Isopropylbenzene? You’re not on the list. Get to the back of the line!

Proper due diligence plays an integral part in the dynamics of real estate transactions. Analysis for EPA Method 8260 for volatile organic aromatics/volatile organic hydrocarbons (VOA/VOH, which includes the contaminants isopropylbenzene, 1,2,4-trimethylbenzene, and 1,3,5-trimethylbenzene, should be standard practice during due diligence but is not a common analysis during assessment and monitoring of FDEP Petroleum Restoration Program funded sites. Initially thought to degrade at the same rate as standard BTEX and MTBE constituents, isopropylbenzene and the trimethylbenzenes have shown to persist longer than these analytes and can have reportable levels even after BTEX/MTBE constituents have decreased below the Groundwater Cleanup Target Levels and the site has been issued a Site Rehabilitation Completion Order (SRCO). Due diligence with analysis for VOA/VOH can prevent delays prior to site acquisition to reduce liability and during construction if encountered during UST closure sampling removal and/or excavation. It can also help determine accurate costs when determining advanced cleanup strategies.
