A little off-topic, but a fearless prediction:
Before this administration is over, I expect the EPA to declare that WELL WATER also comes under its jurisdiction.
Rationale will be that since wells tap into "groundwater", drilling a well could impact the condition of underground aquifers, etc.
And with that, we will see requirements that before permission is granted to drill a new well, an EPA inspection or enviornmental impact report will be required -- and that numerous property owners building new homes will be denied such permits.
This is coming...
