1、Designation:D583117Standard Practice forScreening Fuels in Soils1This standard is issued under the fixed designation D5831;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates th
2、e year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice is a screening procedure for assessing thepresence of fuels containing aromatic compounds in soils.If asample of the contaminant fuel is available,the concentr
