Narrator: This is Science Today. Microbial proteins growing on timbers at the base of a flooded, abandoned mine has been found to clean up polluted water by removing sulfate and at the same time, taking out the heavy metals excreted from the abandoned mines. Physicist Peter Weber of the Lawrence Livermore National Laboratory was one of the authors of the study.
Weber: This is research that's being driven by the Department of Energy's need for developing new technologies for cleaning up water. So, this is research that we're looking specifically at abandoned mine sites and looking at the acid mine drainage issues - the pollution coming from these mines from subsurface waters into surface waters.
Narrator: The researchers want to understand how the material behaves in the environment.
Weber: How we can control that in the environment, enables us to do our cutting edge nanotechnology research knowing that we have the capability downstream to protect the environment, to protect the public.
