Sediment and water sampling results, Phase III: ALCOA-Davenport Facility:
Sampling Purpose: This study was conducted by the Woodward-Clyde consulting firm for the Aluminum Company of America (Alcoa) facility near Davenport, Iowa. Samples were collected for Phase III of an Administrative Order of Consent (AOC) with the United States Environmental Protection Agency (USEPA) covering sediment/soil investigation in onsite draingeways and wetlands, and within critical areas of Upper Mississippi River Pool 15. The Phase III sampling was conducted specifically to quantify the vertical and horizontal extent of contamination within the Pool 15 study areas. Sediment core and grab samples were collected and analyzed for organic carbon, particle size, metals, polynuclear aromatic hydrocarbons, polychlorinated biphenyls, and miscellaneous industrial compounds. Sample coordinate information was not provided with this study; however, coordinates were approximated in ArcView using detailed maps.
