Cesspool on the Potomac

Well, Lisa Simpson was wrong. The cesspool is the Potomac. A new report out says that the Potomac is growing more polluted. The culprits are development and combined storm drain-sewer systems--i.e., building more, laying more concrete and blacktop, with an increasingly inadequate infrastructure. Maybe this is a candidate for some of that stimulus?

Btw, the National Triathlon--those folks swam the Potomac. No thanks.
