Can you help me answer this problem, a container of Atrazine (500 g) is dumped into a river 2.3 km upstream of a municipal water intake pipe. Cross-sectional area of the river is 5.7 m2. Assume that the Atrazine is dumped as a point source. The river flow is 8.25m3/s and the longitudinal dispersion coefficient is 0.1 m2/s, what is the maximum concentration (in ppm) expected at the intake. How spread out (in the direction of flow) is the atrazine at the time the peak concentration occurs at the intake pipe? Assume 2 standard deviations on either side of the peak is a good estimate of spread. Thank you

Given, M = 500 gm or 0.5 kg L = 2.3 km or 2300 m A = 5.7 m² Q = 8.25 m³/s D = 0.1 m²/s
