|Lake Pontchartrain Basin: Bottom Sediments and Related Environmental Resources|
The data tables in appendixes C and D contain information from many sources and alternative methodologies that are not always directly comparable. Also, unresolvable problems or uncertainties were found within some data sets. Results of quality screening are abbreviated in the "Q" fields (qualifier fields) next to each concentration field, and important notes about methods and sample types are given in other fields. However, users are responsible for selection of data for their specific purposes. Definitions of screening codes and additional data quality notes are provided in the tables below.
