Lawrence--  Help us out here. What are the names of some grasses that are 
good for sequestering heavy metals? 

One fallow season growing these grasses and removing them, rather than 
turning them under, should clean up an urban garden and make it ready for veggies. 
The problem is what to do with the chaff. Take it to the landfill, if they will 
accept it, I suppose.
