"In this study, a new approach has been taken to evaluate Saint John River water and sediment conditions. A battery of biochemical, microbiological and bioassay tests were used to identify degraded or degrading sediments and waters. Data were obtained from waters and sediments at 38 sites within the Saint John River Basin. The data suggested that the following four sites had the highest priority concern: Little River #34, Grand Bay, Saint John River near Boars Head #33, Madawaska River below mill #7 and St. Francois-de-Madawaska, mill stream #2. The data also indicate that microbial population, biochemical or bioassay tests performed independently do not provide realistic estimates of priority concern areas and that the "battery of tests" approach is necessary to provide management with information on which decisions can be made"--Abstract.
