Remedial Investigation and Feasibility Study Support (RI/FS)

National Oceanic Atmospheric Administration (NOAA)

Pribilof Islands, Alaska

NOAA contracted CESI/dse to assess environmental impacts from prior activities to various sites on St. Paul Island. These sites had been impacted by various activities on the island since it came under the aegis of the United States of America. Many of these sites were impacted by diesel fuels, other petroleum hydrocarbons, and metals. The assessment activities were accomplished in support of planned remedial activities, which were intended to return the island to near pristine condition prior to returning the sites to the indigenous population. dse personnel installed and logged over 60 soil borings that were advanced and converted into monitoring wells. The monitoring wells were used to collect groundwater characterization data, and to determine the hydrogeologic properties of the aquifer on the island. The water samples and soil cuttings were analyzed to determine the extent of impacts to the groundwater or vadose zone. dse personnel removed three underground storage tanks, and participated in the geological mapping of parts of the island. Phase I building condition surveys were also conducted by a dse field crew for several buildings that were used and/or operated by NOAA or other Federal Government agencies.
