CERCLA RI Report Approved |
The ADEC Contaminated Sites Program approved the Final Remedial Investigation Report. The report concluded that 90 MEC items were found at the Possible Munitions Storage Area East, the calculated density for the 5.35 acre site was 90.7 UXO/acre. MEC is present in the top of the mineral soil. Concentrations of antimony, lead, manganese, 2,4-DNT, and 2,6-DNT exceeded human health screening criteria. Concentrations of antimony, manganese, total chromium, lead, zinc, copper, and 2,4-DNT exceeded ecological screening criteria. A feasiblity study was recommended to determine appropriate remedial responses, based on the current and future land use. |

Site Visit |
ADEC staff travelled to Eareckson Air Station for 3 days to conduct site visits and institutional control inspections. Site visits were conducted to all pertinent sites and meetings were held to with ADEC and USAF to discuss a path forward for the sites. The interim institutional controls for the MMRP sites need to be updated: the safety briefing upon arrival at Shemya does not include UXO awareness, the MMRP sites are not all shown on informational maps, and signs are missing from several sites. |
