The document analyzes the effect of fertilization and environmental factors on water quality in the Upper Cove River Watershed. It tests variables like nitrate, temperature, dissolved oxygen, pH, and conductivity at various sites over time. The hypothesis is that nitrate levels will be higher in the east tributary flowing from a golf course and water quality will improve after passing through marsh areas. Testing found nitrate was higher in the east tributary and decreased after wetlands, while dissolved oxygen was higher in the west tributary. pH was lowest in late October and highest in early January.
