No environmental concerns on Dow site near Zionsville

Phase II investigation shows no contaminants on land

Zionsville — Any worries about environmental concerns on the Dow property are no longer present after a Phase II subsurface investigation was completed.

Brian Wilson, a principal with August Mack Environmental, presented results of the study to the Zionsville Redevelopment Commission Friday. August Mack conducted 22 borings on the site for the Phase II investigation. The boring locations were determined by selecting areas that had the highest probability of having contamination.

“We did not identify any constituents of concern at reporting level above the (Indiana Department of Environmental Management Closure Guide Commercial/Industrial Soil Direct Contact) screening levels,” he said. “In our subsurface samples, we found no chemicals of concern above our lab reporting levels, which are much lower than the screening levels.”

Wilson said they did identify a few metals and other contaminants at the surface level, but all were well below screening levels.

Commissioner Craig Anderson asked if there was anything in the results that may deter a potential buyer.

“No there isn’t,” Wilson said. “The numbers are at a level where IDEM says there is no threat to health or environment. Most of these were within the first foot of soil, so there is some comfort that there is nothing deeper.”

RDC attorney Andy Buroker asked about the flow of groundwater near Remediation Area 2 in the southwest corner of the property, which still has remediation ongoing and is not part of the purchase.

“We reviewed data from wells in the area and installed some wells,” Wilson said. “Our findings were consistent with the data that the groundwater will flow southwest and away from the property.”

Commissioner Luke Phenicie asked what was happening on Remediation Area 2 and how bad the environmental concerns are there.

“I have not reviewed the most recent data, but the concentrations were decreasing,” Wilson said. “The remediation is working in that area, and they are doing some pilot testing on new techniques to help out.”
