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
be 0.05 m.
