CENTRAL TEST AREA

 

SITE DESCRIPTION

The Central Test Area consists of 31 acres (increased from 15.16 acres) located in the north-central portion of the IAAP within the Line 5 IRP site boundary. It is currently undeveloped. Line 5 is identified as AEDB-R site number IAAP-006. This test area was used from 1943 through 1963 for testing hand grenades, landmines and adapter boosters. A test pit and tripod were located in this area. The test pit had an earthen floor surrounded by wooden walls covered by steel plates. A concrete stand was located in the pit. The tripod area consists of a metal triangular stand, which was used to hold components to be test detonated. Limited information is available about the operations that took place in the central test area. No known UXO responses have been conducted at this site.

In the fall of 2004 MKM Engineers, Inc. performed a geophysical density survey for MEC at the Central Test Area. The MEC density survey was performed using an electromagnetic metal detector to a depth of four feet below ground surface. MEC construction support is recommended for the two identified concentrated areas prior to performing any intrusive activity. For all other areas at this site, avoidance procedures should be used during any sampling and clearance is required prior to any large scale soil removal.

CLEANUP STRATEGY

In October 2007 the SI was completed. Per the agreements made in the December 2006 dispute resolution, the US Army has agreed to complete RIs at all MMRP sites at IAAAP. The RI began in April 2008. The munitions response site (MRS) Prioritization Protocol score for this site was reviewed in FY09.
