On the other hand, on the west coast the likely cause of water contamination issues is a major earthquake. In which case gas would most likely be out longer than power. The only reliable solution is to have a backup that’s not reliant on infrastructure. I.e everyone should have a camp stove and a couple of bottles of propane for it or an alternative self reliant solution that’s good for 3 or so days.
