Precise Source of Lewisite in Soil Under Front Porch is Unknown

The analytical results for the liquid in the intact container discovered on Jan. 17 tested positive for lewisite.  The bottom layer of liquid in the bottle contained a small amount of lewisite ... There was no release of lewisite during the discovery or removal of the item.  With the results of the testing complete, the container will be properly disposed of by the Edgewood Chemical Transfer Facility.

 AUES bottle containing Lewisite

Until recently, the soil samples have been non-detect for chemical agents or industrial compounds.  A report received Jan. 31 showed that recently excavated soil tested positive for lewisite.  This soil came from the area around the location where we discovered the Jan. 17 intact glass bottle that also contained lewisite.  The soils currently being excavated are 6-8 feet below ground surface.

Army spokesperson Andrea Takash said the container found was not leaking and that she could not speculate on the source of the lewisite found in the soil.  Workers have removed countless pieces of glassware from the site.  The burial pit is believed to have been disturbed when the home at 4825 Glenbrook was constructed in the early 1990s, and construction workers building the house reportedly suffered injuries consistent with chemical weapons exposure.  Residents of the house also reported illnesses before moving out in 2001; the home was subsequently left vacant before it was demolished. 

     
At their meeting last Wednesday, several members of the Palisades/Spring Valley advisory neighborhood commission expressed concerns about the Army’s findings.  “Lewisite is nothing to fool around with.  It’s a very serious thing,” said commissioner Tom Smith, whose single-member district includes 4825 Glenbrook.  Smith said he was also worried that lewisite may have also contaminated neighboring properties — the American University president’s house and the South Korean ambassador’s residence.
