Glossary of Table Abbreviations and Data Validation Qualifiers

U

The analyte was analyzed for and is not present above the level of the associated value.  The associated numerical value indicates the approximate concentration necessary to detect the analyte in the sample.

J

The analyte was analyzed for and was positively identified, but the associated numerical value may be imprecise due to a quality control (QC) anomaly.  The data are considered usable for many purposes.

ft bgl

Feet below ground level

DUP

Sample duplicate
