A presumptive Q. Why is EPA selecting a presumptive rem- • edy at the Tutu site? : • A. The "Tutu Wells Superfund site involves • the contamination of soils and rock with Vola- tile Organic Compounds brVbCs; VQCs are defined as any organic compound which readily dissipates Into the air, EPA has de- veloped several presumptive remedies (i.e. technologies that have been proven at nu- merous similar sites) fertile cleans ' •.Qi« How can the public register concerns they about the selection of:a;presump- (SVE), thermal desorpt!on{ and Incira- Q. Which presumptive re medy will ERA ChoOse^forthi^ particular site? :; A. -ERA intends :to "select soil vapor ex* traction, or ^VE, as the preisumptive rem- :edy for; contaminated soils and rock at the •Tutu site for two reasons, First, this technol-- ogy was; chosen in over two-thirds of the Record of Decisions for Superfund sites where cleanup setection was driven by VOCs. ; And sebondr SVE [effectively treats wastes in- place at a relatively low cost. ; > ; XJ» What Is Soil A^por ExtraQtion? ; A.
