This Sign Says it All

One of the bloggers at Green Unlimited posted a photo of a sign that she saw hanging in her local pharmacy:

That's a pretty scary reminder of what is likely lurking in your tap water. Municipal water systems are equipped to remove these pharmaceutical contaminants from water. And filters don't do the job:

While it's possible, maybe even likely, that some of the home water-filtration devices will remove pharmaceutical compounds, there is not yet evidence proving it. Also, it's unlikely that one device or even a combination of them will reduce or eliminate every pharmaceutical compound that makes its way to your tap. There are tens of thousands of pharmaceutical compounds, and most of them have entree to public water systems through waste treatment.
