Here's another example of "THERE'S CHEMICALS IN THERE, WE'RE ALL GONNA DIE!" stories that don't really put it into perspective (at least not clearly).
Study finds silent killers lurking in your garden hose
Why is everything always a shocker when compared to drinking water?Silent killer chemicals were found in a new study in 100 percent of the products tested
But the study found the water that sits in the hose contained four phthalate plasticizers that currently are banned in all children's products. The sitting water studied also contained bisphenal A, or BPA and lead.
Study test results showed bisphenal A, or BPA, levels from garden hoses were 20 times higher than what's considered safe in drinking water.
Other things just aren't used to such a volume as that. Soda, and other stuff I can understand because people use that as a substituted. But drinking from a hose?
So; you would have to drink from a hose quite a lot before you're overall exposure hits "drinking water safe" levels. (assuming your normal intake is below the limit)
And notice it said "sitting water".
How often would you drink that "yuck" before letting it run a bit?
