Problems/Comments
A historic cache of 55-gallon drums dating from 1940's and 1950's were discovered in a 2011 survey of the Sage Hill area. They may have previously been used to store a variety of materials (oil, pesticides, tetrachloroethylene, etc.). Fifty-two drums were removed, and it is unclear whether any drums remain at the site. No odor or staining was observed around or under any drums. Based on field screening results, only surface soil samples (not subsurface soil samples) were collected. Soil and surface water samples were analyzed for gasoline range organics, diesel range organics (DRO), residual range organics (RRO), volatile organic compounds, semi-volatile organic compounds, polychlorinated biphenyls, herbicides, and pesticides. Soil samples were analyzed for RCRA metals. Concentrations for DRO (2,500 mg/kg) and RRO (2,100 mg/kg) in soil samples exceeded migration-to-groundwater cleanup levels. Multiple metals were detected at 1/10th their respective human health risk soil cleanup levels. The analysis of the surface water samples was inconclusive. Further investigation of surface water is needed. Potential receptors include site visitors and workers.

| 8/26/2020 | Document, Report, or Work plan Review - other | The Alaska Department of Environmental Conservation (DEC) has completed a review of the "Draft Uniform Federal Policy–Quality Assurance Project Plan FTW418 Repair Sage Hill Road Fort Wainwright, Alaska (Revised August 4, 2020, version 4)" provided by Fort Wainwright, Alaska (FWA) on August 6, 2020. The purpose of this Uniform Federal Policy-Quality Assurance Project Plan (UFP-QAPP) is to detail the field screening and subsequent analytical requirements before, during, and after construction activities on Sage Hill located on FWA. The planned project includes improvements to Sage Hill Road and construction of a new Ammunition Supply Point. Work includes improvements to the gravel access roads to the Ammunition Supply Point and construction of a new Ammunition Handling Area on FWA. | Sara Marshall |
| 9/10/2020 | Document, Report, or Work plan Review - other | ADEC approved the Uniform Federal Policy-Quality Assurance Project Plan (UFP-QAPP), FTW418 Repair Sage Hill Road, Fort Wainwright, Alaska (revised September 10, 2020, version 6). The document describes the field screening and subsequent analytical requirements for before, during and after construction activities to improve Sage Hill Road, and construct a new Ammunition Supply Point, with new gravel access roads on Fort Wainwright, Alaska (FWA). This work is expected to occur Fall 2020. | Erica Blake |
| 9/28/2020 | Document, Report, or Work plan Review - other | ADEC approved the Final Preliminary Source Evaluations Work Plan, Fort Wainwright, Alaska (dated September 2020). The document describes a proposed investigation approach for preliminary source evaluations (PSEs) at multiple sites located on Fort Wainwright, Alaska (FWA). The sites planned for investigation are; CANOL Pipeline Pump Station, North Refueling (four source areas), Building 3480 UST 208, Building 3030 South Loading Dock, TCE in monitoring well AP-5531 (near Building 3007 Drainage Swale), Building 3038 and Sage Hill. The objective of conducting this PSE work is to determine if contamination remains that may present a threat to human health or the environment, and to determine appropriate further action. This PSE work is expected to occur Fall 2020. | Erica Blake |
| 5/10/2021 | Document, Report, or Work plan Review - other | ADEC provided review comments for the "Draft Preliminary Source Evaluation Report, Sage Hill, Fort Wainwright, Alaska" (dated April 2021) to the U.S. Army. The document describes preliminary source evaluation (PSE) sampling activities conducted at Sage Hill on Fort Wainwright, Alaska. The purpose of the PSE was to determine if the contaminant concentrations on site could present a threat to human health and the environment, and to determine appropriate management options. | Erica Blake |
