LINE 2 AMMO LAP (ARTILLERY/SHAPED)-GROUNDWATER

 

Line 2 is a production line that has been in operation since the inception of IAAAP, except for a brief hiatus from 1947 to 1949 and occupies nearly 140 acres, including 31 buildings and covered walkways. It is used to load, assemble and pack 120mm ammunition and blank ammunition. The melt building appears to be where the highest volumes of wastes were produced. The buildings include equipment rooms, explosives magazines and nine sump buildings.

This IRP site consists of groundwater (GW) contamination from past munitions production.  Any contamination from current activities will be addressed under compliance [non-Environmental Restoration, Army (ER,A) funding].  The past contamination resulted from the practice of washing spilled explosives from floors and equipment and from spillages resulting from sump failures.

The PA/SI was completed in 1991, and an initial RI was completed in May 1996.  A Supplemental RI was completed in 2003 to fill groundwater data gaps found in the RI, dated May 1996.

This site was separated from IAAP-002 to better manage groundwater cleanup and allow clearer reporting for phase completions and funding allocation.

Phase progress will be tracked at the PBC Site, but funding requirements will be tracked under the PBC Site at Iowa.  Post PBC costs will be covered under Site IAAP-020.

CLEANUP STRATEGY

This site is included in the PBC awarded in 2004.  The remedial approach for this site, as well as others in the Brush Creek watershed, will be assessed in the feasibility study (FS).  At present, it is presumed that localized areas of contamination will be remediated.
