ASTM Standard References Multiple Methods for Estimating LNAPL Transmissivity

written by Andrea

ASTM Tn Methoods Basic

ASTM E-2856-11, Standard Guide for Estimation of LNAPL Transmissivity, identifies four primary methods to measure LNAPL transmissivity.  However, one of those four methods, recovery data analysis, has four sub-methods based upon the remediation technology used.  And one of those sub-methods, total fluids recovery data, can be further subdivided based on whether you plan to analyze long-term steady state data or instantaneous ratio test data.  The above chart graphically depicts the four primary methods and the associated sub-methods to create a clear visual picture of the multiple methods available under the ASTM standard.
