Mass discharge and flux measurements are being used more frequently to characterize and monitor groundwater contamination. Their use is increasing as a result of several recent improvements in mass flux and discharge measurement methods, as well as a growing recognition that mass flux data can improve conceptual site models and remediation decisions as compared to a reliance on concentration data alone. Mass discharge and mass flux estimates are useful for managing groundwater contamination because they quantify the source or plume strength at a given time and location. These estimates can be particularly useful in addressing complex and difficult sites. 

ON-DEMAND VIDEO AVAILABLE: The on-demand video of this course covers the basic concepts of how mass information can improve contaminated site management. The course was based on the technology overview document, Use and Measurement of Mass Flux and Mass Discharge, published by the Interstate Technology & Regulatory Council (ITRC). The available measurement and estimation techniques were described, and several case studies of mass flux measurements at contaminated sites were examined. Links to the modules are available below. In addition, the material in its entirety is available in PDF format.
