Project report on a comparison and analysis of macroinvertebrate community health between the Tyson and Alcan branches (Pettis Co., Missouri)

Abstract

The Central Plains Center for Bioassessment (CPCB), a non-regulatory, non-management research organization established to provide biological expertise for the Central Plains and United States Environmental Protection Agency Region 7, was asked to participate in the analysis of invertebrate samples from the Alcan and Tyson Branches in Missouri in order to identify possible impact. Samples were sorted, identified and analyzed in a double blind manner in which we were not involved in sampling or aware of sampling methods. Conversely, field personnel from the Missouri Department of Natural Resources have not participated in identification and analysis. Herein, we report on the results of this study.
