Yes, most U.S. states now regulate PFAS to some degree. Some, like New Jersey, Michigan, New York, and California, have their own drinking water limits that are often stricter than federal EPA rules. Others are still adopting standards or monitoring requirements. You can check your state’s Department of Environmental Quality (DEQ) or Health Department website for the latest PFAS testing and reporting regulations in your area.
Yes — but only specific filters can effectively remove PFAS. Activated carbon filters, reverse osmosis (RO) systems, and ion-exchange filters are the most reliable methods. Simple pitcher filters or standard sediment filters usually don’t work. For the best results, look for filters certified under NSF/ANSI Standard P473 or P231, which are tested specifically for PFAS reduction.
PFAS exposure has been linked to a range of health concerns, including liver and kidney issues, thyroid problems, immune system suppression, and increased risk of certain cancers. Even low levels of PFAS can build up in the body over time. Because these chemicals are extremely persistent, long-term exposure is a growing public health concern, especially for children and pregnant women.
PFAS are called “forever chemicals” for a reason — they can stay in the human body for years. Depending on the compound, the biological half-life (the time it takes for half of it to leave the body) can range from 3 to 8 years. This means that even small daily exposures can accumulate over time, making prevention and clean water sources especially important.
