During its restoration of the 168 Benjamin Latrobe designed sandstone cenotaphs, the National Park Service chose D/2 to do the cleaning.
On the National Register of Historic Places, Burial Hill in Plymouth, MA, is one of the oldest European cemeteries in America. Many of the original Mayflower Pilgrims are buried here including the first governor, William Bradford and Church Elder, William Brewster.
The project will span four years to be completed prior to the 400th Anniversary in 2020. The work includes conservation and cleaning of more than 2,269 historic stones. D/2 Biological Solution is the specified cleaner.
Stone conservator Ivan Myjer wrote the specification. Monument Conservation Collaborative (MCC) has been engaged to complete the work. A.H. Harris is the D/2 supplier. The Friends of Burial Hill raised the funds for the project through a Plymouth Community Preservation Commission Grant
