Distance from old outhouses?

I'm trying to figure out where to get a well drilled at my new property in northern Maine. There are a couple old outhouses that haven't been used in many years (I think). I know people say it should be 100 feet away but wanted to get opinions. Having a hard time figuring out where to get the well drilled for it to make sense and be close to the cabins and off a driveway for the drillers but not be too close to the outhouses..

How deep are wells in that area, typically?

I put mine in at 150 ft min.  I did not want to take a risk with an expensive well.

I assume a person can put a well anywhere they want but ...

Isn't well placement based on hydrogeology?

Something to do with soil types, where the water table is, the direction of water flow, etc?

Seems to me a good driller would know the best place to try to hit water.  Am I wrong?

My experience is in Maine they ask you where you want it assuming that you probably want it as close to your abode as possible (which I would like - not sure if im going to use a hand pump or plumbing but both the closer the better). There just happens to be two outhouses close to two cabins that are fairly close to each other. So I'm wondering what people's experiences and thoughts are about outhouses and wells.

They are about 160 feet deep at a minimum.
