"CONCORD, N.H. -- New Hampshire says emissions of a chemical used to make Teflon coatings may be the source behind the contamination of more than 40 wells in several towns.
The company behind those emissions, Saint-Gobain Performance Plastics, has said it's too early to say whether it's responsible for contaminating wells in Merrimack, Litchfield and Manchester.
So far, the state has determined that 33 wells in Litchfield, seven in Merrimack and one in Manchester contain high levels of the chemical PFOA, suspected by some scientists to be a carcinogen. Some concentrations were four times higher than the levels considered safe by the Environmental Protection Agency.
The state recently told Saint-Gobain it believes the company was "potentially responsible" for the contamination but isn't sure whether the chemicals were dumped into the water or spread through the air."
