Researchers from the University of Texas at Austin and Navajo Nation, Tuba City Chapter (Tuba, AZ) have discovered that by combining pine tree resin and silver-based nanoparticles that are present in traditional pottery, they were able to create new water filtration solution for members of the Navajo Nation, many of which still have limited access to reliable sources of clean drinking water. This ceramic water filter creates an effective and inexpensive way to disinfect water simply by pouring water through the coated pottery. Accounting for materials and production, these pots could be made for less than $10 each.
