Two environmental remediation technologies that lend themselves well to being combined in a single application are In Situ Chemical Oxidation (ISCO) using activated persulfate (PS), and In Situ Stabilization (ISS). Persulfate can be activated by increasing the pH to 10.5 and/or increasing temperatures to 30ºC. Many common ISS amendments increase temperature to 30°C and/or pH to 10.5 when in contact with soil water. Laboratory experiments were conducted with various soils to determine the ability of eight ISS amendments to activate persulfate. All eight ISS amendments activated persulfate. This work also showed that the relative contribution of heat vs. alkaline activation …
