There is growing concern for the health of the world’s freshwaters, and bioassessment is often used as a water quality monitoring tool under the Clean Water Act. I used the Surber sampler method to collect aquatic macroinvertebrates from disturbed and undisturbed locations within the Flat Brook watershed in northern New Jersey, USA. %EPT, FBIBI, and functional feeding groups were compared to suggest the overall water quality of each location. Results were not statistically significant; but overall high %EPT and excellent FBIBI values suggest high quality waters within the Flat Brook watershed. These positive ecological results indicate the need to preserve the pristine state of the Flat Brook watershed.
