I will repeat a comment from below. There are over 150k water utilities alone in the US.
Passing the buck to the Federal Government is not understanding the problem.
There are 150 million taxpayers and the federal government regulates all of them. I don’t see why they can’t audit 0.1% of that. If there are 150,000 utilities then absent some regulation, some of them will fuck up. If we want fewer fuckups, you need regulation.
Usually these commenters are not from the US but get energized by US topics and misunderstand scale of things. E.g., they come from countries with a single nationalized entity for many things.
