Friends of Sligo Creek recently signed on to this letter to the Maryland Department of the Environment (MDE) urging both MDE and DNR to add the Anacostia River and its tributaries (including Sligo Creek) to the state's impaired waters list, specifying trash as the pollutant of concern. Once the Anacostia watershed is listed, we can begin the process of developing a total maximum daily load (TMDL) for trash in the watershed,and enforceable actions to meet the TMDL. The letter,which includes the latest Anacostia Tributary Trash Survey, has great photos at the end.
