    • NCCOS Assessment: Chemical contaminants data from the Faga’alu Bay and Watershed, American Samoa before and after best management practices from 2014-01-18 to 2022-04-06 (NCEI Accession 0302885)

    Metadata Updated: November 1, 2025

    This dataset represents a “before and after” sediment sampling effort from Faga’alu Bay and watershed, American Samoa, to evaluate the effectiveness of best management practices at a quarry site. A suite of organic and inorganic parameters was quantified at twelve randomly selected and one targeted marine sites and four targeted stream site in 2014, including: polycyclic aromatic hydrocarbons (PAHs), pesticides, polychlorinated biphenyls (PCBs), trace elements, carbon, Clostridium perfringens abundance, and sediment grain size. Five of these sites were re-sampled in 2022 and analyzed for trace elements.
