A large turnout is expected for a meeting in Merrimack Wednesday night where state officials will update residents on their investigation into the chemical contamination of some local water supplies.
The state Department of Environmental Services has expanded the radius of its probe after three private wells tested for high levels of the chemical PFOA.
DES has now collected samples from approximately 100 private wells within a mile of the Saint-Gobain plastics plant in Merrimack, where the chemical was first detected.
Wednesday's meeting begins at 7 at the James Mastricola Upper Elementary School in Merrimack.
DES spokesman Jim Martin says the meeting will be a chance for residents to get their questions answered.
“We will have staff from DES as well as the Department of Public Health from the state of New Hampshire to give them background on the investigation and what PFOA is.”
Another meeting is scheduled for Thursday night in Litchfield.
