Sample collection will be performed primarily by the NERT with some assistance from the principal USGS investigator. The data from this component of the study will be used to determine what organic contaminants are present in the Neuse River watershed and their temporal and spatial distribution in the sediment and water. The USGS will provide expertise in the experimental design of SPE and ASE methods for the analysis of target compounds in water, sediment, and tissue. Presented papers on the occurrence and analysis of antibiotics at North Carolina State University, the USGS National District Chiefs and National Water Quality Specialists Meetings, and at the Society of Environmental Toxicology and Chemistry. The work on antibiotics has led to Interagency Agreements with the Centers for Disease Control, two other EPA branches, and projects with the Iowa District Office and the Toxics Substances Hydrology Program.
More potential projects are pending.
