Data
		Turbidity at Bird Bridge was relatively high. This could possibly be due to soil runoff from nearby farms. In general turbidity went up at the river sites but down at Bird Bridge.
Analysis of River Sites

Analysis of All Samples

		Total Dissolved Solids for the river sites all went down between the two visits. Perhaps the rain water diluted the river’s TDS between visits.




		The Phosphate levels for two of the three sites increased. A reason for this may have been from the fertilizer runoff by nearby farms at both the sites. As for Dam River, this could have been an error in our data.




		Looking at each site the dissolved oxygen level either stayed the same or dropped. Some possibilities for this could be from nearby farm’s herbicide runoff killing the underwater plant life, or a great burst of aquatic life eating the plant life.




		At Bird Bridge the pH stayed the same in both visits, but at the other sites the pH decreased by a half. This could’ve happened from the rain since the rain water had a pH of 6.5. Mixing this rain water with the river water made the two site’s pH levels decrease.



		There is no nitrate graph because the river had very little
		nitrate in it, with one exception - Bird Bridge. In this case
		nitrate levels went up due to farm runoff.
