  • Preliminary investigation of microbial indicators in the assessment of Oregon streams

    Creator:
    Campbell, Heidi M. K.
    Abstract:
    The Environmental Monitoring and Assessment Program (EMAP) site selection protocol was used to generate a random sample of streams throughout the state of Oregon. One hundred and forty-six selected streams were sampled during the summer, low-flow period of 1997. Traditional microbial public health indicators, including heterotrophic plate counts (HPC), total...

    Pennington, Alan Travis
    Abstract:
    Traditional public health bacterial indicators of water quality and the Biolog® system were evaluated to compare their response to other indicators of stream condition with the state of Oregon and between ecoregions (Coast Range, Willamette Valley, Cascades, and Eastern Oregon). Forty-three randomly selected Oregon rivers were sampled during the summer...

  • Evaluation of bacterial community indicators of stream sanitary and ecological condition

    Creator:
    Bracken, Caragwen L.
    Abstract:
    The focus of this research was to develop bacterial community indicators of stream sanitary and ecological condition. The first study compared substrate utilization patterns between centrifuged and uncentrifuged split samples. We found a shift in the relative proportion of each group of bacteria following centrifugation, with a marked increased in...
