:23:02
	were drawn into the city wells here
and Well H over there,
:23:07
	and then pumped
into east Woburn homes.
:23:10
	So I'll need to inspect
and map the debris,
:23:13
	drill some monitoring wells,
:23:16
	conduct seismic tests, and so on.
:23:19
	And you're talking about you
and a couple of assistants?
:23:23
	No. I mean a team of
geologists and engineers.
:23:26
	- A team?
- A big team.
:23:33
	It's actually quite exciting.
:23:35
	The nature of the contour
here means there's an effect -
:23:39
	named after me, actually...
:23:44
	In the shop, Mr Roberts,
you used solvents to clean brushes?
:23:50
	What would you've done with that
stuff back in the 1970s and '80s?
:23:55
	- Used solvent? Put it in drums.
- 35-gallon drums?
:24:00
	What would you do with full drums?
:24:03
	- Don't know.
- They just went?
:24:05
	- Never noticed.
- Did you dump them?
:24:08
	- No.
- Nothing like that?
:24:12
	- Never noticed anyone who did?
- No.
:24:15
	Just disappeared...
:24:18
	What were your duties
at Grace, Mr Shalline?
:24:21
	Discharge to the drains. Be sure
we weren't polluting the air.
:24:26
	Then you know that chemicals
were deposited behind the plant?
:24:32
	I don't know that.
:24:34
	Six barrels of toxic waste
:24:36
	were found there in a pit
and exhumed by city inspectors.
:24:40
	- You didn't know?
- Nope.
:24:42
	Back in 1965 did you
clean metal parts with solvent?
:24:47
	Yes.
:24:48
	- What kind?
- That I couldn't say.
:24:51
	Did you ever notice
the name trichlorethylene or TCE?
:24:56
	I don't know.
:24:57
	But you'd put it in barrels
when you were finished, right?
