In the US it is suggested to test well water (with no previous problems) once a year.
We treat our home's well water with an inline UV purification system. We have a Hallett. We recently got it tested by an independent lab and there's no bacteria. We also have a sediment filter. We wrote off the equipment as a medical deduction on our taxes.
