Officials say contamination from a former dry-cleaning business is being cleaned up from beneath a Bennington shopping plaza.
The Vermont Department of Environmental Conservation says a chemical oxidizer will be added to the ground to get rid of the contaminants.
Officials say a dry-cleaning business leaked a chemical known as PCE at the Monument Shopping Plaza in the 1970s and 1980s.
That contaminated groundwater.
The Environmental Protection Agency says it spent about $1 million to make sure 14 nearby homes had drinking water. But the site was never cleaned up.
The state now has negotiated a settlement with the former and current owners of the plaza and the dry cleaning business to cover the cleanup costs.
