But an excavator wouldn't?
Ms. Taylor it is not as precise is what I’m saying. It’s not even that it would come up next to the sewer line but
that if you have a big open space right next to that, the potential for that to collapse, to break, is much greater
than if you have one small part that is being, one secant pile is being drilled.

What about on the bottom? What on the bottom is going to stop it?

Ms. Taylor That capped area would be basically open space for anybody that was living there if there was
such a development that could be walked on and used for open space. There wouldn't be any structures that
would be built on that.

Ms. Taylor | would say that is more likely if you remove it than if you built the secant wall.
Alderman Dowd
| don’t think some of the people here have heard your explanation of the approach that you are tending to use
and | think if you explain how you are going to contain that area and address the potential of not having leaks
and all of that and how it is built will probably answer a lot of questions that you might get.

it is a water supply for several communities that take their drinking water and their firefighting needs or
whatever from the Merrimack.
Can this be looked upon financially as a multi-state type of issue, because | imagine that there are toxins and it
gets into ... is this particular area prone to flooding within the 500,000 or biblical flood plain area? When you do
encapsulate it, can it potentially leak and can it be more of a problem downstream as well?

approached by a pollution removal expert from Canada who just read in the paper that there were
conversations taking place and | did refer him. So I’m not sure whether you were in contact with him or not but
he did forward a thumbnail sketch of an estimate as well.
Ms. Taylor_| am unaware of that.
Mr. Millan-Ramos | haven’t received any communication in that regards.
Alderman Lopez
Well he might be in the audience so I’m sure he could make public comment.

The other alternative and | don’t know if this one is possible is expand the size of the containment area so that
everything that is contained is below ground held in by the secant wall and not by the retaining wall above
ground.

lagoon, the other one is totally covered with sand and virtually solid in consistency, so much that you can walk
on top of it.
Ms. Taylor We have some pictures here too of the material and what it looks like, we can show them to you
now or we can show them to you afterwards.
President McCarthy
Whatever makes the most sense for your presentation.
