Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 6/13/2003 | CERCLA SI | The 2001/2002 Islandwide SI/RI/IRA Report was received. The report documents the work completed during the 2001 and 2002 field seasons at various sites throughout Amaknak and Unalaska. Site reconnaissance in 2001 revealed 62 drums, 57 of which were empty and five of which contained material. Empty drums were transported to a local landfill for disposal. The remaining five drums were transported to the contaminated soil stockpile and placed in overpacks. Samples were collected from the site from areas beneath the drums and where there were signs of stressed vegetation or soil staining. Chromium, arsenic, and DRO were detected above cleanup levels. The site is recommended for no further action becuase an alternative cleanup level for DRo was calculated for the DRO exceedance and the metals exceedances are likley natually ocurring. | Meghan Dooley |
