Project manager Dan Noble reported that he has been unable to gain access to a home in the 3700 block of Fordham Road, where he suspects there might be another burial pit of potentially dangerous chemicals ... Old photos of the site show a series of trenches in other areas that led to burial pits. There is also a 1918 aerial photo showing a scar on the ground that looks similar to scars where other buried munitions have been found. Noble said Army headquarters will make a decision as to whether to take legal action to gain admission to the property, depending on the danger it might pose to the neighbors and the general community ... Four readings taken at the site had arsenic counts greater than 20 parts per million -- the agreed-upon safe limit -- and "one as high as 107."

Identified as the Sedgwick Trench. The Army performed extensive field testing of chemical warfare agents such as mustard, phosgene, chloropicrin, and cyanogen chloride at this site. The Sedgwick Trench is comprised of circular trenches approximately 200 feet in diameter. Livens and 75 millimeter shells with agent were statically fired in the center of the circular trenches.
