"The goal of this study is to observe the values and variability of water quality parameters and benthic macroinvertebrates in watersheds with very little anthropogenic impact and to compare these values with those acquired in watersheds with more anthropogenic impact. The following five HUC 12-digit watersheds had very little anthropogenic impact and were considered "pristine": Rogers Creek, Mill Creek, Middle West Fork-Black River, Bee Fork, and Ottery Creek. Five largely urban sub-basins were also considered; these basins are: Grand Glaize Creek, Glaize Creek, Sugar Creek, Hominy Creek, and Grindstone Creek. For each watershed, both water quality parameters and benthic macroinvertebrates were sampled. The macroinvertebrate samples were used to calculate the biotic index for each stream using the Missouri Department of Natural Resources method, percent Ephemeroptera, Plecoptera, Trichoptera, and the Hilsenhoff Family Biotic Index to help better determine long-term stream health. Water quality parameters were also analyzed to identify seasonal changes and patterns between the streams. Correlation matrices were constructed to determine significant correlations between water chemistry parameters at the pristine steams, the urban streams, and when considering all streams as one sample set. Welch ANOVA was additionally performed to determine which streams were statistically part of the same population. For most water quality parameters, the pristine streams tended to be grouped as one population, while the urban streams were often separated into two populations. The reason for differing populations is most likely related to land use/land cover and varying activities in each watershed"--Abstract, page iii.
