Linky no worky. I'm assuming this is about the Natives as usual. If so the two main problems are the same as they've always been. One, the Natives are living in a marshy area where the water is naturally dirty and unhealthy to ingest. And two, even when the government trains them to operate the water purifying system they don't bother to do so. Or whoever is train gets fired for ending up on the losing side of the reserve politics. Or, sadly, goes on a drunken tear and the equipment freezes up in winter and is basically destroyed. Take your pick. The government lives up to their part of the deal but for whatever reason the Natives drop the ball on their end.
Again, the correct solution is to put an end to the reserves and let the natives finally just move to a decent place to live.
