Indian Head Naval Surface Warfare Center (NSWC) provides
services in energetics for all warfare centers, including
engineering, fleet and operational support, manufacturing
technology, limited production, and industrial base support. It
produces and handles complex chemicals to accomplish this
mission. Lead, silver, and mercury are the primary
contaminants of concern. A technical review committee was
formed in FY93 and converted to a Restoration Advisory Board
in FY95. The installation was placed on the NPL in February
1995. In 2005, the BRAC Commission recommended Indian
Head NSWC for realignment. The installation prepared a
community relations plan and established an information
repository. The site management plan has been developed and
updated. In FY98, the administrative record was converted to
an electronic format, which is updated periodically. A federal
facility agreement (FFA) was completed in FY01. The Indian
Head Installation Restoration (IR) partnering team meets
approximately 10 times a year and has been highly successful
in facilitating agreements between the Navy and regulators.
The installation has identified 61 IR and 28 Military Munitions
Response Program (MMRP) sites. Records of Decision (RODs)
have been completed for 7 sites and no further action (NFA)
RODs, or equivalent decision document (DD) for 26 sites. The
cleanup progress at Indian Head NSWC for FY02 through FY05
is detailed below.
In FY02, the installation completed the desktop audit of 28 FFA
areas of concern (AOCs). A DD recommended no action for 17
AOCs. The relative risk of Site 28 was re-evaluated following
sampling, moving it to the high-risk category and the installation
initiated a remedial investigation (RI). Removal actions for Sites
12 and 41 were started. The NFA ROD for Site 44 was signed.
The Navy completed an inventory of all MMRP sites. MMRP
sites were identified at this installation.
In FY03, the installation completed the removal action for Site
12. The NFA documents were signed for Sites 32, 34, 51, and
52. In addition, the pilot study using a hydrogen-reducing
compound was implemented at Site 57. The lessons learned for
Site 12 were compiled and included information on erosion
control measures and selection of fill material. The installation
developed a range inventory and created 24 new MMRP sites.

Additionally, the installation initiated preliminary assessments
(PAs) for all MMRP sites.
In FY04, the installation completed RIs for Sites 6, 11, 13, 17,
21, 25, 28, 39, 45, and 47. Indian Head NSWC began long-term
monitoring at Site 12, and completed a RI of the Lab Area,
which includes Sites 15, 16, 49, 50, 53, 54, and 55. It also
completed the Mattawoman Creek ecological risk assessment,
a feasibility study (FS), and remedial design for Site 42. The
Navy completed RODs for Sites 12, 13, and 25 and signed NFA
DDs for Sites 5, 40, and SWMU 74. The installation improved
techniques by using desktop evaluations for several sites to
reach decisions for NFA. The installation completed the draft
final PA reports for the Indian Head main facility and Stump
Neck Annex MMRP sites.
In FY05, Indian Head NSWC completed baseline ecological risk
assessments (BERA) for Sites 11, 17, and 47 and initiated
removal actions at Sites 17 and 42. The installation also
initiated site screening process (SSP) investigations for Sites 2,
3, 4, 7, 8, 9, 18, 19, 20, 23, 24, 26, 27, 33, 36, 38, 43, 46, 48,
and SWMUs 14 and 30. The installation completed
site-screening investigation fieldwork for Sites 2, 4, 7, 18, 23,
43, 36, and 38. The installation signed NFA DDs for Sites 3, 9,
20, 33, 39, 45, 46, 48, 58, 59, and 61, and RODs for Sites 39,
42, and 45. Site 24 was recommended to undergo an RI. Indian
Head NSWC completed PAs, site recommendations, site
prioritization, and cost analysis documents for MMRP sites.

Indian Head NSWC completed removal or remedial actions at
Sites 17, 42, and 57. The installation completed engineering
evaluations and cost analyses for Sites 6 and 28 and an FS for
Site 57. The Navy completed BERAs for Sites 28, 47, and the
Lab Area. The installation also initiated a bench-scale study for
Site 47. The installation completed SSP reports for Sites 2, 4, 7,
18, and 23, and signed a ROD for Site 42. The Navy also
signed NFA DDs for Sites 2, 4, 7, 18, and 23. The cost of
completing environmental restoration has changed significantly
due to regulatory issues.
Regulatory review delayed completion of removal actions at
Site 6. The installation is undergoing additional investigation

and regulatory review for Sites 1, 8, 19, 26, 27, 36, 38, 43, and
SWMUs 14 and 30 in order to complete SSP investigations.
Technical issues delayed the signing of RODs for Sites 11, 17,
and 21.

The installation restarted removal actions at Unexploded
Ordnance (UXO) 32, and completed Phase I (identification,
demilitarization, and disposal of scrap munitions items). The
Navy was unable to be complete the actions due to delays in
preparing an explosives safety submission.
