What is a #Superfund site? Find out in the December issue of #NatGeo magazine.
For the story title #Wasteland @FritzPhotos #FritzHoffmann visited 12 #toxic waste sites that are on the Superfund National Priorities List. The #landscape photos were made from a 50 foot aerial boom lift. The elevated view provided a perspective that communicates scale and a sense of our place in the Superfund picture.
This photo was taken while on assignment at the #RockyMountainArsenal in #CommerceCity #Colorado during the annual #roundup of American #bison, which are now living there to aid in returning the land to natural prairie. The arsenal is now the #RockyMountainArsenalWildlifeRefuge

The U.S. Army manufactured chemical weapons at the arsenal in the 1940s. The manufacturing facilities were then leased to #ShellOil Co. for their production of pesticides. Production ceased in 1982 and remediation of the land began. The EPA listed the site on the #Superfund cleanup priority list in1987. Parts of the 27 mile site have since been delisted from Superfund.
Introduction of the bison to the site lands began in 2007 by the U.S. Department of Fish and Wildlife. Eventually the refuge will support 200 head of bison.The bison are rounded up in part to check them for exposure to toxins that may remain on the land.

Read the story on Superfund in the story titled #Wastelend in the December #NationalGeographic magazine, in the NatGeo iPad edition and at www.ngm.com.
