Historical operations at Lakehurst Naval Air Engineering Station<br />
(NAES) involved handling, storage, and onsite disposal of<br />
hazardous substances. EPA placed the installation on the NPL<br />
in July 1987, and the Navy signed a federal facility agreement<br />
(FFA) in October 1989. In FY01 and FY06, the installation<br />
completed 5-year reviews.<br />
To date, 45 potentially contaminated sites have been identified.<br />
As of FY99, the installation has completed Records of Decision<br />
for all sites. The cleanup progress at Lakehurst NAES for FY02<br />
through FY05 is detailed below.<br />
In FY02, the evaluation of oxygen release compound (ORC)<br />
injected at Sites 13, 16, 17, and 32 was completed. The initial<br />
round of ORC injection was not effective in reducing<br />
groundwater contaminant levels to meet applicable or relevant<br />
and appropriate requirements. The Navy completed an<br />
inventory of all Military Munitions Response Program (MMRP)<br />
sites. Six MMRP sites were identified at this installation.<br />
In FY03, the installation continued operation and maintenance<br />
(O&M), monitoring, data interpretation, and reporting for three<br />
pump-and-treat systems, four soil vapor extraction<br />
(SVE)/bioventing/sparge systems, six spray aeration systems,<br />
and one natural restoration site. The installation began using<br />
bimetallic nanoscale particles (BNP) to treat areas of higher<br />
level groundwater contamination in Areas I and J. The<br />
installation submitted a list of ranges at Lakehurst NAES to be<br />
addressed under the MMRP. A preliminary site survey,<br />
conceptual models, and draft preliminary assessments (PAs)<br />
have been completed for these ranges.<br />
In FY04, the installation obtained a no further action<br />
determination for Site 28, which was included in the<br />
construction completion report for Lakehurst NAES. The<br />
installation also completed nanoscale particle treatment of<br />
higher level groundwater contamination in Areas I and J (in<br />
addition to natural restoration) to demonstrate that all remedies<br />
are operating properly and successfully, and continued with the<br />
NPL construction completion process. Lakehurst NAES added<br />
a sparge well and thermal oxidizer to the existing soil vapor<br />
treatment system at Site 13 and reduced sampling<br />

requirements for three existing pump-and-treat systems. The<br />
installation completed the draft final PAs for four sites.<br />
In FY05, Lakehurst NAES conducted treatability testing of in<br />
situ chemical oxidation for treatment of groundwater at Site 16.<br />
The installation continued O&M, monitoring, data interpretation,<br />
and reporting for three pump-and-treat systems, four<br />
SVE/bioventing/sparge systems, six spray irrigation systems,<br />
and one natural restoration site. Lakehurst NAES distributed<br />
draft final PAs to regulators for review and comment. The<br />
installation conducted data collection, a site visit, and prepared<br />
a PA for the Lakehurst Proving Grounds.<br />

Lakehurst NAES completed a 5-year review of the remaining<br />
sites. The facility expanded the BNP treatment of groundwater<br />
in Areas I and J and completed a specification for the<br />
expansion of treatment systems at Sites 10, 13, 16, 17, and 32.<br />
The installation continued O&M, monitoring, data interpretation,<br />
and reporting for three pump-and-treat systems, four<br />
SVE/bioventing/sparge systems, six spray aeration systems,<br />
and one natural restoration site.<br />
