How clean does the water have to be for KNF brews? I know it has be unchlorinated but doesn’t need to be soft like for JWA. Would pond water work? River water? How murky grimey green can one go?

Water is important, just behind air and sunlight in terms of how much it matters. The main thing with pond and river water is that it is not stagnant, and your nose will know if it smells putrid or gross. Typically flowing water is preferred, because as it flows, oxygen is brought into the water which will reduce pathogens, but also pond water tends to be full of Purple Non-sulfur Bacteria which produce oxygen and will again reduce pathogens. Purple Bacteria are also useful in KNF context.
Main thing is the water is not stinky. If it is, aerating it through stirring, vortexing or bubbling for several hours can tremendously improve the condition of the water and make the water more conducive to the type of biology that we want to cultivate in KNF.

- KNF is very forgiving. I use rain water for brewing most of the year but at the end of summer bore water (of not the best quality ) has to suffice. We have no town supply of water. I use buckets of green murky water when making soil mixes in my cement mixer. My mineral deficient soil (white sand) that is between 800 and 125 thousand years old benefits from any microbial content.
