Has anyone seen the study regarding growing switchgrass to improve water quality? Any thoughts?

I looked briefly at the study. The improved water qualityy applies to large watersheds, like that of the Mississipi, but how could it be applied in an urban settings? What benefits could we get? How could this apply?
Personally I think that it is a little too early to consider making a switch to growing biofuels. The goal in growing switchgrass is more to the fact that there is added feedstock, meaning that there is the potential for more contaminants coming through localized wastewater treatment systems. On the surface, the idea seems like a good one. More plants means more potentially harmful nutrients being taken out of the groundwater, which makes everyone's life a lot easier. Bioproducts from even a commercial standpoint aren't really viable right now, but maybe 5-10 years down the road? This could be an awesome way to improve local water quality.
