<br /> Abbreviations&Notes
<br /> TPHg=Total purgeable hydrocarbons as gasoline
<br /> MTBE=Methyl tert butyl ether
<br /> Conc =Concentration
<br /> ppb=Paris per billion,equivalent toµg/L
<br /> µg1L=Micrograms per liter
<br /> L=Liter
<br /> gpm=Gallons per minute
<br /> gal=Galion
<br /> g=Gram
<br /> Mass removed based on the formula volume extracted(gal)x Concentration(gg/L)x(g1166}ig)x(pound/453 6g)x(3 785 Ugal)
<br /> When constituents are not detected,the concentration is assumed to be equal to half the detection limit in subsequent calculations
<br /> Volume removal data based on the formula mass(pounds)x(density)-I(cm31g)x 453 6(g/pound)x(UI000 cm')x(ga1/3 785 L)
<br /> Density inputs TPHg=0 73 glcm',TPHd=0 87 glcm' MTBE=0 74 g/cm'
