The only way is if you have a bad cement job around your surface casing, which is the protective pipe cemented in to protect the ground water. It is a rarity.

And can be checked before proceeding with a bond log. If there's a problem, the cement job can be 'squeezed' (set packers above and below after perforating the casing in the problem interval and pump cement into the problem interval to seal any bad spots).

Most wells use intermediate casing inside the surface casing, also cemented into place which should seal the wellbore near the surface. It, too, can be checked and remediated, if necessary.
