Woburn Model Animation

This animation, based on the Ohio State University plume model of contamination in Woburn, Massachusetts, shows the month-by-month flow of contaminants from various sites around Woburn to two drinking water wells, called wells G and H. The animation begins in January 1960 and continues through May of 1979, when the wells were permanently shut down.

Scott Bair, professor and chair of geological sciences at Ohio State, can be found in the following file: animation_explanation1.doc.


This image, from one of the plausible scenarios suggested by the Ohio State University plume model, shows that by May 1979, the contaminant TCE was being captured by Woburn wells G & H from all five source properties. The cross section view shows that the TCE plumes from the sites of Olympia Nominee Trust (formerly Hemingway Trucking) and the Wildwood Conservation Trust (formerly Beatrice Foods and the J.J. Riley Tannery) flow downward under the Aberjona River to the entrance to well G (bottom of red line, inset). This image, courtesy of Ohio State University, is available for download at:

This image, also from one of the plausible scenarios suggested by the Ohio State University for May 1979, includes a cross-sectional view through well H. The cross-section shows the downward flow of the contaminant TCE under the Aberjona River from the Olympia Nominee Trust site and the downward flow of TCE from the UniFirst and W.R. Grace sites to the entrance to well H (bottom of red line, inset). This image, courtesy of Ohio State University, is available for download at:

This image shows the movement of groundwater to pumping wells that originated as river water. Some of this water flows to one of the industrial wells supplying water to the J.J. Riley Tannery site, and some of it flows to wells G and H. The cross-section shows that in May 1979, about 50 percent of the water pumped by well G was derived from the river.
