H2A’s Mike Hawthorne Coauthors NAPL Article in Ground Water Monitoring & Remediation on Identification of Confined and Perched NAPL

written by Andrea

Confined LNAPL Eq and NonEQ DiagramH2A’s J. Michael (Mike) Hawthorne, PG, coauthored an article recently published in Ground Water Monitoring & Remediation titled “Identification and Assessment of Confined and Perched LNAPL Conditions.”  Coauthors include Andrew Kirkman and Mark Adamski of BP Americas.  The article presents powerful tools that use routinely collected data to identify confined or perched LNAPL.  Routinely collected data includes gauging data, boring logs, visual observations of soil cores, LNAPL baildown testing, and where available – laser induced fluorescence data.  Identification of the correct LNAPL hydrogeologic condition results in more accurate LNAPL conceptual site models, improved estimates of LNAPL recovery rates and volumes, more appropriate technology applications, and improved accuracy of LNAPL remediation metrics such as LNAPL transmissivity.  The article is available at the following link:
