       "description": "The Sediment-Contaminant Database for the Upper Mississippi River System contains information from a total of 3950 analyzed sediment samples, including 2697 from the Mississippi River, 440 from the Illinois River, and 813 from tributaries. These samples were collected during 1974 through 2000, with 262 samples from the 1970s, 2168 from the 1980s, 1518 from the 1990s, and 2 from the year 2000. The database contains data on metals, metalloids, nutrients, polynuclear aromatic hydrocarbons, insecticides, herbicides, fungicides, industrial compounds, sterols, petroleum-related compounds, and polychlorinated biphenyls in three types of samples: bed sediment (86.6% of the samples), sediment trap (1.8%), and pore water (11.6%). The relative completeness of quality-assurance documentation for each of 44 discreet data sets entered was characterized by a quality-assurance index. To facilitate interpretation, the database provides information on sampling locations. Methods of sample collection, physical characteristics of analyzed sediment, and other ancillary variables for each sample. The database is available on CD-ROM or through the Internet. The overall goal was to create a comprehensive database with data of known quality that would be readily available to interested users, to facilitate the assessment of riverine contamination, to increase the availability of historic sediment-contaminant data, and to facilitate management and scientific efforts pertaining to contaminated-sediment issues in the river system.",
