There's some sort of authority that has jurisdiction in the Susquehanna River watershed in PA. There was an article in Lancaster Farming a couple of months ago that dealt with this. I think they were just looking at large users maybe over 10,000 gpd. The rational was that in times of drought, the large users would have to either curtail their usage, pay a fee on what they used or switch to an alternative source.
I think that was the source of the rumor. There was no mention of small household wells.
