There is evidence that perchlorate is absorbed and concentrated by 
vegetable crops, and much research has been done on lettuce in areas 
downstream from Lockheed's plant.  Lockheed is cooperating with at least 
one major farm in trying to remediate the situation.  Just because 
perchlorate is very mobile in water does not necessarily mean that water 
is the major source for humans.  The scariest thing about perchlorate is 
that bioaccumulation occurs in commonly eaten plants.  Other 
contaminants such as DDT bioaccumulate mostly in animals.  This means 
that eating lower on the food chain is not safe in terms of perchlorate 
exposure.
