Biological Growth and Commerical Cleaners

Biological Growth and Commerical Cleaners

NCPTT is moving forward with the second phase of a two-year study to evaluate the effectiveness of commercial chemical cleaners for the removal of biological growth and dirt from federally issued headstones located in national cemeteries across the nation. The work is performed in partnership with the National Cemetery Administration, Department of Veteran Affairs.

During phase one, headstones were tested for biological growth and cleaned with five test chemicals at five climatically and geographically diverse national cemeteries. Phase two begins the evaluation of effectiveness by identifying biological re-growth on stones.

Completion of this study is expected in the summer of 2007.
