This morning, my friend Dr. Whisky sent me a link to what may possibly be the greatest BBC news story ever.

Researchers at the University of Aberdeen (shout-out to [profile] hermiston!) have discovered a way to use byproducts from the whisky industry to treat contaminated groundwater. This process, which has a name that has been tortured to produce the acronym DRAM, is still in the research stages. Hmmm, I wonder if anyone has properly studied the side effects on human populations exposed to DRAM via the ingestion pathway?

That same AP article (http://ap.google.com/article/ALeqM5hGsoyElv4ZL879LW6z2aZS0Pix7AD8VA14500) ran in the NYC papers this morning. Focus on the units: they found drugs in concentrations of parts per billion & parts per trillion.

I spoke to a chemist from one of our laboratories a few weeks ago about a particular analysis for mercury that is accurate to parts per trillion. He said that, in order to run that test without interference, they had to hire a chemist who had no mercury fillings in his teeth. That's how sensitive a parts per trillion assay is.

Personally, I am not concerned about drugs being detected in my drinking water at such low concentrations. I think it says more about the advanced state of our detection technology than it does about any risk to public health.
