Appendix C
Consolidated Data Table

This table consists of more frequently used station data, inorganic, organic, and texture data extracted from the full database and presented in one table. (The full database is available in Appendix D). Tables like this lend themselves to plotting and analysis. Many descriptive fields are omitted, but the quality control fields containing warning flags are retained. "W" refers to a warning that the data in question shows unresolved differences in quality-screening tests from patterns expected for well-qualified samples from its type and location. They should be rechecked before they are used for regional environmental categorization or toxicity evaluation. Please note that a "0" in a concentration field means that the constituent was below detection limit for the method utilized.

A small sample of the consolidated table can be viewed in Table 1. It is available here in three formats:
