A New Jersey committee has recommended a limit of 14 parts per trillion (ppt) for PFOA in drinking water. That is much lower than the standard New Hampshire is using, 70 ppt.
PFOA is a chemical used in firefighting foam, nonstick cookware, stain-resistant carpeting, and many other products.
The long-term health effects of PFOA are not fully understood. While almost everyone has small amounts of PFOA in their body, some studies suggest long-term exposure is linked to cancer and other health problems.
