| Abstract |
Results of a water-quality investigation of the upper Shoal Creek Basin in southwestern Missouri indicate that concentrations of total nitrite plus nitrate as nitrogen (NO2t+No3t) in water samples from Shoal Creek were unusually large (mean of 2.90 mg/L (Milligrams per liter), n (sample size)=60) compared to other Missouri streams (mean of 1.02 mg/L, n=1,340). A comparison of instantaneous base-flow load to NO2t+NO3t indicates that at base-flow conditions, most NO2t+NO3t discharged by Shoal Creek is from nonpoint sources. Nearly all the base-flow instanteous load of total phosphorous as P (Pt) discharged by Shoal Creek can be attributed to effluent from a municipal wastewater treatment plant. Samples collected from a single runoff event indicate that substantial quantities of Pt can be transported during runoff events compared to base-flow transport. Only minor quantities of NO2t+NO3t are transported during runoff events compared to base-flow transport. |
