Researchers at Stanford have created a kind of inexpensive sensor based on carbon nanotubes (these things are so useful!) that can detect traces of TNT and the nerve agent Sarin in water. This can be useful to detect terrorist attacks on the water supply or leaching from munition making or storage facilities, but I bet this type of sensor could also be used to detect other kinds of toxins and help us track down polluters.
