First time on the listserve, ya¹ll. I do the newsletter of the U.S. Biochar Initiative. In the December 2011 edition there was a drinking water biochar purification study from the University of Colorado. There¹s a diagram of the system on a poster we linked to. Next, below, is a link to the Dec. 2011 edition in the archive, followed by a link to the poster.
