For the Documerica Project (1971-1977),
the Environmental Protection Agency
(EPA) hired freelance photographers to
capture images relating to environmental
problems, EPA activities, and everyday
life in the 1970s.
The U.S. National Archives digitized more than 15,000 photographs from the series, and they can now be seen online. 
 Marc St. Gil was one of nearly one
hundred photographers hired for
DOCUMERICA. His assignment was to
document the water and air pollution
crisis in and around Houston, Texas.
While documenting the apparent
pollution issues, St. Gil also captured
striking images of rural life in 1970s
in the Houston and San Antonio areas.
