The
issue of lead paint, has been brought up regarding the Bicentennial
Mural. But what does the Army Corps May 2014 lead Survey have to
say about how much lead is actually in the mural?
To
start with, the White and Blue paints that make up the majority of
the 80,000 sq. foot mural, are in fact NOT lead based paints.
Though
the Red paint on the mural was found to be a lead based paint,
it was the Yellow graffiti underneath the mural, that actually
contained the highest level's. Per the Corps Survey, the yellow
paint is estimated to be less than 1,000 sq. feet.
Mural Showing Location of 1972 Graffiti
Prado Dam
Spillway in 1972
In 1972, the Yellow Cal Trans Paint, was
used to graffiti "72 Rules" on the Prado Dam Spillway (see photo
above). That same Cal Trans yellow paint was used to paint lines
on millions of miles of Southern California roadways. Since there
are already systems in place to pacify or specifically remove any lead
paint, this is not seen as an obstacle to restoration.
SOIL ANALYSIS: The soil analysis around the 39 year old mural indicates
that no soil sample was above the California Human Health Screening
Level of 80 mg/kg for shallow residential soils, and are within
background levels for California and Riverside (University of
California [UC] 1996).
