it successfully.

Why this conversation matters

“Ultimately, leadership on PFAS won't be judged on the solution. It will be judged on the experience that community members have throughout the remediation process.” – Sharon Sebastian

Most organisations approach PFAS as a technical challenge. Investigate the contamination. Assess the risks. Develop a remediation strategy.

But for communities living with PFAS, the challenge is often much more personal. It is uncertainty, anxiety and a lack of clear answers about what contamination means for their health, environment and future.

In this episode, Sharon Sebastian joins Ben Hall, Global Thought Leadership Manager at GHD, to explore why PFAS engagement is no longer just about communication. It is about trust, transparency and building the social licence needed to support long-term remediation programs in increasingly complex community environments.

Key takeaways

  • PFAS engagement is fundamentally different because communities are often dealing with uncertainty, anxiety and evolving science
  • Facts and technical data alone are rarely enough to build trust or community confidence
  • Successful PFAS programs prioritise early engagement, transparency and ongoing dialogue
  • Cultural awareness and tailored engagement approaches are essential, particularly when working with First Nations and diverse communities
  • Organisations that treat engagement as a core capability will be better positioned to build trust and maintain social licence over the long term
