H2A Presents “An Exploration of LNAPL Transmissivity” to the USEPA

written by Andrea

Tn Test Method, Scale, & PrecH2A recently presented an in-depth training webinar to the USEPA titled “An Exploration of LNAPL Transmissivity.”  H2A’s Mike Hawthorne identified LNAPL transmissivity as an improved metric (versus LNAPL thickness or recovery data) with respect to LNAPL mobility, recoverability, and remediation operational progress.  Five techniques used to measure LNAPL transmissivity were reviewed in detail and the relative benefits of each method, including a discussion of temporal and spatial scale and measurement precision issues, were presented.  The strategic application of each method was identified and various uses for LNAPL transmissivity were presented including mobility/recoverability characterization, remediation design, and technical impracticability applications, among others.  (Click on graphic to view larger.)
