Table 1.
Calculated Action Levels (mg/kg or ppm) based on estimated seafood consumption rates. Potential exceedances based on maximum contaminant concentrations detected are highlighted.

∗Values in bold show all Action Level exceedances for gastropods collected at Lauli'i Beach. Gastropods collected from inner Nu'uuli exceeded for summed PCBs, Chlordane/Nonachlor, and Mirex, and from Pago Harbor exceeded for Chlordane/Nonachlor and DEHP. Rock oysters at Lions Park exceeded for Chlordane/Nonachlor and summed PCBs.
