Sites impacted by light non-aqueous phase liquid (LNAPL) present unique challenges for site management and remediation. LNAPL transmissivity is the preferred metric by industry professionals for use at sites impacted with LNAPL to satisfy the “maximum extent practicable” recovery criteria rather than relying on measured apparent LNAPL thickness in wells. LNAPL transmissivity is a consistent and universal metric for analyzing LNAPL hydraulic recoverability and it provides a discrete numerical value that: (1) has nationwide regulatory precedent and acceptance; (2) has been confirmed and/or endorsed by a number of researchers; and (3) can indicate a point at which recovery (or further recovery) of LNAPL may be considered “infeasible.”  Collecting LNAPL transmissivity measurements can be done with recovery data analysis and a variety of field tests. GEI will cover the basics of LNAPL transmissivity field testing/analysis, method applicability, national regulatory acceptance, and practical case studies.

 

Speakers:

Tom Daigle, P.G., Environmental Project Manager at GEI Consultants

Camille Carter, Senior Geologist at GEI Consultants

 

Tom Daigle leads GEI’s LNAPL transmissivity testing practice and specializes in both the field testing procedures and analysis methods for LNAPL sites.  He has been with GEI over 10 years working on a wide range of environmental projects and supporting GEI’s civil and geotechnical engineering services.  

Camille Carter has been working in LNAPL remediation since 2006 and specializes in risk-based LNAPL site management, Conceptual Site Model (CSM) development, and 3D modeling. She has been with GEI for a year, and previously worked for AECOM.

 

Lunch will be provided.  Please indicate if you will need a special meal on your registration.
