7.19. Wastewater containing 2.01 g/m² of pesticide percolates through a soil treatment system. Adsorption has been determined to follow a Langmuir isotherm with a = 1.01 and b=0.003 mg. Determine the mass of pesticide that will potentially accumulate in the soil if the cross-sectional area is 20 m² and the depth is 4 m. The dry density of the soil is approximately 2400 kg/m³.

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.
