Kiley Barrel Allen Street Site is comprised of 3 residential properties on Allen Street, Somerville, Middlesex County, MA, adjacent to the former drum rinsing operation known as the Kiley Barrel Site (currently a Brownsfield site). The site is in a minority Environmental Justice area.
The Site consists of 1 three-story and 2 two-story residential buildings. Elevated levels of arsenic (in some cases were as high as 400ppm) in the yards are believed to be due to surface runoff from the adjacent Kiley Barrel Site.
POTENITAL FOR CONTINUED STATE/LOCAL RESPONSE
The actions by EPA will be limited to a depth of 3 feet of the surface soil for Arsenic contamination. The MassDEP may be interested in contamination other than the Arsenic or at depths greater than three feet. It is believed that below a depth of three feet, the subsurface material consists of urban fill. This will be confirmed post excavation.
