Fads and movements on what we do and don’t put in our bodies seem to plague the US and latest one has originated out of California.

There has been a huge demand in Silicon Valley for very expensive “raw water”. Raw water is supposedly unfiltered, untreated, unsterilized spring water according to a NY Times report.

The rationale is that the existing water supply and tap water has many chemicals and pollutants and naturally occurring minerals that are filtered out when water is treated.

What about this trendy fad and what are the health risks?
