When a well is no longer needed, California law requires proper destruction—not just covering it up. Improperly abandoned wells become contamination pathways that can affect entire aquifers.
When to Abandon a Well

- Well is dry or produces inadequate water
- Well is contaminated and treatment isn't practical
- Replacing with a new well
- Property development requires removal

The Destruction Process
