Seymour, Indiana – On June 30th, 2019 Mundell & Associates Senior Technical Director Brent Dayharsh reported to the Seymour Board of Works on progress of the environmental cleanup which is now being proposed as a location for a senior housing development.
Investigation began on the two acre site in 2006 which previously was the site of a woolen mill and later electronics dealer. The initial contaminant of concern was petroleum in the groundwater with chlorinated solvents discovered later and added as goals to achieving site cleanup.
Once Mundell determined size and location of the impacted groundwater plume (the underground reservoir of contamination), soybean oil injection began to mitigate the contaminants in the groundwater. Soybean oil provides a low oxygen environment and carbon food source for the bacteria that will break down the chemicals and ultimately shrink the plume.
Although there are some areas that are not fully cleaned up, the contamination does not pose any threat of migrating through the soil into buildings on the site. Mundell will complete one more round of soybean oil injection this fall.
An Environmental Restrictive Ordinance will be submitted to the Indiana Department of Environmental Management to prevent any wells for drinking water being installed on the property.
