Description of Data Sets Collected as Part of the ACF River Basin Study

Data collected as part of the ACF River basin study are presented by project component: surface-water, ground-water, special studies, streamflow, ancillary, and quality assurance data. The water-quality data are presented by major headings, including water-column, bed-sediment and tissue, and biological. The data are further subdivided into data sets consisting of related constituents. Data tables can be viewed on the users computer screen or retrieved to a users computer as a tab delimited Relational Data Base (RDB) file. To reduce the size of the pesticide, volatile organic compound, bed sediment and tissue, and trace element tables, only those compounds found equal to, or above the minimum reporting limit (MRL) for one or more sites within a group, are shown. The remaining compounds were not detected. A complete list of constituent names and MRL's are available.

To get more information about available data for a project component, select the componet of interest:
  • Surface Water
  • Ground Water
  • Special Studies
  • Streamflow
  • Ancillary (not available)
