Table 2. WIAC results compared with AP -42 defaults. WIAC-1 values use AP42 averaging methods. <br />Rome WIAC-2 values, grayed in column 2, use different methods (see text). <br />Carbon Tetrachloride was detected at one codisposal site but at none of 35 MSW -only disposal sites. <br />5 <br />WIAC <br />Concentration, 3ipmv <br />Compound <br />Sites <br />AP -42 WIAC-1 <br />WIAC-2 <br />1,1,1 -Trichloroethane (methyl chloroform) <br />46 <br />0.48 <br />0.168 <br />0.168 <br />1,1,2,2 -Tetrachloroethane <br />19 <br />1.11 <br />0.070 <br />1, 1 -Dichloroethane (ethylidene dichloride) <br />45 <br />2.35 <br />0.741 <br />0.741 <br />1,1-Dichloroethene (vinylidene chloride) <br />45 <br />0.2 <br />0.092 <br />0.092 <br />1,2-Dichloroethane (ethylene dichloride) <br />47 <br />0.41 <br />0.120 <br />0.120 <br />1,2-Dichloropropane (propylene dichloride) <br />17 <br />0.18 <br />0.023 <br />2 -Propanol (isopropyl alcohol) <br />3 <br />50.1 <br />7.908 <br />7.908 <br />Acetone <br />8 <br />7.01 <br />6.126 <br />Acrylonitrile <br />3 <br />6.33 <br /><0.036 <br /><0.036 <br />Benzene (Co -Disposal) <br />3 <br />11.1 <br />10.376 <br />10.376 <br />Benzene (No Co -Disposal) <br />44 <br />1.91 <br />0.972 <br />0.972 <br />Bromodichloromethane <br />7 <br />3.13 <br /><0.311 <br />JM� <br />Carbon disulfide <br />31 <br />0.58 <br />0.320 <br />Carbon tetrachloride <br />37 <br />0.004 <br /><0.007* <br /><0.007* <br />Carbonyl sulfide <br />29 <br />0.49 <br />0.183 <br />0.183 <br />Chlorobenzene <br />46 <br />0.25 <br />0.227 <br />.0.227 <br />Chlorodifluoromethane (Freon 22) <br />1 <br />1.3 <br />0.355 <br />0.355 <br />Chloroethane (ethyl chloride) <br />21 <br />1.25 <br />0.239 <br />Chloroform <br />45 <br />0.03 <br />0.021 <br />Chloromethane <br />8 <br />1.21 <br />0.249 <br />Dichlorobenzene <br />34 <br />0.21 <br />1.607 <br />Dichlorodifluoromethane (Freon 12Y <br />19 <br />15.7 <br />1.751 'Ii <br />Dichloromethane (Methylerie Chloride) <br />47 <br />14.3 <br />3.395 <br />3395' <br />Dimethyl sulfide (methyl sulfide) <br />34 <br />7.82 <br />6.809 <br />i'.6 809 <br />'Ethane <br />1 <br />889 <br />7.943 <br />7.943 <br />Ethanol <br />4 <br />27.2 <br />118.618 <br />Ethyl mercaptan (Ethanethiol) <br />36 <br />2.28 <br />1.356 <br />Ethylbenzene <br />26 <br />4.61 <br />6.789 <br /><0.046 <br />6.789 <br />MW I <br />Ethylene dibromide <br />30 <br />0.001 <br />IN <br />Fluorotrichloromethane (Freon 11) <br />25 <br />.0.76 <br />0.327 <br />0.327 <br />Hexane <br />4 <br />6.57 <br />2.324 <br />Hydrogen sulfide <br />40 <br />35.5 <br />23.578 <br />23.578 <br />Methyl ethyl ketone <br />8 <br />7.09 <br />10.557 <br />Methyl isobutyl ketone <br />7 <br />1.87 <br />2.49 <br />0.750 <br />1.292 <br />0.750 <br />Methyl mercaptan <br />36 <br />Perchloroethylene (tetrachloroethylene) <br />48 <br />3.73 <br />1.193 <br />1.193 <br />Propane <br />1 <br />11.1 <br />14.757 <br />19.858 <br />Toluene (Co -Disposal) <br />3 <br />165 <br />37.456 <br />37.456 <br />Toluene (No Co -Disposal) <br />43 <br />39.3 <br />25.405 <br />25.405 <br />trans -1,2 Dichlorethene <br />1 <br />2.84 <br />0.051 <br />0.051 <br />Trichloroethylene (trichloroethene) <br />48 <br />2.82 <br />0.681 <br />0.681 <br />Vinyl Chloride <br />46 <br />7.34 <br />1.077 <br />1.077 <br />Xylenes <br />45 <br />12.1 <br />16.582 <br />16.582 <br />+i -++i- r--nn„nrl waa dPtP.&Pd <br />at none of <br />the WIAC sites. <br />Carbon Tetrachloride was detected at one codisposal site but at none of 35 MSW -only disposal sites. <br />5 <br />
