Is your guess that shocking the well has as much effect on the water and the system after it leaves the well (i.e. filter, pump, pipes, tank) as it does on the water in the well?
Just curious as it seems at least around here every time there is a "boil water" order it is because some contamination has entered the system some place past the well field.
