Storm Sewers and Detention

The storm drains system transports rainwater or stormwater and other runoff from roads, parking lots, and roof downpipes directly to nearby creeks, rivers, or the sea without any treatment.

The herbicide atrazine is accidentally spilled into a river, resulting in 80 μg/L atrazine concentration in the water column at the site of the spill. The intake of a local drinking water supply is located 15 km downstream of the site of the accident. The average river flow velocity is 0.5 m/s and the dispersion coefficient is 50 m2/s. Assuming steady-state conditions in the river and that advection is the dominant transport mechanism, approximately how long will it take for the chemical to reach the drinking water intake? Assume that no transformation of atrazine will occur
