RESIDUAL EFFECTS: Army Digs Up Arsenic-Poisoned Ground in Spring Valley

The Washington Post reports this morning that the Army Corps of Engineers has started to dig up portions of the Upper Northwest neighborhood of Spring Valley to remove arsenic from properties that were found to have elevated levels of the poison.

The neighborhood, adjacent to American University, was built on land used for World War I-era chemical weapons testing. To learn more about the contamination, refer to my posting from Monday.
