That's more honest, but quite the goalpost move.

The local population is probably allowed to complain that you built the reservoir with toxic waste, too, or that you filled the old well with construction debris.

It's not a goalpost move though, as there was never a guarantee to remain on well water.

But anyway I personally would find someone offering well water if I don't like the reservoir. And I've been using DuckDuckGo exclusively for search since they first appeared, so I've never had to deal with what Google's doing. I know the reservoir exists, but I've never drank from it.
