| 8/20/2015 | Site Characterization Workplan Approved | The ADEC Contaminated Sites Program received the Final Dutch Harbor Limited Removal Action Work Plan, Amaknak and Unalaska Islands, Alaska. The work plan was not formally approved, but ADEC does not object to the site characterization portions of the work plan. A report should be submitted documenting these site characterization activities.

Contaminant Information
| Name | Level Description | Media | Comments |
|---|---|---|---|
| DRO | Between Method 2 Migration to Groundwater and Human Health/Ingestion/Inhalation | Soil | The DRO detection of 1,140 mg/kg fell below the ADEC Method 3 alternative cleanup level of 8,300 mg/kg, calculated using site specific TOC data collected in 2008. |
| Arsenic - Total | Other | Soil | Arsenic was detected in both samples, exceeding ADEC Method 2 cleanup criterion of 0.2 mg/kg. One sample was below the background cleanup concentration calculated for Amaknak and Unalaska Islands (10 mg/kg). Another sample, although slightly exceeding the calculated background cleanup level, was still considered within the expected range for natural soils in the area. |
