Question: is the home tap water filtration issue addressed vis-a-vis it's effectiveness in the removal of arsenic from the municipal water supply? I know our tap water tastes like an alligator took a whiz in it (which isn't too far from the truth), so I can only imagine what else is in it, even after being processed by the local plant. We currently use two pitchers (one Brita, one Pur), for most kitchen uses. I'd like to know if that's doing anything else but making the water taste better.Go to the original article. At the bottom, the last section is called "Sidebar: Ways to reduce your familys risk." There's an EPA link about testing water and a "federal Safe Drinking Water Hotline at 800-426-4791."
