Wells-Dawson hetero-metal substituted polyoxometalates (POMs) show potential as effective aqueous decontamination solutions against organic CWA simulants.  Rapid oxidation of the chemical contaminant Demeton-S was achieved with a solution containing both the Zr(IV) substituted Wells-Dawson POM and an in-situ generated tungsten peroxo species.  Evaluations are now performed to investigate the reactivity enhancement afforded by the presence or absence of the Zr(IV) POM species with respect to rapid oxidation of chemical contaminants.  Analysis of the reaction progress and byproducts was performed with LC-MS.  Analysis of the catalytic species in solution was performed via <sup>31</sup>P-NMR and FTIR spectroscopies.  The reactivity assessment of these materials will be evaluated both in solution and as isolated solids in order to target additional applications.<br/>
