Where I hunt and fish IRL, you can drink straight from the streams and small lakes safely.(except during spring melt) So we can't make pure water in salem, because we make it impure by existing.
Already been said, but this is total BS. If you're really as outdoors-y as you say, you should know that drinking water straight from a lake/river isn't safe at all. Water quality took a dip when it was utilized by early settlers, but the "untainted waters" of the world were/are equally filthy before. Even nowadays, if you head out into completely unpopulated areas, you're advised to boil your water before you use it, because natural river water is full of horrible horrible parasites and such.
100% natural river water = 100% natural animal toilet water. Ever seen underwater footage of hippos? They don't give a crap about crapping in the water they're in. It's pretty much the same with all animals.
Maybe you could argue that water was purer before the existence of life, but I still wouldn't believe you, because minerals can still be dissolved in water. The only way to get "100% pure water" is to distill it, which I don't believe happens naturally anywhere. Granted, 100% pure water isn't actually good for growing things, since they need minerals and such to thrive.

The devs could go the route of having lakes/rivers all be 1.0, and then have people use dowsing to find springs to get higher purity. (although I'd also like a time consuming way to improve water quality by the bucket, too)
