The ONLY river I know worse than that is THE OHIO.
It gets over 30 chemical plants spills running into it from Pittsburgh are thru West Virginia and down into Ohio.
Ya could grow a third eyeball or a second head drinking water from the faucets in Cincinnati..
In my county we have artesian springs from some underground rivers flowing thru the state.. We also tap into those rivers underground for some really pure water. Ohio is full of Limestone underground.
Ya has to filter the minerals but at least in my county its pretty decent..
