Persulfate Soil Oxidant Demand - PSOD Starter Kit

The Oxidation Systems PSOD Starter Test Kit provides everything necessary to conduct 10 soil oxidant demand (SOD) tests of soil and groundwater using persulfate as the oxidizer. These simple to use tests provide site-specific data to evaluate the feasibility of using in-situ chemical oxidation (ISCO) to remediate soil and groundwater. The starter kit  includes a high precision electronic balance that provides accurate and repeatable analytical results and all glassware and reagents required for ten tests. A CD is provided with instructions for conducting the SOD test, a spreadsheet to calculate the results, and a sample analytical report that summarizes the test procedure and results. Purchase additional tests as needed with our SOD test kits.

In-situ chemical oxidation using persulfate is an established remediation technology for the treatment of chlorinated solvents such as tetrachloroethene (PCE) and trichloroethene (TCE), VOCs, SVOCs, and petroleum hydrocarbons. The soil oxidant demand, also known as natural oxidant demand, has been determined by USEPA to be the most important criteria in the overall success of an ISCO remedy. Oxidation Systems designed this simple to use and very effective SOD test to provide a screening level measurement of this important parameter.

SOD testing results are reported in units of g/kg (g of persulfate consumed per kg of soil). Although this test is qualitative in nature, the results can be used alone or in combination with site characterization data to estimate the quantity of sodium persulfate required to remediate a given contaminated aquifer. This simple and inexpensive SOD test is a good screening level tool that can provide a “go / no-go” decision to aid remediation designers and stake-holders who are considering ISCO for a particular site.
