Unformatted text preview: CWR 6537 Subsurface Contaminant Hydrology Homework #5 - Sorption 2 November 2010; Due 10 November 2010 Goals: To understand how solute sorption affects concentration distributions in space and time. Compare analytical and numerical solutions. Over a period of 10 weeks, 25 L of a multi-component organic mixture has been released into an aquifer. We are interested in predicting the transport of the three most hazardous compounds from the release site towards the property boundary, 10 m down gradient. Each component was present in the original mixture at a concentration of 1 g/L. Batch studies have shown that one of the contaminants has negligible sorption in the soil matrix. The other two contaminants are fairly strongly sorbed, with linear isotherms and distribution coefficients of 0.22 and 0.44 ml/g, respectively. The soil has an average porosity of 0.35 and a bulk density of 1.6 g/cm 3 . The average groundwater velocity is 10 m/yr and the dispersivity of the aquifer has been estimated to...
