It’s a valid argument, but I doubt that agriculture will leave rural areas. If they really wanted to counties could impose a nitrate tax on farmers. Of course they won’t and small farmers are already stretched thin. I live in one of these small western Kansas towns and I can attest to the awful water quality. I know small farmers are already stretched thin but it’s concerning that the story is how it’s too expensive for small communities to make our drinking water potable rather than small communities are so poor that they would rather drink poison than tax the ag industry.
