Two different streams were tested for this project, one in an urban area, and one in a rural area. Urban areas and rural areas have very different land uses, so this project will allow insight on the effect that land use has on its local streams. The first stream studied was the Kenduskeag Stream which is in a more urban setting, tested within the city limits of Bangor. The second stream was Little Birch Stream in Milford which is in a rural area located within the Sunkhaze National Wildlife Refuge. Water quality was assessed using both biological and chemical methods, including insect sampling, chlorophyll-a analysis, and water nutrient sampling for nitrogen and phosphorus. These methods helped to provide quantitative and qualitative data to determine the direct impacts of land use on water quality. Through use of the Hilsenhoff Biotic Index, the aquatic insects found in Kenduskeag Stream are more tolerant to organic pollution than the insects living in Little Birch Stream which are more intolerant to organic pollution. Chlorophyll-a trends for late summer show an average concentration of about 0.02 mcg/m2 for Little Birch Stream and 0.09 mcg/m2 for Kenduskeag Stream, indicating higher human influence at the urban site. Data suggests there are water nutrient differences between the two sites. Between insect and chlorophyll-a analysis, Kenduskeag Stream shows that it could be impacted by pollution due to human influence, while Little Birch Stream shows little to no evidence of pollution due to human influence.en-USAbstract
