11/19/1999 |
Update or Other Action |
ADEC (Shah Alam) has written to the Olgoonik Corporation (Lucille Mayer) not approving transfer of contaminated soils excavated from the Water Treatment Plant to the biocell at this time and also has asked not to add any more contaminated soils to the biocell until further approval from ADEC. Based on the information submitted to date for the Wainwright bioremediation cell, the Department is unable to evaluate the effectiveness of treatment. The treatment cell was approved conditional on annual sampling events. The cell was only sampled once on October 9, 1997 with no sample data from subsequent years and this is not considered adequate for purposes of establishing a trend in contaminant levels. Unfortunately, the sample procedures did not conform to the Department’s QA/QC standards for sample collection, transport and analysis and the results are therefore questionable. |

Document, Report, or Work plan Review - other |
Date of receipt of document entitled Wainwright Washeteria, Draft Site Characterization Work Plan. Work is scheduled to begin end of April. This effort will include 5 borings to be completed as monitoring wells with two soil samples will be collected from each boring. The soil samples will be analyzed for GRO/DRO/RRO and VOCs as well as 10 percent PAHs. Wells will be sampled later in the season around September with the analytical suite to GRO/DRO/RRO/VOCs/PAHs. Up to five collocated surface water and sediment samples will also be collected in September. Sediment samples will be analyzed for the same analytical suite as the soil samples and the surface water samples will be analyzed for VOCs and PAHs. |

Document, Report, or Work plan Review - other |
Reviewed the Site Characterization Report, dated March 24, 2016. Five soil borings were advanced at the site, all of which were completed as monitoring wells. Samples were collected from the soil borings and monitoring wells as appropriate, and also from four co-located sediment and surface water sample locations. Five analytical soil samples were collected from the surface pad material (0 to 2 feet bgs); four samples were collected from the subsurface porous pad material; one soil sample was collected from the subsurface non-porous native material (SB-03); five water samples were collected from the monitoring wells; and four co-located soil sediment and surface water samples were also collected. All soil and water samples were submitted for one or more of the following: diesel range organics (DRO), gasoline range organics (GRO), residual range organics (RRO), volatile organic compounds (VOCs), and/or polynuclear aromatic hydrocarbons (PAHs).
Analytical results revealed that contamination is present above the applicable cleanup criteria in the non-porous native material, sediment soil, and suprapermafrost groundwater. Levels of DRO, naphthalene, xylenes, and 1,2,4-trimethylbenzene were identified in the non-porous native material (Sample SB-03) at 17,200 mg/kg, 80.5 mg/kg, 94.7 mg/kg, and 83.3 mg/kg, respectively, all of which exceed the Method Two soil cleanup levels. Benzene and DRO were present in the suprapermafrost groundwater up to 0.066 mg/l and 1.82 mg/l, both of which exceed the Table C groundwater cleanup levels. None of the surface water samples exceeded the Alaska Water Quality Standards (AWQS) for total aromatic hydrocarbons (TAH) or total aqueous hydrocarbons (TAqH). Two of the four co-located sediment samples exceeded NOAA Screening Quick Reference tables (SQuiRTs) for several PAHs.
Results generally indicated that the pad material and suprapermafrost groundwater are impacted, and that contamination is migrating into the sediment soils. It does not appear that the extent of suprapermafrost groundwater has been delineated.
Recommendations in the report include: re-routing the ponded surface water to a culvert and then filling in those areas with gravel to grade to mitigate the sediment and potential surface water exposure pathways; installation of a reactive barrier between MW-04 and MW-03 to remove contamination from groundwater; and groundwater monitoring of MW-05 in 2017.
In a letter dated April 13, 2016 ADEC requested a work plan for further delineation and mitigation of surface water/sediment exposure pathways. |

Document, Report, or Work plan Review - other |
Reviewed NSB Wainwright Washeteria Site Characterization Report, dated November 2017. This report details the activities completed during the 2016 field effort at the NSB Wainwright Washeteria site. Completed activities generally included advancing seven soil borings, all of which were completed as monitoring wells; backfilling two low-lying depressions with gravel to eliminate the surface water exposure pathway; and surveying four wells to determine porewater flow direction and gradient. Two soil samples were collected from each soil boring. Water samples were collected from the 7 new wells and the 5 existing wells. Porewater flow direction was determined to be northwest at a gradient of 0.019 feet per foot. All soil and water samples were submitted for analysis of diesel range organics (DRO), gasoline range organics (GRO), residual range organics (RRO), and volatile organic compounds (VOCS). All water samples and two soil samples were also analyzed for polycyclic aromatic hydrocarbons (PAHs).
Results of the investigation are consistent with historical data, as contamination appears to be sporadic and from multiple source areas. Except for the samples collected from Borings SB-09 and SB-12, all soil results were below human health and maximum allowable concentrations (MACs) as defined in ADEC Method Two Tables B1 and B2. The soil sample collected from SB-12 at 3 feet below ground surface (bgs) exhibited a concentration of DRO at 15,600 mg/kg, which exceeds the MAC for DRO. The sample collected from SB-09 at 5.5 feet bgs had several VOC and PAH fractions above human health levels. It should be noted that Boring SB-12 was collected in the vicinity of a former bulk fuel tank storage area, which may be the source of DRO. Boring SB-09 is located in the vicinity of a 1997 spill, although could be a more recent release as well.
Ten (10) of the 12 porewater monitoring wells had at least one constituent exceeding the ADEC Table C groundwater cleanup levels. Well MW-01 is located across Main Street and appears to have a higher level of benzene than other wells located closer to the site, which may indicate yet another source area. However, it should also be noted that there used to be (and maybe still) a culvert that ran through Main street in the vicinity of MW-01.
Report recommendations include continued porewater monitoring and disposal of soil cuttings from the 2016 activities. ADEC concurred with these recommendations but also requested removal of soil exceeding Method Two MACs or human health cleanup levels. |

Document, Report, or Work plan Review - other |
Comments on a workplan, submitted on September 13, 2020, were provided to the NSB Department of CIPM. The workplan described assessment activities in support of a construction and demolition project scheduled for 2021. The construction and demolition project will expand to the southeast of the water treatment plan and demolish to the northwest of the water treatment plan. The expansion area footprint includes the location of a former fuel storage area where previous investigation indicates that contaminated soil is still present. One location of the expansion area had DRO exceeding maximum allowable contamination at 3 feet deep.
Comments requested more detail of the 2021 project and a separate contaminated soil management plan prior to the proposed project.

Site Characterization Workplan Approved |
Soil management plan in support of construction approved. Upper two feet on the east side has been characterized and can be used as clean backfill if screened below 10 ppm. Two areas on the east side with contamination will be marked off and potentially dirty and stockpiled and sampled separately. All material below two feet will be segregated according to PID reading, stockpiled, and sampled. All material on the west side will be segregated according to PID reading, stockpiled, and sampled. Clean material will be reused. Dirty material will be shipped to Oxbow landfill in 2021 or 2022. Stockpiles will be stored at the "old airport site" owned by NSB.
During approval, strongly recommended vertical characterization in areas where permanent infrastructure will be placed. |
