 v When petroleum products, or the waste associated with use of these products, are released into the
   environment, they chemically and biologically interact with the soil, groundwater, and microorganisms.
 v The ratios of these chemicals serve as a fingerprint for the type of product (diesel, gasoline, etc.)
   originally released into the environment.

                         Some of the chemicals found in petroleum products,
                   significant because of their toxicity or their taste and smell are:

                                                              which are potential carcinogens. 17 specific PAHs are

MTBE (Methyl Tertiary Butyl Ether) is a fuel additive which has been used in the United States since 1979. Its
use began as a replacement for lead in gasoline because of health hazards associated with lead. MTBE has
distinctive physical properties that result in it being highly soluble, persistent in the environment, and able to
migrate through the ground. DEP has required the monitoring and cleanup of MTBE at petroleum contaminated
sites since February, 1990, and continues to monitor studies focusing on the potential health effects of MTBE and
other fuel additives. For more information, visit DEP’s Petroleum Cleanup Program web site at:
