New Jersey last week set its safe drinking water standard for the chemical PFOA at 14 parts per trillion, 30 percent lower than Vermont's standard.
After PFOA showed up in private wells in Bennington, Vermont regulators set the limit at 20 ppt, then one of the lowest standards in the country.
Limits on PFOA – a key ingredient in Teflon, Gore Tex and a variety of high-tech plastics – aren't set by the U.S. Environmental Protection Agency.
Key takeaway: A state like New Jersey has more resources to put together its own science investigations, while Vermont relies on Environmental Protection Agency studies. Scientists in New Jersey settled on the lower standard after years of research.
