The NASA Lewis Research Center in Cleveland, Ohio, has developed a polymer material that removes toxic metals from contaminated water in laboratory tests. Since the material can be made into many forms, it can be used to purify water anywhere, be it in waste water treatment systems, lakes and ponds, industrial plants, or homes. The Environmental Protection Agency's limit for this metal is 3.38 ppm.
Additional tests show that the polymer is easy, inexpensive and safe to handle.
It is also strong, flexible, and chemically stable in storage.
