DEVELOPMENT OF A PASSIVE FLUX METER APPROACH TO QUANTIFYING 1,4-DIOXANE MASS FLUX
Annable, M.D., M. Miller, and J. Cho.
SERDP Project ER-2304, 87 pp, 2018

The passive flux meter (PFM) was developed at the University of Florida in 2001 to obtain direct measurements of contaminant mass flux and Darcy flux at contaminated sites. Increased error may occur when using PFM where low-partitioning contaminants are involved. The objective of this study was to develop a modified PFM approach to quantifying contaminant flux of low-partitioning contaminants while simultaneously measuring Darcy flux with an acceptable measurement error. Modifications were proposed based on past studies of the passive surface-water flux meter (PSFM) and low-density polyethylene (LDPE) passive diffusion samplers. Designs incorporating modified permeability were tested in box aquifer setups. https://www.serdp-estcp.org/content/download/48564/462173/file/ER-2304%20Final%20Report.pdf
