The National Oceanic and Atmospheric Administration (NOAA) has performed site characterization and restoration on St. Paul Island, Pribilof Islands, Alaska and monitored groundwater for diesel range organics, gasoline range organics, volatile organic compounds, semi-volatile organic compounds, metals, and total dissolved solids at monitoring wells located at multiple sites. Starting in June 2006, NOAA began long-term groundwater monitoring on a semi-annual basis and contracted Bethel to continue groundwater monitoring beginning in 2008. Contaminants of concern and representative wells were chosen for long-term monitoring at five sites, which include the City of St. Paul, Icehouse Lake, the Diesel Seep near Salt Lagoon, the St. Paul Municipal Landfill, and the National Weather Service Station Landspreading Area/Oil Drum Dump Site. Mann-Kendall statistical methods were used to evaluate contaminant trends at 21 of the 30 wells for a total of 45 calculated trends. Based on our exemplary past performance, Bethel was awarded a sole-source contract for additional groundwater monitoring in 2011-2012.
