Comparison of NSZD Characterization methods

A 2015 remediation project on an LNAPL-contaminated site compares different methods to measure NSZD rates.

The project concludes that among all methods tested for NSZD rate measurement, the CO₂ traps rank best in the areas of capital costs, data reliability, and ease of use.

This study also highlights the variable nature of short term soil gas fluxes and the importance and reliability of the radiocarbon correction on the total CO₂ fluxes to quantify NSZD rates.
