Petroleum Hydrocarbons

Regulatory Method Challenges for Petroleum Hydrocarbons

Until the mid-1980s, most underground storage tanks were made of bare steel, which is likely to corrode over time and allow contents to leak into the environment.  Faulty installation or inadequate operating and maintenance procedures also can cause releases into the environment. Sources of petroleum hydrocarbons in the environment can arise from leaking underground storage tanks (USTs) and spills of gasoline, diesel fuel, aviation and other fuels.  It is often important to understand the source of the petroleum hydrocarbons on a site prior to remediation.  Several options are available to quantify petroleum hydrocarbon levels in a sample including:

  • Gasoline Range Organics (GRO) by method 8015 - A purge and trap method to quantify the level of hydrocarbons in the C6-C10 range.
  • Diesel Range Organics (DRO) by method 8015 - A gas chromatography (GC) method utilizing a flame ionization detector to quantify hydrocarbons in the C10-C28 range.  Several labs in our network can also report an extended range to C40.
  • Several states have developed their own TPH testing methods including NWTPH (Washington), TX 1005/1006, NJEPH, CTETPH, AK 102/103, TN EPH/GRO, FL PRO.  TestAmerica routinely provides these and many other state specific TPH methods.

TestAmerica offers a diverse range of EPA and state required hydrocarbon testing methods as well as testing for incident response services.  Methods include, but are not limited to:
