The area that is being looked at is in north Dayton near the old Chrysler factory, which is now the Behr Dayton Thermal Products plant.
Scientists are checking to see how chemicals that were leaked many years ago are on the move underground.
Eileen Bennett has lived in the neighborhood for more than 40 years. She has seen some homes being retrofitted with pipes to exhaust any potential hazardous fumes from underground contamination.
News Center 7’s Jim Otte said scientists have tracked the original source of the contamination years ago to one part of the old plant and now it is spreading underground in several different directions.
The state Environmental Protection Agency is mapping that spread with new data, so they are collecting from wells.
Water samples are being drawn and then they will be analyzed to see how much, if any, contamination has spread.
Most of the technology for this kind of testing has been around only for the last 10 years or less. So, the EPA is hoping to get a much clearer picture of the problem.
The EPA said they should have the results in a few months. They will then have a better picture of where the contamination has spread and what can be done about it.
