One of the marvels of the modern world is the faucet. For as long as anybody can remember, you walk over to your faucet, turn it on, and out comes clean fresh water.
But it's not like this for many parts of the world, and we are lucky in the United States because we have dependable clean water. We are also lucky right here in California because with all of the droughts over the years, and some of them have been severe and long lasting, we have never had a truly severe water crisis. In other words, we have never had a situation for a large populated area where you go to the tap, and nothing comes out.
This time could be different because the entire system is getting stressed from top to bottom and the extreme dry, and warm years have put us in a place we simply haven't been before. The snow pack was essentially non-existent this year as was the crucial spring melt that can add a third or more of our water supply for the summer.
