| Figure 4 gives the locations of sediment samples from the sources in the database (appendixes C and D). A few additional sources were identified in library searches but have not been entered into the database because of limited contributions to existing information or special problems like insufficient location data. | (click on image for a larger view) |

| A numerical index grid (fig. 6) is included in the database (appendixes C and D) for analysis purposes. This index provides a convenient way to search on data from specific localities covered by the database. Sorting of the sediment data in spreadsheet form by grid number and specific chemical parameters has been used to compare group data from independent sources for specific local areas as a part of data quality screening. Indexing may be helpful when the presently available sediment data are combined with other information, such as biological data or toxicity measurements. | (click on image for a larger view and opportunity to
