The Alaska Methods

AK101   Gasoline Range Organics
This method is designed to measure the concentration of Gasoline Range Organics (GRO) in water and soil. This corresponds to an n-alkane range from the peak start C6 to the peak start of C10 and to a boiling point range between approximately 60 ° C and 170 ° C. This range is also known as Volatile Petroleum Hydrocarbons (VPH) in some states.
Check sheets for reviewing AK101 data: Sample Results and QA/QC.


AK 102    Diesel Range Organics
This method is designed to measure the concentration of Diesel Range Organics (DRO) in water and soil. This corresponds to an n-alkane range from the peak start C10 to the peak start of C25 and to a boiling point range between approximately 170 ° C and 400 ° C. This range is also known as Extractable Petroleum Hydrocarbons (EPH) in some states.
Check sheets for reviewing AK102 data: Sample Results and QA/QC.

AK103    Residual Range Organics
This method is designed to measure the concentration of Residual Range Organics (RRO) in soil. This corresponds to an n-alkane range from the peak start C25 to the peak end of C36 and to a boiling point range between approximately 400 ° C and 500 ° C.
