This work plan describes the following sampling activities planned for summer of 2006 at the Barrow Naval Arctic Research Laboratory (NARL). (1) Samples will be collected as for the long-term monitoring program at the Airstrip, Powerhouse, and Bulk Fuel Tank Farm sites. As needed, any unusable monitoring wells will be replaced. Samples will include active zone groundwater samples at all three sites, surface water samples from Imikpuk Lake adjacent to the Powerhouse and Airstrip Sites, and surface water and sediment samples in the North Salt Lagoon adjacent to the Bulk Fuel Tank Farm site. (2) Samples will be collected to fill data gaps in site characterization at the Antenna Field Site (which encompasses the area known as the Old Waste Disposal Site) for DRO, GRO, RRO, VOCs, and SVOCs along the shoreline of the Middle Salt Lagoon; for petroleum and to evaluate for possible presence of a buried transformer at the abandoned communications station Quonset hut; for GRO, DRO, RRO in high anomaly areas indicating high concentrations of buried waste; and a surface debris survey will be conducted to identify and map surface debris that may post a physical hazard to people using the site. (3) Confirmation samples will be collected from land-farmed soil at the Bulk Fuel Tank Farm to fill data gaps that resulted from insufficient confirmation sampling at the conclusion of soil treatment operations.

3/2/2007	Document, Report, or Work plan Review - other	Reviewed and sent approval letter for draft 2006 Annual Monitoring Report for the NARL Airstrip, Powerhouse, and Bulk Fuel Tank Farm Sites. This monitoring report describes visual site inspections, well installations and reinstallations, sampling activities, and presents the results of active zone ground water, surface water sampling conducted during July and September, 2005, for the Airstrip, Powerhouse, and Bulk Fuel Tank Farm Sites, and sediment sampling in the North Salt Lagoon adjacent to the Bulk Fuel Tank Farm Site during September, 2005. This is the fourth year of monitoring following soil cleanup activities at the Airstrip site and the third year for the Powerhouse and Bulk Fuel Tank Farm sites. This report shows that at this point in time, contaminant concentrations at most of the wells at each of the sites do not show clear trends. A few wells show decreasing or probably decreasing levels of one or more petroleum constituent. Data analysis shows an increasing trend in concentrations of diesel range organics in one well at the Airstrip site. No exceedance of drinking water standards was detected in Imikpuk Lake samples.

5/6/2008	CERCLA ROD Periodic Review	Reviewed and sent comments on First Five Year Review – Airstrip (Site 5), Powerhouse (Site 12), and Bulk Fuel Tank Farm (Site 13). This report reviews information on past cleanup actions and long-term monitoring at the Barrow Naval Arctic Research Laboratory (NARL) Airstrip, Powerhouse, and Bulk Fuel Tank Farm sites, evaluates the effectiveness of the past cleanup actions, and makes recommendations for the future. The report concludes that overall the actions implemented at these three sites remain protective of human health and the environment. The report recommends continuing a monitoring program similar to the past five years, but makes a few specific recommendations for modifications to the monitoring program. The report recommends an engineering inspection of the cap at the Airstrip south depression. The report makes several recommendations for the Bulk Fuel Tank Farm site, including adding lead as a contaminant of concern, assessing the feasibility of removing additional soil from the south bank area and the historical sampling location “90,” and collecting additional samples to evaluate the land farm soil. The report also recommends meeting with the Ukpeagvik Iñupiat Corporation (UIC) and the Bureau of Land Management (BLM) to resolve concerns regarding the Powerhouse site.

5/15/2008	Document, Report, or Work plan Review - other	Approval letter sent for final 2007 Annual Monitoring Report, NARL Airstrip, Powerhouse, and Former Bulk Fuel Tank Farm. This report presents sampling results for 2007 monitoring of active zone water, surface water, and sediment at the Barrow Naval Arctic Research Laboratory (NARL) Airstrip, Powerhouse, and Bulk Fuel Tank Farms sites, conducted in July and September of 2007. Field activities were cut short during the September sampling event when the field personnel conducting sampling at the Bulk Fuel Tank Farm were accosted by an individual with a gun and instructed to leave. ADEC was informed of the situation when it occurred, and concurred with the Navy decision to withdraw the sampling crew from the field. As a result of the incident, some of the monitoring samples scheduled for September were not collected, and the confirmation samples at the Bulk Fuel Tank Farm former landfarm location also were not collected. However, since these sites will have ongoing monitoring, future data will be available for evaluating trends and assuring protection of human health and the environment. ADEC sent review comments on the draft report on March 4, 2008. Letters for draft and final reports were sent to Grady May, USN remedial project manager.	Tamar Stephens

4/15/2009	Document, Report, or Work plan Review - other	Reviewed and sent comments on a short report titled “Optimization Review – Sites 5, 12, and 13 at Naval Arctic Research Laboratory, Barrow Alaska” (February 2, 2009). DEC received this report on March 17, 2009. This report evaluates the long-term monitoring programs for three sites at the Barrow Naval Arctic Research Laboratory (NARL): Powerhouse Site, Airstrip Site, and the Bulk Fuel Tank Farm Site. It identifies three broad issues related to frequency of sampling, monitoring wells and monitoring parameters, and natural attenuation and makes several recommendations for reducing or eliminating specific elements of the monitoring program and using the cost savings to do additional investigation to support better management of contaminant plumes or to do residual source removal. (1) The report recommends reducing the sampling frequency to one time each year instead of two times and states that a single August or September sampling event would provide a fair representation of the groundwater. DEC concurred that at present one annual sampling event would provide adequate monitoring information on these sites. Once the monitoring results indicate that a site is at or near the target cleanup levels, the sampling frequency may need to be restored to twice a year to confirm that seasonal variations in contaminant concentrations do not exceed cleanup levels. (2) The report recommends eliminating specific sampling locations from the active zone groundwater monitoring program. At the Airstrip site, WP-21 has been monitored to provide background parameters; the report concludes that it may have served its purpose in providing a benchmark for evaluating trends at the site. At the Bulk Fuel Tank Farm, the report concludes that four monitoring wells could be dropped from the program: WP-07 is too far cross-gradient from signs of currently elevated contaminants of concern; and WP-04, WP-05 and WP-06 are sited to detect plume movement toward the melt water pond, but the groundwater gradient shows that groundwater moves the opposite direction. DEC concurred. (3) The report recommends consideration of doing additional source investigation for residual sources of petroleum contamination containing free-phase petroleum, using a drill rig equipped with a membrane interface probe. DEC concurred. (4) The Optimization Review Report recommends a more focused investigation into monitored natural attenuation to provide information that might support more active plume control or source management activities. DEC concurred. Letter was sent to Grady May, USN remedial project manager.	Tamar Stephens

12/2/2019	Document, Report, or Work plan Review - other	DEC reviewed the 2018 Continuation of Bioremediation Pilot Study of Soils at the Former Naval Arctic Research Laboratory Airstrip and Powerhouse Sites in Utqiagvik, Alaska, dated April 30, 2019.This pilot study was designed to evaluate if petroleum contamination in the soil at the Barrow NARL Airstrip and Powerhouse spill sites could be remediated in situ through use of nutrient additions and plantings in tilled soil.For this study, treatment plots were constructed in 2016, in two zones at the Power House and three zones at the Airstrip sites. Three study blocks were installed at each zone, and four plots within each block were established (one for each treatment). Treatments included tilling with no additions (control), nutrient additions (N), plantings (P), and nutrient additions and plantings (N+P). The plots were evaluated initially in 2016 and later in 2018, after three growing seasons.Results from the study indicated that, qualitatively, the treatments were marginally effective in remediating petroleum contamination after three growing seasons. In the case of some contaminants at some zones (i.e., toluene, ethylbenzene, xylenes, gasoline range organics, and diesel range organics at Airstrip Zone 2), the control treatment showed equal results to the nutrient additions and plantings, indicative of the relatively inconsistent effectiveness of bioremediation at the site. It is the view of DEC that due to the heterogeneous nature of the study results, a full scale-up of this bioremediation treatment at the Barrow NARL may not be the most effective remedy to clean up the contamination at the site. DEC recommends that the avenues of remediation under the ROD for the sites be pursued to achieve site cleanup.	Kevin Fraley
8/19/2021	Document, Report, or Work plan Review - other	Completed review of the 2020 Annual Monitoring Report, Long-Term Monitoring, Operations, and Maintenance at the Airstrip, Powerhouse, and Former Bulk Fuel Tank Farm. This report detailed the long-term monitoring activities conducted during the 2020 field season. This work was conducted to assess whether geochemical indicators in the active zone water are indicative of hydrocarbon biodegradation, to evaluate contaminant levels in sediments at the BFTF site, and to evaluate progress toward achieving active zone water cleanup levels (CULs) through trend analysis and comparison with CULs. Geochemical parameters indicate that natural attenuation is occurring at varying degrees across the sites but no established degradation rates have been determined at this time. Contaminant concentrations in Imikpuk Lake surface water samples obtained from the Powerhouse and Airstrip sites reaming below CULs. One shoreline monitoring well at the Powerhouse site shows an increasing trend for DRO. Results for active zone water at the Airstrip site exceeded DRO CULs at three shoreline wells. Currently, it is unclear when the active zone water at the Airstrip site will achieve CULs via natural attenuation. At the Powerhouse site, with the exception of one well, monitoring wells had at least one contaminant above CUL. At the BFTF site, the number of monitoring wells with CUL exceedances were four. Both DRO and lead were detected in the North Salt Lagoon sediments.	Kelly Walker

Kelly Walker
9/21/2021	Meeting or Teleconference Held	Meeting held with Barrow NARL stakeholders to discuss the continuation of PFAS investigations at the Airstrip and UIC-NARL sites (Powerhouse location). NAVFAC, UIC, NSB, CH2M and ADEC were present. Work is planned for 2022. At the Powerhouse/UIC-NARL site, a PFAS Site Inspection will be conducted to determine presence/absence of PFAS at past storage and training locations identified by the previous sitewide PFAS PA. New active zone monitoring wells will be installed and sampled at the Powerhouse site. Existing wells will also be used for sample collection. Soil samples will also be collected. At the Airstrip site, a PFAS Remedial Investigation will be conducted to determine levels of PFAS substances in soils and active zone water. Active zone water flow direction and gradient will be analyzed. Surface water and sediment samples will be collected at Imikpuk Lake locations and at North Salt Lagoon locations.	Kelly Walker

This work plan describes the following sampling activities planned for summer of 2006 at the Barrow Naval Arctic Research Laboratory (NARL). (1) Samples will be collected as for the long-term monitoring program at the Airstrip, Powerhouse, and Bulk Fuel Tank Farm sites. As needed, any unusable monitoring wells will be replaced. Samples will include active zone groundwater samples at all three sites, surface water samples from Imikpuk Lake adjacent to the Powerhouse and Airstrip Sites, and surface water and sediment samples in the North Salt Lagoon adjacent to the Bulk Fuel Tank Farm site. (2) Samples will be collected to fill data gaps in site characterization at the Antenna Field Site (which encompasses the area known as the Old Waste Disposal Site) for DRO, GRO, RRO, VOCs, and SVOCs along the shoreline of the Middle Salt Lagoon; for petroleum and to evaluate for possible presence of a buried transformer at the abandoned communications station Quonset hut; for GRO, DRO, RRO in high anomaly areas indicating high concentrations of buried waste; and a surface debris survey will be conducted to identify and map surface debris that may post a physical hazard to people using the site. (3) Confirmation samples will be collected from land-farmed soil at the Bulk Fuel Tank Farm to fill data gaps that resulted from insufficient confirmation sampling at the conclusion of soil treatment operations.

This is the fourth year of monitoring following soil cleanup activities at the Airstrip site and the third year for the Powerhouse and Bulk Fuel Tank Farm sites. This report shows that at this point in time, contaminant concentrations at most of the wells at each of the sites do not show clear trends. A few wells show decreasing or probably decreasing levels of one or more petroleum constituent. Data analysis shows an increasing trend in concentrations of diesel range organics in one well at the Airstrip site. No exceedance of drinking water standards was detected in Imikpuk Lake samples.

This report reviews information on past cleanup actions and long-term monitoring at the Barrow Naval Arctic Research Laboratory (NARL) Airstrip, Powerhouse, and Bulk Fuel Tank Farm sites, evaluates the effectiveness of the past cleanup actions, and makes recommendations for the future. The report concludes that overall the actions implemented at these three sites remain protective of human health and the environment. The report recommends continuing a monitoring program similar to the past five years, but makes a few specific recommendations for modifications to the monitoring program. The report recommends an engineering inspection of the cap at the Airstrip south depression. The report makes several recommendations for the Bulk Fuel Tank Farm site, including adding lead as a contaminant of concern, assessing the feasibility of removing additional soil from the south bank area and the historical sampling location “90,” and collecting additional samples to evaluate the land farm soil. The report also recommends meeting with the Ukpeagvik Iñupiat Corporation (UIC) and the Bureau of Land Management (BLM) to resolve concerns regarding the Powerhouse site.

This report presents sampling results for 2007 monitoring of active zone water, surface water, and sediment at the Barrow Naval Arctic Research Laboratory (NARL) Airstrip, Powerhouse, and Bulk Fuel Tank Farms sites, conducted in July and September of 2007. Field activities were cut short during the September sampling event when the field personnel conducting sampling at the Bulk Fuel Tank Farm were accosted by an individual with a gun and instructed to leave. ADEC was informed of the situation when it occurred, and concurred with the Navy decision to withdraw the sampling crew from the field. As a result of the incident, some of the monitoring samples scheduled for September were not collected, and the confirmation samples at the Bulk Fuel Tank Farm former landfarm location also were not collected. However, since these sites will have ongoing monitoring, future data will be available for evaluating trends and assuring protection of human health and the environment. ADEC sent review comments on the draft report on March 4, 2008. Letters for draft and final reports were sent to Grady May, USN remedial project manager.

Reviewed and sent comments on a short report titled “Optimization Review – Sites 5, 12, and 13 at Naval Arctic Research Laboratory, Barrow Alaska” (February 2, 2009). DEC received this report on March 17, 2009. This report evaluates the long-term monitoring programs for three sites at the Barrow Naval Arctic Research Laboratory (NARL): Powerhouse Site, Airstrip Site, and the Bulk Fuel Tank Farm Site. It identifies three broad issues related to frequency of sampling, monitoring wells and monitoring parameters, and natural attenuation and makes several recommendations for reducing or eliminating specific elements of the monitoring program and using the cost savings to do additional investigation to support better management of contaminant plumes or to do residual source removal. (1) The report recommends reducing the sampling frequency to one time each year instead of two times and states that a single August or September sampling event would provide a fair representation of the groundwater. DEC concurred that at present one annual sampling event would provide adequate monitoring information on these sites. Once the monitoring results indicate that a site is at or near the target cleanup levels, the sampling frequency may need to be restored to twice a year to confirm that seasonal variations in contaminant concentrations do not exceed cleanup levels. (2) The report recommends eliminating specific sampling locations from the active zone groundwater monitoring program. At the Airstrip site, WP-21 has been monitored to provide background parameters; the report concludes that it may have served its purpose in providing a benchmark for evaluating trends at the site. At the Bulk Fuel Tank Farm, the report concludes that four monitoring wells could be dropped from the program: WP-07 is too far cross-gradient from signs of currently elevated contaminants of concern; and WP-04, WP-05 and WP-06 are sited to detect plume movement toward the melt water pond, but the groundwater gradient shows that groundwater moves the opposite direction. DEC concurred. (3) The report recommends consideration of doing additional source investigation for residual sources of petroleum contamination containing free-phase petroleum, using a drill rig equipped with a membrane interface probe. DEC concurred. (4) The Optimization Review Report recommends a more focused investigation into monitored natural attenuation to provide information that might support more active plume control or source management activities. DEC concurred. Letter was sent to Grady May, USN remedial project manager.

DEC reviewed the 2018 Continuation of Bioremediation Pilot Study of Soils at the Former Naval Arctic Research Laboratory Airstrip and Powerhouse Sites in Utqiagvik, Alaska, dated April 30, 2019.This pilot study was designed to evaluate if petroleum contamination in the soil at the Barrow NARL Airstrip and Powerhouse spill sites could be remediated in situ through use of nutrient additions and plantings in tilled soil.For this study, treatment plots were constructed in 2016, in two zones at the Power House and three zones at the Airstrip sites. Three study blocks were installed at each zone, and four plots within each block were established (one for each treatment). Treatments included tilling with no additions (control), nutrient additions (N), plantings (P), and nutrient additions and plantings (N+P). The plots were evaluated initially in 2016 and later in 2018, after three growing seasons.Results from the study indicated that, qualitatively, the treatments were marginally effective in remediating petroleum contamination after three growing seasons. In the case of some contaminants at some zones (i.e., toluene, ethylbenzene, xylenes, gasoline range organics, and diesel range organics at Airstrip Zone 2), the control treatment showed equal results to the nutrient additions and plantings, indicative of the relatively inconsistent effectiveness of bioremediation at the site. It is the view of DEC that due to the heterogeneous nature of the study results, a full scale-up of this bioremediation treatment at the Barrow NARL may not be the most effective remedy to clean up the contamination at the site. DEC recommends that the avenues of remediation under the ROD for the sites be pursued to achieve site cleanup.

Document, Report, or Work plan Review - other

Completed review of the 2020 Annual Monitoring Report, Long-Term Monitoring, Operations, and Maintenance at the Airstrip, Powerhouse, and Former Bulk Fuel Tank Farm. This report detailed the long-term monitoring activities conducted during the 2020 field season. This work was conducted to assess whether geochemical indicators in the active zone water are indicative of hydrocarbon biodegradation, to evaluate contaminant levels in sediments at the BFTF site, and to evaluate progress toward achieving active zone water cleanup levels (CULs) through trend analysis and comparison with CULs. Geochemical parameters indicate that natural attenuation is occurring at varying degrees across the sites but no established degradation rates have been determined at this time. Contaminant concentrations in Imikpuk Lake surface water samples obtained from the Powerhouse and Airstrip sites reaming below CULs. One shoreline monitoring well at the Powerhouse site shows an increasing trend for DRO. Results for active zone water at the Airstrip site exceeded DRO CULs at three shoreline wells. Currently, it is unclear when the active zone water at the Airstrip site will achieve CULs via natural attenuation. At the Powerhouse site, with the exception of one well, monitoring wells had at least one contaminant above CUL. At the BFTF site, the number of monitoring wells with CUL exceedances were four. Both DRO and lead were detected in the North Salt Lagoon sediments.

Document, Report, or Work plan Review - other

Review completed for the 2021 Tier II Sampling and Analysis Plan Addendum, Long-Term Monitoring, Operations, and Maintenance at the Airstrip, Powerhouse, and Former BFTF sites. This work plan is for the active zone water, surface water, and soil sampling to be conducted during the 2021 field season. Active zone water and surface water samples will be collected at the Airstrip and Powerhouse sites to evaluate current contaminant levels and to determine the status of natural attenuation of contaminants through collection of geochemical indicators. Active zone water and sediment will be collected at the BFTF to evaluate contaminant levels.

Review completed for the Tier I Sampling and Analysis Plan 2021 Diesel Range Organics Fractionation and Per- and Polyfluoroalkyl Substances Sampling for the Airstrip and Powerhouse sites. The objectives of this sampling effort are to: -Determine if PFAS are present in the soil at or near Imikpuk Lake at the Airstrip and Powerhouse sites, and if present, use this information to inform costing estimates for offsite disposal requirements for the future petroleum removal action -Determine if PFAS are present in the active zone water near Imikpuk Lake at the Powerhouse sites, and if present, evaluate whether there is a potentially unacceptable risk to human health -Determine if DRO aliphatic concentrations in the inland wells at the Airstrip and Powerhouse sites exceed the Airstrip and Powerhouse cleanup level This work plan was approved on 8/19/2021.

Meeting or Teleconference Held

Meeting held with Barrow NARL stakeholders to discuss the continuation of PFAS investigations at the Airstrip and UIC-NARL sites (Powerhouse location). NAVFAC, UIC, NSB, CH2M and ADEC were present. Work is planned for 2022. At the Powerhouse/UIC-NARL site, a PFAS Site Inspection will be conducted to determine presence/absence of PFAS at past storage and training locations identified by the previous sitewide PFAS PA. New active zone monitoring wells will be installed and sampled at the Powerhouse site. Existing wells will also be used for sample collection. Soil samples will also be collected. At the Airstrip site, a PFAS Remedial Investigation will be conducted to determine levels of PFAS substances in soils and active zone water. Active zone water flow direction and gradient will be analyzed. Surface water and sediment samples will be collected at Imikpuk Lake locations and at North Salt Lagoon locations.
