Re: Shallow or deep well and how to test it.
1.5" diameter is unlikely to be a deep well. A deep well is usually drilled, and needs to be large enough to accommodate either a submersible pump or two pipes for a deep-well jet.
It seems strange that it's PVC. I've never heard of a well with PVC pipe, unless it turns to steel just below the surface. Most driven wells are a pipe that's been pounded into the ground. At the bottom of the pipe is a well point, which has a sharp iron point and a screen to allow water to flow into the pipe.
Probably the way to test it is to hook a pump to it and see how much water you get out. You might be able to rent a pump for this purpose.
