Pumpkin Power?

Well I have a question about the following. Maybe I'm not understanding this right, but if the pumpkins can draw out the DDT from the soil that's good right? Now they way they must check that is to find out how much DDT ends up in the pumpkin or whatever else they are using and then checking to see how much less DDT is in the actual soil that the pumpkin was growing in. Ideally, I guess, the pumpkin is packed with DDT and the soil is clean, right? OK so far, but my question is what do you do with this pumpkin? You can't eat it, you can't put it into your compost pile or you put the DDT back as well. So what do you do. That's my question.
NOW THAT'S A GREAT PUMPKIN, CHARLIE BROWN
Pumpkins found to absorb pesticides from soil

Pumpkins are not only good for jack-o'-lanterns, pie, and carrying Cinderella home -- they are also extremely effective at drawing persistent organic pollutants like the toxic pesticide DDT out of soil, according to a new study by Canadian researchers. They tested rye grass, tall fescue, alfalfa, zucchini, and pumpkins, but the oddly Halloween-specific orange gourd won by a large margin. While the Canucks acknowledged that phytoremediation -- the use of plants to clean contaminated sites -- will never fully replace more high-tech methods, they suggest that it offers a "green solution" that may work well in communities and countries where such technology is not available. Obviously, DDT-ridden pumpkins would not be used for pies or jack-o'-lanterns (unless some sicko just wasn't satisfied with razors in apples). Rather, they would be buried or incinerated.
