Site EO093 OB/OD-Impact/Target Areas QA Panel Report

Former Adak Naval Complex Adak, Alaska - April 2008

Sites are potentially contaminated with MEC primarily from past use of the property as a staging area for the retaking of Kiska and Attu from Japanese occupation forces during WWII era. There are 155 OU B-1 sites, but only 4 sites have further action [Lake Jean LJ-01, Mount Moffet (MM) (MM-10F, MM-10G and MM-H)], for a total of about 370 acres. There are 24 OU B-2 sites - 18 with further action. Total area of OU B-2 sites with further action is about 1,500. A remedial investigation to fill data gaps is anticipated for 2008. ROD anticipated in 2010 or 2011. Remedial action complete is anticipated by 2016.

Final Technical Memorandum Evaluation of Adak Island Blue Mussel and Rock Sole Tissue 2007

Former Naval Complex, Adak Island, Alaska - November 2007

This technical memorandum (letter report) provides an evaluation of polychlorinated biphenyl (PCB) concentrations in rock sole (Lepidopsetta bilineata) and blue mussel (Mytilus edulis) specimens collected from Sweeper Cove and Kuluk Bay at Adak Island, Alaska in 2007 and concentrations found during previous biological sampling efforts performed from 1999 through 2005. The report summarizes the field sampling program conducted in June 2007 to obtain the required biological samples, including the procedures used to collect and process samples and the methodologies used to analyze those samples.

The primary conclusions drawn from the evaluation of the tissue data collected from 1999 through 2007 are that (1) mean total PCB concentrations in rock sole from Sweeper Cove and Kuluk Bay increased between 2005 and 2007 after a drop in the period between 2003 and 2005, (2) mean total PCB concentrations in rock sole from Sweeper Cove and Kuluk Bay exceed the risk-based action level (RBAL) of 6.5 micrograms per kilogram (µg/kg), (3) mean total PCB concentrations in blue mussels from Sweeper Cove and Kuluk Bay decreased between 2005 and 2007, (4) mean total PCB concentration in blue mussels collected in 2007 from Kuluk Bay is below the RBAL of 31 µg/kg, and (5) mean total PCB concentration in blue mussels collected in 2007 from Sweeper Cove is above the RBAL and was affected by localized areas of relatively higher concentrations. Four samples had PCB concentrations below the RBAL, and one sample had levels significantly higher. SES-TECH recommends that the Navy maintain current fish consumption advisories (fish here is taken to mean both fish and shellfish). Current fishing advisories are in place for rock sole and blue mussel from Sweeper Cove and rock sole from Kuluk Bay.

Final Landfill Annual Monitoring Report, September 2006, OU A

Former Naval Complex, Adak Island, Alaska - June 2006

The monitoring event was performed in accordance with the Comprehensive Monitoring Plan (CMP), Revision 2 (Navy 2005b), and completed in September 2006. Monitoring results were compared to endpoint criteria established in Appendix F of the CMP and background concentrations established for inorganic analytes in sediment and groundwater on Adak Island. Based on the 2006 and historical sampling results, the Navy does not recommend any changes in the sampling of sediments at the Palisades Landfill, in the sampling at the White Alice Landfill, or in the sampling of surface water and groundwater at the Roberts Landfill. Based on low detections of target and non-target analytes, the Navy recommends that surface water sampling at the Palisades Landfill for TIN and DIN be reduced to once every other year with the next scheduled sampling event to occur in 2008. Because arsenic and barium have remained stable and below endpoint criteria at Metals Landfill, the Navy recommends that sampling for arsenic and barium be reduced to once every other year with the next sampling scheduled in 2008. The Navy does not recommend any changes in SVOC and VOC monitoring at the Metals Landfill. Well MW-603 should continue to be monitored during sampling events for discrepancy in total depth readings with prior year measurements.

Final Annual Groundwater Monitoring Report, September 2006, OU A

Former Naval Complex, Adak Island, Alaska - June 2007

The groundwater monitoring at Operable Unit A (OU A) of the Former Naval Complex, Adak, Alaska, was conducted in fall 2006. The monitoring program for 2006 was implemented as described in the Comprehensive Monitoring Plan (CMP), Revision 2 (U.S. Navy [Navy] 2005a), and the Draft Technical Memorandums for South of Runway 18-36, Naval Mobile Construction Battalion (NMCB) and Solid Waste Management Unit (SWMU) 62. During the monitoring event, groundwater samples were collected from 124 monitoring locations at 24 sites. Monitoring was conducted to satisfy OU A Record of Decision (Navy, Alaska Department of Environmental Conservation [DEC], and U.S. Environmental Protection Agency [EPA] 2000) remedy requirements and post-free-product recovery remedy requirements established under the State-Adak Environmental Restoration Agreement (Navy and Alaska DEC 2005). The types of remedies for which monitoring was conducted were monitored natural attenuation (MNA), limited groundwater monitoring, surface water protection, and compliance.

Based on the 2004 monitoring results, the MNA remedies appear to be effective. Results of natural attenuation parameter (NAP) monitoring indicate that varying degrees of anaerobic degradation is occurring at all of the MNA sites. Overall, 1999 through 2004 monitoring data provide ample evidence that natural attenuation is occurring at the monitored sites (Navy 2005b). A general recommendation was a reduction in monitoring for NAPs from annually to every 5 years, with the next NAP monitoring planned for 2009. The exception would be the collection of NAPs at the downtown (well E-701) and remote site (well 12- 802) background locations. Annual collection of these parameters at the background locations will provide a measure of the variability of these parameters over time outside of the influence of the chemically impacted areas. NAPs were also performed at SWMU 62 as a one time event and in the future will be scheduled with the rest of the sites.

Changes to the monitoring program, based on CMP endpoint criteria, have been agreed to at the Former Power Plant Building, GCI, Arctic Acres, NORPAC Hill Seep, Runway 5-23 Avgas Valve Pit, SA 78, SA 79, SA 80, SA 82, SWMU 14, SWMU 15, SWMU 17, SWMU 58/SA 73, SWMU 60, SWMU 61, and Yakatat Hangar.

2006 Institutional Controls Primary Site Inspection Report, Operable Unit A

Former Naval Complex, Adak Island, Alaska - February 2007

The United States Navy (Navy) is the lead agency, and the responsible party, for monitoring and ensuring the effectiveness of the institutional controls (ICs) selected in the Operable Unit (OU) A Record of Decision (ROD) at the former Naval Complex, Adak, Alaska. The Navy is required to verify that ICs remain effective and reliable for as long as the ICs remain in effect.

It is recommended that primary site inspections at all sites continue on an annual basis, as outlined in the ICMP.

Based on the findings of the September 2006 primary site inspections the following recommendations are made:

• An excavation prohibition sign should be posted on the road leading up to SWMU 67, White Alice PCB Spill Site.
• The sign on the south side of SWMU 11, Palisades Landfill needs to be replaced due to wind damage.
• The Excavation Notification request process should be reviewed for improvements to help ensure that excavation does not take place without Navy approval.
• The annual surveys have been conducted in accordance with the ICMP which primarily focus on the community’s knowledge of the ICs and their knowledge of the education tools. It is becoming apparent that there are an increasing number of visitors to the island such as bird watchers, commercial and sport fishermen, and hunters. The Navy should endeavor to increase the number of these visitors surveyed annually.
• While the Ordnance Awareness Education Program appears to be working fairly well for island residents, there could be some improvements that would help visitors and new and part time residents. The Navy should consider the recommendations listed in section 5.2 to help improve the Ordnance Awareness Education Program.

Final Second Five-Year Review of Records of Decision, December 2006

Former Adak Naval Complex, Adak Island, Alaska

The purpose of this 5-year review is to ensure that the remedial actions selected in the Records of Decision (RODs) for OU A and OU B-1 at Adak remain protective of human health and the environment. This 5-year review evaluates data collected at the site from May 2001 through September 2005. The protectiveness of the remedies for the OU A sites is discussed in this report by grouping the sites into categories of protectiveness. Most of the 178 OU A sites fall into the categories of either “remedy is complete and protective,” or “remedy is operating and is expected to be protective.”

The remedies for six of the OU A sites are concluded to be “not complete, but expected to be protective.” These six sites are:

• ASR-8 Facility
• SA 77, Fuels Facility Refueling Dock, Small Drums Storage Area
• NMCB Building T-1416 Expanded Area
• South of Runway 18-36 Area
• SWMU 17, Power Plant 3
• SWMU 62, New Housing Fuel Leak

Three of the OU A sites require follow-up actions to ensure the future protectiveness of the final remedy. These three sites are:

• NORPAC Hill Seep Area
• SA 88, P-70 Energy Generator, UST 10578
• SWMU 61, Tank Farm

The remedy for OU B-1 is expected to be protective of human health and the environment upon completion. The future remedy for OU B-2 is expected to be protective when selected and implemented. OU B-2 is in the remedial investigation/feasibility study stage, and munitions and explosives of concern (MEC) may be present.

Final Annual Groundwater Monitoring Report, September 2005, OU A

Former Naval Complex, Adak Island, Alaska - May 2006

Groundwater monitoring was conducted at Operable Unit A (OU A) of the former Adak Naval Complex, Adak Island, Alaska, in the fall of 2005. The monitoring program for 2005 was implemented as described in the Comprehensive Monitoring Plan (CMP), Revision 2 (U.S. Navy 2005a). The 2005 monitoring activities occurred from September 8 through 26, 2005. During the monitoring event, groundwater samples were collected from 84 monitoring locations at 23 sites for CMP purposes. Monitoring was conducted to satisfy OU A Record of Decision (U.S. Navy, Alaska DEC, and USEPA 2000) remedy requirements and post-free-product recovery remedy requirements established un the State-Adak Environmental Restoration Agreement (U.S. Navy and Alaska DEC 2005). The types of remedies for which monitoring was conducted were monitored natural attenuation (MNA), limited groundwater monitoring, surface water protection, and compliance. Results of natural attenuation parameter (NAP) monitoring indicate that varying degrees of anaerobic degradation is occurring at all of the MNA sites. Based on the 2004 monitoring results, the MNA remedies appear to be effective.

Based on the 2005 monitoring program results, recommended changes in site-specific monitoring for 2006 are as follows:

• Collect additional sample at GCI to check for an upgradient source; collect sample from well 12-702 at SA 78, P-70 Energy Generator to check distribution of dissolved constituents;
• Visually inspect surface downgradient of NORPAC Hill Seep for sheen;
• Reduce frequency of monitoring at Runway 5-23 Avgas Valve Pit;
• Discontinuation of monitoring of BEHP, MEC, PCE, and PCE daughter-products at SWMU 14, Old Pesticide Disposal Area; BEHP at SWMU 17, Power Plant No.3; and BEHP and MEC at SWMU 55, Public Works Transportation Department Waste Storage Area;
• Monitor BTEX at ROICC Contractor's Area, UST ROICC-7;
• Continue annual monitoring at remaining sites.

Final Landfill Annual Monitoring Report, September 2005, OU A

Former Naval Complex, Adak Island, Alaska - May 2006

This document has been prepared under contract with Naval Facilities Engineering Command Northwest (NAVFAC NW) for the 2005 monitoring at three landfills (Metals, Palisades, and Roberts Landfills) located at the former Adak Naval Complex, Adak Island, Alaska. The White Alice Landfill was not scheduled for monitoring in 2005. Based on the 2005 sampling results, the Navy recommends that sampling of sediments for SVOCs, TIN, TOC, and grain size be continued at the Palisades Landfill, in accordance with the CMP, Revision 2 (U.S. Navy 2005b); PCB analyses will be performed on samples collected in 2006. Based on the September 2005 sampling results, it is recommended that sampling be continued at the Metals Landfill for total arsenic and barium and dissolved arsenic and barium, because of the exceedances of Adak background concentrations. SVOC and VOC analyses will be performed on samples collected in 2006 at the Metals Landfill.

The Navy recommends that surface water and groundwater monitoring for VOCs be continued on an annual basis at Roberts Landfill, because only three years of post-closure monitoring data have been collected. Based on 2001 through 2005 sampling results for surface water and groundwater samples collected at Roberts Landfill, the Navy recommends that surface water and groundwater monitoring for inorganics continue on an annual basis because of the exceedances of the endpoint criterion for copper in surface water, exceedances of copper background concentrations in groundwater, and exceedances of endpoint criteria for three inorganics in groundwater.

Decision Document, South of Runway 18-36 Area

Former Adak Naval Complex, Adak Island, Alaska - August 2006

This decision document (DD) presents the selected cleanup alternative and the supporting rationale for cleanup of the South of Runway 18-36 Area at the former Adak Naval Complex, Adak Island, Alaska. Alternative 2 – Institutional Controls, Free-Product Recovery and Containment, Monitored Natural Attenuation (MNA) for Groundwater, and Natural Recovery for Surface Water and Sediment – is selected as the remedial alternative for the South of Runway 18-36 Area. The selected cleanup alternative, Alternative 2, consists of institutional controls for soil, groundwater, surface water, and sediment; passive free-phase product containment and recovery; MNA for groundwater; and natural recovery for surface water and sediment. One free-product collection/containment trench will be installed to prevent migration of free-phase product to surface water, thus eliminating the source of the sheen to one area of South Sweeper Creek. The existing free-product interception device adjacent to Transit Bridge will continue to be used to control sheen in that area. Sorbent booms will be used as an interim measure to reduce surface water sheen in South Sweeper Creek until the free-product collection/containment trench effectively eliminates the source of the sheen to South Sweeper Creek. Sorbent booms will also be used in West Canal to control sheen until free-product recovery activities eliminate free-product migration to surface water. In addition, seven new wells will be installed, and free-phase product will be removed from site wells using passive skimmers and sorbent socks. Institutional controls will be used to protect human health and the environment until groundwater no longer exceeds Alaska DEC groundwater cleanup levels, surface water and sediment no longer exceed the ecological RBSCs, and surface water no longer exceeds the Alaska DEC water quality standards for sheen, TAqH, and TAH.

This decision document (DD) presents the selected cleanup alternative and the supporting rationale for cleanup of the Solid Waste Management Unit (SWMU) 62, New Housing Fuel Leak site at the former Adak Naval Complex, Adak Island, Alaska. Alternative 2–Institutional Controls, Free-Product Containment and Passive Recovery, Surface Soil Excavation, and Monitored Natural Attenuation (MNA) for Groundwater – is selected as the remedial alternative for the SWMU 62, New Housing Fuel Leak site. A free-product collection/containment trench will be installed to prevent migration of free-phase product to surface water, thus eliminating the source of the sheen to East Canal. Sorbent booms will be used as an interim measure to reduce surface water sheen on East Canal until the free-product collection/containment trench effectively eliminates the source of the sheen. Four new wells will be installed, and free-phase product will be removed from the new wells and existing site wells using automated passive skimmers, passive skimmers, or sorbent socks. Surface soil in Sandy Cove Housing 102, 107, and 146 Area with DRO concentrations exceeding the ACLs will be excavated and treated. Petroleum concentrations in groundwater will be reduced through natural attenuation. Finally, institutional controls will be used to protect human health and the environment until groundwater no longer exceeds Alaska DEC groundwater cleanup levels and surface water no longer exceeds the Alaska DEC Water Quality Standard for sheen.

Proposed Plan for SWMU 17, Power Plant No. 3 Area

Former Adak Naval Complex, Adak Island, Alaska - August 2006

This Proposed Plan proposes the preferred cleanup alternative for SWMU 17. Cleanup activities that have already been implemented at the SWMU 17, Power Plant No.3 Area include AST cleaning and closures, contaminated soil excavation, free-product removals, oil/water separator removals, waste oil pond and retention pond sediment removals, fill placement near Amulet Way to prevent fuel seeps, and natural attenuation monitoring. The preferred cleanup alternative for SWMU 17, Power Plant No.3 Area is Alternative 3, MNA and Institutional Controls. Alternative 3 is selected for this site because groundwater concentrations are above the Alaska DEC cleanup levels. MNA is needed to reduce concentrations to below the Alaska DEC cleanup levels and institutional controls are needed as long as concentrations are above Alaska DEC cleanup levels. Therefore, Alternative 3 is protective of human health and the environment and complies with Alaska regulations.

Engineering Evaluation/Cost Analysis Report Rifle Grenade Range (RG-01)

Former Naval Air Facility, Adak Island, Alaska - July 2006

As a result of past United States Navy (U.S. Navy) use of the former Rifle Grenade Range (RG-01), munitions and explosives of concern (MEC) may be present at the site and may constitute an explosive safety risk to the public, site personnel, and the environment. Because of the high potential hazard associated with the MEC known to exist at this project site, the U.S. Navy has elected to accelerate the response action for this installation in advance of completion of a Record of Decision (ROD) for all Operable Unit B-2 (OU B-2) sites, beginning with the MRS RG-01 site. Five alternatives were evaluated using the type, quantity, location, and depth of MEC and MD; past, current, and future land use; and input from local agencies, stakeholders, and the community. Alternative 2, Institutional Controls, was considered an appropriate alternative, but as a stand-alone alternative it does not satisfactorily address the long-term risk and may not be acceptable to the stakeholders. Alternative 4, Surface and Subsurface Removal of MEC and MD, was considered an appropriate response action. Alternative 4 supplemented with Alternative 2 are recommended as this combination represents the most appropriate response for RG-01. Institutional Controls, including Recurring Review programs for the formal Adak Naval Complex have already been established, are currently active, and will continue after the MEC removal actions are completed.

Annual Groundwater Monitoring Report

Operable Unit A, Former Adak Naval Complex - September 2004

Groundwater monitoring was conducted at the Operable Unit A (OU A) of the Former Adak Naval Complex, Adak Island, Alaska in the fall of 2004. The 2004 monitoring activities occurred from September 12 through September 28. During the monitoring event, groundwater samples were collected from 56 monitoring locations at 22 sites for CMP purposes. Groundwater samples were collected from additional locations at select sites to support post-free-product recovery remedy evaluation. Monitoring was conducted to satisfy OU A Record of Decision (ROD) remedy requirements. Results of natural attenuation parameter (NAP) monitoring indicate that varying degrees of anaerobic degradation is occurring at all of the MNA sites. Based on the 2004 monitoring results, the MNA remedies appear to be effective. (Posted 06/05)

Monitoring the Natural Attenuation of Petroleum in Groundwater at the Former Naval Complex, Operable Unit A

Adak Island, Alaska - May and June 2003

During May and June 2003, the U.S.Geological Survey (USGS) installed monitoring wells and collected data to characterize the effectiveness of natural attenuation processes for remediating petroleum-contaminated ground water at Operable Unit A of the former Naval complex on Adak Island, Alaska. Evidence for petroleum biodegradation in ground water was evaluated at 10 sites, plans for future natural attenuation monitoring were suggested for those sites, and the natural attenuation monitoring strategy for all petroleum sites in the Downtown area of Adak Island was reviewed and refinements were suggested. Achieving the ROD specified final monitoring objective of estimating the rate of natural attenuation to demonstrate achievement of cleanup levels within 75 years will be problematic. Demonstrating (predicting) achievement of cleanup levels within any timeframe in a technically defensible manner will be difficult to achieve using any type of short-term monitoring and evaluation, and will be particularly difficult to achieve through monitoring and evaluation of dissolved-phase petroleum only. Despite the difficulties in demonstrating (predicting) achievement of cleanup levels within any timeframe in a technically defensible manner, natural attenuation processes appear to have greatly limited the extent of ground-water contamination at most sites investigated and have limited the risk that petroleum contaminants pose to downgradient receptors.

This report summarizes the results of lead and copper testing of drinking water on Adak between 1993 and 2002 and a corrosion control study conducted in 2000 to evaluate the effectiveness of installing a source treatment system. The corrosion control study reported that by introducting calcium phosphate into the drinking system, lead levels could be lowered by 80 percent. In addition, the data from the study indicated that replacing faucets would be slightly more effective in reducing concentrations of lead and copper than source treatment. Lead and copper levels would still be above regulatory limits. (Posted 09/02)
