The use of contaminant flux and contaminant mass discharge as robust metrics for assessment of risks at contaminated sites, and for evaluating the performance of site remediation efforts has gained increasing acceptance within the scientific, regulatory and user communities. Such gradual increase in acceptance and use of innovative technologies is slower in the environmental community, requiring a sound theoretical basis accepted widely in the technical circles and field- scale demonstration at diverse sites. In 2001 ESTCP funded a project (CU-0114) to demonstrate and validate a new monitoring technology known as the passive flux meter (PFM). This device provides direct in situ measurements of both subsurface water and contaminant fluxes. The focus of this project was to demonstrate and validate the PFM for measuring simultaneously the groundwater and contaminant fluxes in contaminated aquifers. This report presents results of PFM demonstration/validation from a series of controlled field experiments conducted at the CFB Borden Demonstration Site in Ontario, Canada.
