Do not know if any can answer this one however, the well pump in a cubby hole in the foundation has a ground another wire ran to the pump, but i noticed it is not connected ...

Well you only want to be grounded at earth at one point so thats why the well is disconnected.

old style solid grounding rods need to be at least 8 foot in the ground or in a trench 8 foot long by 3 foot deep assuming
if your ground rod is not at least 8 foot down then its doing very little good
alternatively you may ground the house to the well assuming the well is deep enough having multipl grounds is not a issue unless a short or back-feeding is a concern infact is a single 8 foot is not a option mutlipl 4 foots will do tho it is not ideal

The electrical service is to be connected thusly:

At the first point of disconnect, (the breaker panel, or an adequately sized disconnect switch as close as possible to the electric meter between the meter and the breaker panel) the grounded phase conductor (neutral) and the grounding electrode conductor (earth ground) are to be connected together. After the first point of disconnect, the neutral and earth ground are separate.

The earth ground conductor (sized based on the amperage of the service) is to be connected to a metal water line within five feet of where the metal water line enters the structure. If the structure is metal framed, the structure must be bonded to the earth grounding system.

Additionally, another earth ground conductor is to be connected to an electrode buried in the ground.
