That’s right. Although the water is cleaned immediately, and you can drink it, the cloudiness, if it occurs, may not settle for a longer time. In fact, Biotite Concentrate can be used as a test for the purity of water. If you follow label directions and see no sediments occur, then you know the water you’re using is very clean. And the opposite is true too. If there’s a huge cloud in the water and it takes a long time to settle, then the water was filled with contaminants. We recently ran this test on a high quality spring water that is well known for it’s superior quality, even though over 25 years ago, the EPA stated that there was no longer any source of completely pure water in the continental US. We added an appropriate amount of Biotite Concentrate to this spring water, which came to us in a sealed glass bottle. 24 hours later there were bits of rusty sediment on the floor of the container. We haven’t had the sediment analyzed but this test suggests that even spring water can be contaminated.
