We have more than enough resources, but a lot of people don't want to pay taxes to clean it or restrain corporations from polluting our water supply inn the first place. I'm guessing that plenty of people in this woman's own town were cheering Trump's slashing of the EPA's budget and deregulating clean air and water. Just this week the administration announced plans to kill off or delay limits in the amount of PFAS in the drinking water. They argue it's too expensive to limit or filter the poison but then give no-bid contracts out to their unqualified friends for tens of millions of dollars and spend a trillion bombing other countries for no reason so it's pretty clear where the priorities are and it isn't with us.
You are mixing local and federal politics. This is a town issue and would likely have happened regardless of who occupied the Oval Office
