Mass Discharge and Mass Flux Short Course

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.

The short course presented in December 2010 at the SERDP and ESTCP Symposium covers how mass information can improve contaminated site management. The course is based on the technology overview document, Use and Measurement of Mass Flux and Mass Discharge, published by the Interstate Technology & Regulatory Council (ITRC). Available measurement and estimation techniques are described, and several case studies of mass flux measurements at contaminated sites are examined.

The material in its entirety is covered in the PDF file. The original training was recorded as a series of Adobe Flash videos, as shown below. Since browsers no longer support Flash, this information is provided solely for reference.
