D.C.'s historic Anacostia River is sick.  Years of development, urban pollution, and runoff have caused alarming buildups of contaminated sediment.  Aquatic life is endangered and advisories warn against eating the river's fish.  Standard treatments include digging out the settled toxins, but dredging is expensive and risks stirring up the Anacostia's poisons.  Danny Reible, a Texas engineering professor, thinks the solution might be to physically seal off toxic areas of the river bed, using materials that also actively degrade or control the pollutants.  Reible's now directing field work by a D.C. firm, Horne Engineering, to test these methods for restoring the Anacostia's health.  With the National Academy of Engineering, Randy Atkins, WTOP Radio.
