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.

Manufacturers say they are moving to take BPA out of baby bottles. But the rest of us are at risk as well. The product not only leaches from soda and water bottles, but it lines metal cans and “microwaveable” packaging. BPA was originally developed as an estrogen replacement, according to Kissinger’s article, and is now found in the tissues of nearly every American tested.

So I ordered the under-sink model 750SB, at $340 after discount. Most householders won’t have too much trouble installing this, but we had a problem: the sink lip is covered with granite countertop. So it was necessary to drill through the granite. I am guessing that most granite countertops aren’t installed this way, but ours is.
