Not knowing the source of this fuel and not having a <br /> representative analytical view of its distribution in the subsurface, we believe this is a <br /> conservative interpretation. <br /> The table below also shows the estimated volumes of the other chemicals requested in the March <br /> 9, 1998 letter, as calculated in this-manner. <br /> Sources for the information presented below are: <br /> a GTI's mass estimate calculation spread sheet <br /> a MSDS references pages <br /> a The Merck Index <br /> RC Handbook of Chemistry and Physics <br /> a Introduction of Geochemistry by Krauskopf <br /> Chemical/ Range Range Ave. Solubility Vapor Press <br /> Compound % Volume Volume (mg/L) (mm,HG,*@ <br /> Name (gal) (gal) 25'CQ <br /> TPH-G 95-100 167-205 185 - 300-700 <br /> MTBE 10-20 17-41 29 43,000 250* <br /> Benzene 1-5 2-10 6 1,780 95* <br /> Toluene 3-10 5-20 13 - - <br /> Ethyl Benzene 1-3 2-10 6. -T.
