Seymour, Indiana – Senior residents in Seymour, Indiana are looking forward to new housing options next year, thanks to the completion of remediation efforts by Mundell & Associates personnel on a 2-acre property with past petroleum and chlorinated solvent contamination.
The local Seymour paper, “The Tribune” reported last week, that construction on a 64-unit affordable housing complex will begin mid-July.
Investigation began on the 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. Since 2015, there has been more than a 90% reduction in groundwater contamination at the site.
Mundell & Associates was also responsible for successful clean up of the soil on the property through soil excavation and thermal remediation.
Currently a restriction is in place to ban any drinking water wells from being installed on the site. Mundell & Associates will continue to monitor the groundwater for at least another three years to determine if this restriction could be lifted.
Congratulations to Brent Dayharsh, Senior Technical Director and everyone involved in this project!
