Scientists are studying how toxic chemicals are naturally degraded in polluted waters with a view to developing cost-effective methods for cleaning up contaminated sites.
Water pollution from industrial chemical plants has created nearly three million contaminated sites in Europe that need cleaning up. Common groundwater contaminants such as chloroform, carbon tetrachloride, trichloroethylene and tetrachloroethylene are particularly difficult to remove.
