Due to the non-selective characteristics of oxidants, three aspects concerned for estimating ISCO oxidant dosage requirement for effective treatment of target contaminants must be considered: the stoichiometric amount of oxidant for destroying the contaminant, the oxidant demand to meet with the consumption by natural soil oxidizable matters and the amount resulting from oxidant self-decomposition. It should be noted that the oxidant consumed by the background organic and inorganic components of the soil aquifer matrix is known as soil oxidant demand of the treatment zone.

由於大多数氧化剂不具选择性，因此若欲使目标污染物达到良好的降解效率，必须考量目标污染物所需之氧化剂剂量、氧化剂本身自我降解量，以及与土壤中其他可氧化物质（oxidizable matter，OM）反应之消耗量，此三者综合才是真正现地应用所需之氧化剂总量，而用以克服土壤中非目标OM之氧化剂量称为土壤氧化剂需求量（soil oxidant demand，SOD）。
