Planting White Pine next to a well??

[wannabeonetoo]

HERE IS A QUESTION FOR THE PLANTING PROS.
My wife has a garden plan drawn up by a landscape designer and they have 3 eastern white pines to be planted near our well (it's a dug well approx. 25ft. dp.).
The closest one is about 10'6'' from the centre of the well.  Is this too close to plant?  Are the roots invasive?

I know willows can be invasive, and I figure most other trees are also to a certain extent.

Roots generally grow as far as the branches on just about any tree except maybe a fig.

I guess what type of well it is matters too.

Fieldstone well about three feet across, spring well with cement sides like a cistern, pump well with 3" pipe?

Still, I would say that is far too close if the top of the well is above ground or open.

The tree will become a future problem for the well site as the tree enlarges over time. The closer it is to the well the sooner it will become a problem. If this is going to remain an active well for some time, a minimum distance of 25-30 feet might be better.
