Burnt Mills is an census designated place in Montgomery County, Maryland, United States.

[4] The site of a grist mill that burned down before 1788, Burnt Mills became an important source of clean drinking water for Montgomery and Prince George's Counties in 1929 when the Washington Suburban Sanitary Commission (WSSC) built a water filtration plant here along the Northwest Branch Anacostia River near Silver Spring, Maryland.

[5] At the time of its construction in 1929, the water filtration plant at Burnt Mills was considered a landmark achievement by Robert B. Morse, chief engineer, and the WSSC, reflecting public awareness "of the importance of managed water systems to public health."

Its water filtration and pumping facilities were removed, but the two Georgian Revival buildings and the dam remain.

Southeast Hebrew was originally founded by Orthodox Eastern European immigrants in 1909 on Capitol Hill in Washington, D.C.
