determined that
special lasers
couldremove
the biofilm
without damaging
the marble.
These lasers–similar
to the ones used toremove
tattoos–reduced
the microbial gunk
to afine ash.
Finally,special ists went to
work withagentle,
low-volumesteam cleaning
to remove the ashresidue
and anyother dirtand grime
from the monument’s
marble surfaces.
When they
werefinished,
the Jefferson

Biofilm likely
began forming
on the Jefferson
Memorial’s
Vermont marble
almost as soon
as the building
wascompleted
in 1943.
Several factors
mayhavecaused
thebiofilm to
change:
■Natural
erosionof the
marble, givingthe
gunk morepits and
cracks in which to grow
and thicken
■Jet fuelfrom passing

■Moreultraviolet lightas
the city’sair got cleaner.
Whatever the cause, the film
began to darken, discoloring
the monument.

A
searly as 2015, anyone viewingthe
JeffersonMemorial fromadistance
—say,from IndependenceAvenue
acrossthe Tidal Basinoranaircraft
window on approach to ReaganNational
Airpor t—could see that something was
wrong .One of the capital’s signature monu-
ments, apriceless piece of thenation’s
heritage, was starting to look downright
shabby. Dark splotches were growing on the
iconicwhitedome.Growin gfast.
Faced wit hthe speed of changeand the
increasing number of visitors and residents
askin gwhatwasgoingonwiththememorial,
National Park Serviceanalysts concluded
theycouldn ’t fight whattheydidn’t fully
understand. They took apatientapproach,
calling in scientistsand their ownconser va-
tionexper ts an dembarking onayears-long

memorial’s now-78-year-oldmarbledome.
“Itwas maybe 15 yearsbetweenthe time

finallyactedonit, ”saidAudreyTepper,aPark

Theculprit, the yeventual ly determined,
was something thatprobably had been pre-
sentont he monument, and nearlyevery
other outdoorstructure in most cities, for
decades :biofilm.
“It’samicrobialcommunityofb acteria,
fungi and algae,”Tepper said. “Itoccurs all
overtheplace.It’s existedforeternity,butit ’s

It’s usuall ybarely visible, andinf actno
one knows for sure howlongit’sbeen
growing on theJefferson Memoria ldome. It

In collaboration with commercial restora-
tionexperts,Park Se rvice analystsdeter-

infestation was superficial. If it couldbe
cleaned off, it would leave the underlying
marbleundamaged.But ther ewas acatch.
“Mos tpeopleinthepreser vationindustryuse

cleaning agents pri marily developed for the
healthindustr yand the food industry,”said
Judy Jacob, National Park Service senior
