The Scripps Howard Foundation announced today that the Washington Post‘s online investigation, Fixing D.C. Schools, is the winner of its National Journalism Award, web reporting category. WPNI gets a sweet trophy, $10,000, and the satisfaction of beating out the also-rans: Roanoke.com’s coverage of the Tech shootings and WSJ.com’s comprehensive take on the subprime mortgage fiasco.

The Post‘s Anne Hull and Dana Priest were finalists in the public service reporting category for their series on the Walter Reed Medical Center, which has serious Pulitzer buzz. The winner in that category? The Chicago Tribune‘s excellent investigation of another fiasco this year: the recall of toxic toys.

D.C. media racked up another win from a more suprising contender: WJLA-TV. The station received the top prize in Excellence in Electronic Media TV-Cable and the Jack R. Howard award for “Drilling for Dollars,” a five-month investigation into greedy dentists at Medicaid clinics, which resulted in the shutdown of two Small Smiles shops, one in D.C. and one in Langley Park, Md. Go I-Team!
