Woburn Model AnimationThis 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. This animation, courtesy of Ohio State University, is available for download at: http://www.geology.ohio-state.edu/courtroom/animations.htm. A detailed explanation of the animation by E. 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, 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,

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. This image, courtesy of Ohio State University,
