dc.description.abstract Three streams with watersheds of different land uses (urban, agricultural, and forested) were chosen for this study. A composite sample of diatoms was obtained from small rocks in a riffle of each stream and identified to genera. Water chemistry measurements included chloride, sulfate, nitrate, conductivity, pH, alkalinity and temperature.Conductivity, chloride, and sulfate were significantly higher in the urban watershed and lowest in the forested watershed. However, the forested watershed had the highest levels of nitrate, which may have come from groundwater or organic matter decomposition. Alkalinity, pH andtemperature did not vary among watersheds.Diatom diversity was significantly higher in the forested watershed. Several diatom genera, Amphora, Cymbella and Gyrosigma, were positively correlated with nitrate and negatively correlated with conductivity, chloride and sulfate, which indicate their potential use as indicators of water quality.
