New Guide for NAPL Mobility and Migration in Sediments: Flux Chamber Measurement of Ebullition Rates and Contaminant Flux

1. Scope

The promotion of knowledge, stimulation of research, and development of standard guides, specifications, practices, test methods, classifications, and definitions relating to environmental assessment, risk management and corrective action. The scope of the Committee includes, but is not limited to multi-media environmental assessment and risk management issues including environmental assessment, environmental management, corrective action due diligence, and sustainability.
These activities will be coordinated with and if available use the standards of other ASTM technical committees and organizations whose fields of endeavor are closely allied to or compliment environmental assessment and environmental management.


NAPL, sediments


Measuring gas ebullition rates from NAPL impacted sediments is critical for understanding short and long term fate and transport of contaminants and for determining appropriate remedial actions. Gas flux chambers can be an important tool for detecting and measuring ebullition rates when designed, deployed, and retrieved properly. Consensus based standards on these concepts do not currently exist and will be quite useful for creating consistency in projects.

The title and scope are in draft form and are under development within this ASTM Committee.
