Contaminant groups quantified were: pesticides, personal care products, pharmaceuticals and hydrocarbons. Trace metals analysis of benthic sediments was also conducted. Additionally, standard suite of nutrient parameters (nitrate, nitrite, ammonium, urea, total nitrogen, orthophosphate, total phosphorus and silica), as well as tracers of human waste (sucralose and caffeine) were quantified at eight targeted sites (bottom samples) during the same time period. American Samoa’s reefs are considered to be among the most pristine in the United States. These reefs host approximately 950 species of fish, 240 species of algae, 330 species of coral and many other species of invertebrates. Fagatele Bay, a unit of the National Marine Sanctuary of American Samoa (NMSAS), is located on the south shore of the island of Tutuila, the largest and most populous island of the U.S. territory of American Samoa. There have been local concerns about the impacts of land-based sources of pollution and water quality on the coral reef ecosystems of the Bay, specifically related to an unlined solid waste landfill upslope from the Bay. Organic and inorganic chemical contaminants have a wide range of potential negative impacts on the marine environment, including endocrine disruption, loss of habitat and changes in species composition. Environmental data, such as the dataset presented here, serve as a baseline of current conditions, which are needed determine the efficacy of management efforts, i.e., measuring change over time. The data presented here can be utilized by coastal managers to best prioritize management strategies in a way to maximize success in decreasing stressors on coral reef ecosystems. Partners included: National Marine Sanctuary of American Samoa, American Samoa’s Coral Reef Advisory Group, ASEPA, and American Samoa Community College.

(1967). Ammonium analysis was based on the method of Harwood and Kuhn (1970) using dichloro-isocyanurate as the oxidizer. Urea was measured using diacetyl-monoximine and themicarbozide with colorimetric analysis. The total concentration of nitrogen was determined after an initial decomposition step. This method involves persulfate oxidation while heating the sample in an autoclave (115°C, 20 minutes) (Hansen and Koroleff, 1999). After oxidation of the samples, nitrogen determination was conducted on the Astoria Pacific analyzer for nitrate. The total concentration of phosphorus was determined after an initial decomposition step. This method involves persulfate oxidation while heating the sample in an autoclave (115°C, 20 minutes) (Hansen and Koroleff 1999). After oxidation of the samples, phosphorus determination was conducted on the Astoria Pacific analyzer for orthophosphate. Silicate determination was accomplished using the methods of Armstrong et al. (1967) using stannous chloride.; Data Quality Method: All laboratory data contained blanks, spikes and percent recoveries. Data were QA/QC’d using National Status and Trends protocols.
