I already drink recycled water.  On average, each glass of water I drink has been through seven other human's kidneys, and been through a processing plant each time. There may be measurable quantities of all sorts of 'stuff' in there, but having water to drink is better than not having enough, and the limits on pesticides, heavy metals etc. are low enough for them not to be a concern.  Natural water (of any kind) is radioactive due to the tritium (natural abundance in groundwater between approx. 100,000 and 3,000,000 atoms per gram, with a half-life of  12.32 years).  Shock! If you were to drink 'natural' groundwater, just hope the bacterial load is not too high, and you don't live in Bangladesh (arsenic contamination of the groundwater is a big problem there).  Treated water, even if recycled, is excellent - and far better than what most of the world's population are forced to drink.  My vote is that Mr Berghofer is playing on people's fears and ignorance.
