According to Washington Post blog Going Out Gurus, Fort Reno Park, site of the long running annual summer concert series, is closed after the United States Geological Survey discovered high levels of arsenic in the soil. Snow fencing was apparently erected around the park’s perimeter early this morning. There’s no word yet regarding when the park will reopen or whether the concert series will take place at an alternate location.

Needless to say, this is a is pretty devastating blow for D.C. music culture.
