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.
The Sediment-Contaminant Database for the Upper Mississippi River System (version 2) contains reliable sediment-contaminant data of known quality in a readily accessible format. The database was compiled to facilitate the assessment of riverine contamination, to increase the availability of historic sediment-contaminant data, to facilitate responses to contaminant issues in the Upper Mississippi River System, and to focus management and scientific efforts pertaining to contaminated-sediment.
Forty four (44) data sets on sediment-associated contaminants in the Upper Mississippi River, the Illinois River, and selected tributaries have been entered into version 2 of the database, which contains information from a total of 3950 analyzed sediment samples collected from 1974 through 2000. This total includes 2697 samples from the Upper Mississippi River, 440 from the Illinois River, and 813 from selected tributary streams. Groups of contaminants represented in the database include metals, metalloids, nutrients, polynuclear aromatic hydrocarbons, insecticides, herbicides, fungicides, industrial compounds, sterols, petroleum-related compounds, and polychlorinated biphenyls.

Considerable care was taken to ensure the reliability of contaminant data entered into the database. The relative completeness of quality-assurance documentation for each discreet data set entered was characterized by a quality-assurance index. To facilitate the interpretation of the contaminant data, the database provides information on sampling locations, methods of sediment collection, physical characteristics of the analyzed sediments, and other ancillary variables for each sediment sample represented.
Data set is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.
No formal positional accuracy tests were conducted
