I don't know when "we" (the taxpaying U.S. citizens) got the idea to fund anything to do with the "indigenous" peoples of this country. Granted, damage had been irreparably done to them for decades as we stripped them of their lands. But now, in the 21st century, these people can do basically anything they want with their land and their own welfare. Many have thrown up Casinos and other business's that make large amounts of revenue. All of it tax exempt. The real issue here are the tribal nation's themselves. One "nation" wants nothing to do with the other. Instead of pooling their economic resources, to help benefit all native Americans, they selfishly keep the resources within the "tribal nations." Some nations have benefitted while others remain destitute. Looking to the "white man's government" to settle their problems didn't work well for them in the past and it won't now. Simply put, if the water was screwed up by the White man's industrial or farming pollution, let them sue to recoup the funds necessary to clean it up. The government should have no part in anything to do with the matter.
