Document, Report, or Work plan Review - other |
Date of document entitled NSB Point Lay DMS Drum Storage Area Site Characterization report. Activities performed in 2014 include advancement of 18 borings, collection of soil samples from 13 of those borings, conversion of four boring into monitoring wells, collecting groundwater samples, and five surface water samples. Contaminants of concern found above cleanup levels in soil include GRO and DRO. GRO, DRO and benzene as well as TAH and TAqH exceedances were found in GW samples. Agviq is recommending a removal effort of soil acting as a source of groundwater contamination as GW daylights into surface water at this site. |

Document, Report, or Work plan Review - other |
Reviewed the Phase I-II Removal Action Report, dated July 20, 2017 and received on October 3, 2019. The report describes the 2015 and 2016 excavation efforts performed at this site. Confirmation samples collected from the excavations indicated that DRO (up to 2,770 mg/kg) and GRO (up to 275 mg/kg) remain in the pad and tundra material at concentrations above the Method One Table A2 cleanup levels, but below risk-based Method Two cleanup levels for the Arctic Zone. Recommendations provided in the 2017 report included additional removal actions and long-term porewater monitoring. Requested a work plan to delineate the site. |

Document, Report, or Work plan Review - other |
Reviewed and approved NSB Point Lay Water and Sewer Upgrade Limited Site Characterization Report dated April 2023.The site characterization report summarizes the results of 2022 site work done to assess an area of the site for construction of a proposed new vacuum-sewer building as part of upgrades to the Point Lay water and sewer system. NSB’s contractor installed two collocated environmental and geotechnical soil borings and collected soil for laboratory analysis. Analytical soil sample results indicated that GRO, DRO, nine volatile organic compounds (VOCs) including benzene, toluene, ethylbenzene, xylenes, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, isopropylbenzene, naphthalene, and n-propylbenzene , and three polycyclic aromatic hydrocarbons (PAHs), including 1-methylnaphthalene, 2-methylnaphthalene, and naphthalene were present in site soils above the most stringent DEC Method One or Method Two CULs. The lateral and vertical extent of impacted soil has not been determined at the site, and groundwater impacts not fully investigated. |

Update or Other Action |
In April 2022, NSB conducted a limited site characterization effort in support of a potential water source development project in Point Lay. One boring (G22-EB03) was advanced to 30 feet bgs on Lot 8, west of the NSB Point Lay DMS Drum Storage Area contaminated site (Hazard ID 25365) at the water treatment plant. Three laboratory analytical samples were collected between 5 and 20 feet bgs and analyzed for GRO, RRO, DRO, VOC, and PAH. Sample results included total xylenes, 1,2,4-trimethylbenzene, and naphthalene exceeding the Arctic Zone Human Health cleanup levels at 5-7.5 feet bgs.
