From Multi-Pure: “We use food grade quality polypropylene for
our plastics. The NSF tests for this as well. We are certified by the
NSF. We do not add anything into the water from our Systems.”

They rinsed plastic and glass bottles, added water and snails, and waited. After a period of time, the snails housed in the plastic bottles generated significantly more baby snails than the ones in the glass bottles. This suggests that the plastic packaging is a source of active estrogen hormones.

The result of the extra estrogens, along with four other factors, is affecting a population of men who haven’t grown up, says Sax. He cites some interesting studies. One looks at men in the age group of 35 to 40. Normally, men this age are married. In fact, only 25 years ago, only 8 percent of American men in this age group had never married. But as of 2006 that 8 percent had nearly tripled. It was up to 22 percent and still rising rapidly. (He cites Eduardo Porter and Michelle O’Donnell, “Facing Middle Age with No Degree and No Wife,” New York Times, Aug. 6, 2006.)

The proportion of men aged 18-35 living at home with parents or relatives has doubled in the last 30 years. Meanwhile 36 percent of babies in the United States in 2004 were born to unmarried women. These statistics cut across all demographic groups.
