Hi there Alexander. It’s a little further away, but officially the clearest water in the world is found in a place called Te Waikoropupu Springs (Pupu for short – rather an ironic name I know) in Nelson, New Zealand.
Here’s a couple of links for you to check them out:

Please let me know if you are interested on andy@galeforcefilms.com
My website, http://www.galeforcefilms.com is being relocated to a new server so is down at present, however I can provide a full resume via email in the interim.
Kind regards,
