I guess the challenge here, and this something I frequently hear from small communities, is that the government changes requirements, but often that change doesn't come with any corresponding funding so that these municipalities can address the new requirements. This is right across the board, whether it's municipally owned airports or fire departments or drinking water and waste-water infrastructure.
The challenge is that some small communities don't actually have water treatment plants because they have clean water that comes right out of the ground and they're able to meet the other health guidelines without too much of a problem. Now you change the manganese guidelines, and all of a sudden they have a challenge on their hands that potentially requires them to build a water treatment plant that cost tens of millions of dollars. These are communities where their entire tax roll is just a few million dollars per year.
The larger question for the federal government is this: How can you expect communities to meet these guidelines, given their limited financial tools and given the fact that the implications for their budgets are totally unrealistic?
