C'mon... let's get real... The waste water is treated and has been shown to create no problems, when used for irrigation, etc., to humans and animals. And let's eliminate the terminology "Artificial Snow". The product created by forcing cold water through a nozzle, at high speed, and mixing it with cold air is not artificial in any sense. It is "Machine Made Snow". The components are exactly the same as the "Natural Snow" that falls from the sky. The difference is that the amount of air and water is controllable. It is adjustable to allow "snow-making" in different conditions of weather and to how the "snow" is projected to be used. ( Base is normally denser as compared to the lighter fluff used to cosmetically enhance a surface. ) The "Machine Made Snow" also is much easier to groom with snow cats than natural snow and tends not to blow away or drift as natural snow does.
