The Village Square Condominiums homeowners association will vote Thursday night on whether it will grant a federal agency permission to test the groundwater flowing beneath the property.
The condominium complex borders a 500-acre pool of severely contaminated groundwater that is part of the Raymark Superfund site. The Environmental Protection Agency wants to test the water under the complex to make sure the contaminated water does not extend beyond boundaries originally assigned to it by regulators.
But the EPA needs permission from residents before it can move forward with plans to install two to four groundwater monitoring wells on the property and test the indoor air quality.
“The real objective here is to just be able to better delineate the outer edge of the plume,” Ron Jennings, a longtime EPA project manager, told the Connecticut Post earlier this month. “We think we’ve got it, but it would be nice to have a higher level of confidence.”
The contaminated groundwater here is not used for drinking. But it releases a toxic gas that permeates the soil and disperses into the air. The gas can enter homes through plumbing gaps and cracks in the foundation. When trapped within four walls, the toxins become concentrated and potentially hazardous to breathe.
If the EPA finds contaminated groundwater beneath the condominiums, the property would likely be adopted into the Superfund program, Jennings said.
But, he added, regulators do not think the groundwater under the condo property is contaminated.
If the project wins approval from homeowners, new wells would be installed over the course of about a week. Groundwater test results would be available about one or two months after installation, Jennings said.
Indoor air sampling would take place over a 24-hour period and results would be available in about a week, he said.
