A High Resolution Passive Flux Meter Approach Based on Colorimetric Responses

Abstract

The standard Passive Flux Meter (PFM) is a well-established device used for measuring groundwater and contaminant mass flux in screened wells. The PFM is a permeable device that contains granular activated carbon impregnated with alcohol tracers which is deployed in a flow field for a designated period of time and requires laboratory analysis to quantify Darcy flux. To expedite test results, a modified PFM based on the visual analysis of colorimetric responses, herein referred to as a colorimetric Passive Flux Meter (cPFM), was developed. Various dyes and sorbents were evaluated for their ability to determine colorimetric response to water flow.
