Abstract: Common Errors and Misconceptions in the Interpretation of Hydrocarbon Site Assessment Previous HitDataNext Hit

Michael Flack, Donald L. Marcus

Common errors and misconceptions in the interpretation of hydrocarbon site assessment Previous HitdataNext Hit can result in the incorrect use of Previous HitdataNext Hit and inefficiently spent remediation money. Thousands of hydrocarbon impacted sites are assessed each year in the United States. Scores of samples are collected and analyzed from each site by a variety of Previous HitfieldNext Hit and laboratory methods. The Previous HitdataNext Hit are evaluated and decisions are made regarding the nature and extent of impact and the appropriate approach for the remediation of these sites. In many cases an inappropriate decision is made because either the wrong Previous HitdataNext Hit is collected or the Previous HitdataNext Hit is incorrectly interpreted. Through the understanding of the limitations of the laboratory methods and misconceptions regarding Previous HitdataNext Hit interpretation, the site remediation can e improved for the mutual benefit of the party paying the bill and the environment.

Hydrocarbon analytical procedures that are commonly misused, subject to misconceptions or misinterpretations include U.S. EPA Methods 418.1, 8010, 8020, 8015M (purgeable and extractable), and 8260. For Previous HitexampleTop, method 418.1 can detect carbon-bearing compounds such as humic and fulvic acids resulting in spurious reports of concentrations of hydrocarbons.
