Not being a smart aleck at all, but using stream water to cool industrial processes warms up the water. If the water is heated too much the amount of oxygen in the water is significantly reduced which can be harmful for some fish (like trout). As a trout fisherman I would be very angry if such a process hurt the trout population at my favorite fishing hole.The sCO2 can be heated in a variety of ways and cooled using stream water. It does not even need to be clean water.
Sadly there will always be some problem that someone (or some group) will have with just about any energy source.
