Often environmental contaminants, like estrogenic compounds, do not readily degrade when they are adsorbed to soil particles (adsorption can make these compounds unavailable to microbial organisms largely responsible for their decomposition). If a 1850 kg mass of soil contained 0.25 m3 of water with a dissolved compound concentration of 15 mg/L, how much mass of this compound would remain after 30 days? The compound has a half life of 22 days at a temperature similar to that in your study situation. You may make the following assumptions: the compound follows the Freundlich adsorption model with K = 0.25 L/kg and n = 1.2 any compound adsorbed to soil particles is resistant to degradation adsorption is at equilibrium at the beginning of the 30 day period the compound does not easily desorb
