PFAS in the water supply is a national water quality issue. Reduce your risk of exposure to these chemicals by using bottled water or other licensed drinking water that has been tested for these chemicals or that uses a treatment that removes these chemicals (specifically activated carbon or reverse osmosis). Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are man-made chemicals, are resistant to heat, water and oil, and persist in the environment and the human body. EPA has found ways to remove PFAS from drinking water. PFAS are not found naturally in the environment. An official website of the United States government. However, these compounds remain in the human body for years after exposure and in the environment for longer, so it will be a long time before they disappear from blood. The group contains several categories and classes of durable chemicals and materials with properties that include oil, water, temperature, chemical and fire resistance, as well as … Therefore, EPA researchers have been studying a variety of technologies at bench-, pilot-, and full-scale levels to determine which methods work best to remove PFAS from drinking water. Decades of heavy use have resulted in contamination of water, soil and the blood of people and animals in the farthest corners of the world. The most commonly found and best studied PFAS are perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS). EPA has established health advisories for PFOA and PFOS based on the agency’s assessment of the latest peer-reviewed science to provide drinking water system operators, and state, tribal and local officials who have the primary responsibility for overseeing these systems, with information on the health risks of these chemicals, so they can take the appropriate actions to protect their … Following Canada’s footsteps, the EPA established the Health Advisory levels for PFOS and PFOA at 70 parts per trillion. They pose a cancer risk. If you must use a humidifier, only use water from a safe source. How much exposure to these substances in clothes, firefighting foam and food wrap is too much? Granular Activated Carbon (GAC) – Chemicals like PFAS stick to the small pieces of carbon as the water passes through. Per- and polyfluoroalkyl substances (PFAS) are a large family of man-made chemicals that contain carbon, fluorine, and other elements. Sometimes called “forever chemicals,” certain PFAS take a long time to break down and can accumulate in the environment, drinking water and in the human body. PFAS are a family of chemicals accumulating in the soil, rivers, drinking water and the human body. PFAS stands for a broad group of perfluoroalkyl and polyfluoroalkyl substances. PFAS manufacturing and processing facilities, airports, and military installations that use firefighting foams are some of the main sources of PFAS. Find out more using EPA's Treatability Database. Studies show that human exposure to PFAS is widespread and most people in the United States and in other industrialized countries have measurable amounts of PFAS in their blood. The chemicals, estimated to be in the drinking water of over 110 million people Americans, are linked to cancers and low infant birth rates. While some PFAS chemicals are no longer in use, they are hard to breakdown and can accumulate over time. Young children have a higher risk of exposure to PFAS from carpet and cleaning products, largely due to time spent lying and crawling on floors in their early years. Unborn babies can be exposed to PFAS through umbilical cord blood from their mothers during pregnancy. Breastfeeding is associated with numerous health benefits for infants and mothers. The different PFAS have different lengths and/or differ in their properties at one end, which can change the toxicity of the chemicals. PFAS stay in the human body for long periods of time. If you have compost from last year’s gardening, use that in other areas of your yard. Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have been in use since the 1940s, and are (or have been) found in many consumer products like cookware, food packaging, and stain repellants. There are a few things you can do to further reduce potential exposure: Water System Information (Drinking Water Watch), Consumers of Public Water During Emergencies, Atlantic States Rural Water & Wastewater Association, State Drinking Water Administrators Association, Basic Information about Per- and Polyfluoroalkyl Substances (PFASs), Official Website of the State of Rhode Island, public water systems and drinking water wells, soil, and outdoor air near industrial areas with frequent PFAS manufacture, disposal, or use, indoor air or dust in spaces that contain carpets, textiles, and other consumer products treated with PFAS to resist stains, surface water (lakes, ponds, etc.) These chemicals have been in use since the 1940s and are found in a variety of products including firefighting foams, household products such as non-stick cookware, food packaging, and stain and water repellants. Water your garden and seedlings with a clean source of water. Although more research is needed, some studies have shown that long chain PFAS like PFOA and PFOS may: The toxicity of shorter PFAS is currently not well understood, although they remain in the blood for shorter periods of time. PFAS are incredibly persistent, never breaking down in the environment and remaining in our bodies for years. 66 water supplies serving 6 million people had at least one water sample at or above the EPA’s safety limits. The health effects on animals are similar to the effects on people. PFAS also dissolve in water, and combined with their chemical properties mean traditional drinking water treatment technologies are not able to remove them. In Hyannis, Massachusetts, firefighting foam from a firefighter training academy is the likely source of well-water contamination, according to the state. With widespread use of the chemicals in many foods, common household goods, wildlife, and industry processes, it’s hard to avoid. In the UCMR3, there were six PFAS included for monitoring including: perfluorooctanesulfonic acid (PFOS) perfluorooctanoic acid (PFOA) Powdered Activated Carbon (PAC) – The … In fact, it is unlikely that anyone, even if they did not drink contaminated water, will have a level of “zero” PFAS in their blood. EPA has found ways to remove PFAS from drinking water. The fat and water repelling properties of these substances allowed them to be applied to almost any material to make it water, oil, and stain repellant. PFAS can be found in blood, and at much lower levels in urine, breast milk and in umbilical cord blood. These properties were first used commercially in the 1950s, and they are used in a wide variety of consumer products, including carpets, clothing, non-stick pans, paints, polishes, waxes, cleaning products, and food packaging. Some, but not all water filters, can remove PFAS to the EPA’s advisory level of less than 70 ppt. Some types of PFAS are absorbed into plants, but can be flushed out of soil with clean water. We cannot accurately predict what health effects individuals may experience if they are exposed to PFAS. more. PFAS are used in a staggering array of consumer products and commercial applications. Studies have shown that gardens watered with PFAS-contaminated water will have higher levels of PFAS in the soil. Older children may be exposed to PFAS through food, water, and other products, similar to adults. DO NOT boil your water. If people ingest PFAS (by eating or drinking food or water that contain PFAS), the PFAS are absorbed, and can accumulate in the body. Boiling water will concentrate these chemicals. According to the Environmental Working Group, or EWG, a public health advocacy organization that has called for more regulation of PFAS, the gold standard for in-house filtration … Newborns can be exposed to PFAS through breast milk or through formula made with water that contains PFAS. Higher levels can be found in water supplies near facilities that manufactured, disposed, or used PFAS. The science on the health effects of PFAS for mothers and babies is evolving. As a precaution, you may consider shorter showers or baths, especially for children who may swallow water while playing in the bath, or for people with skin conditions (rashes, cuts, etc.). The draft ATSDR estimate is lower than the EPA number because they made different decisions on how to predict human toxicity from animal studies, but both include significant safety margins to account for uncertainty. It is a class of chemicals that can wreak havoc on your health and that of your family. lower a woman’s chance of getting pregnant, increase a woman’s blood pressure during pregnancy, interfere with the body’s natural hormones. PFAS may be released into the air, soil, and water, including sources of drinking water. Tests reveal “PFAS” contamination in 40 Town of Campbell private wells The city of La Crosse is offering bottled water to residents whose wells tested high for PFAS … Firefighters and the military use them in fire-suppressing foam. Studies have shown that gardens watered with PFAS-contaminated water will have higher levels of PFAS in the soil. These areas of PFAS contamination include public drinking water systems supplying water for an estimated 19 million Americans. The decontaminated water is returned to the environment, normally in a surface water reservoir such as a lake. The Rhode Island Department of Health recommends taking the following steps to minimize risk: Routine showering, bathing, or swimming are not a major source of exposure to PFAS. In Decatur, Alabama, a 3M manufacturing facility is suspected of discharging PFAS, polluting residents’ drinking water. The presence of per- and polyfluoroalkyl substances (PFAS) in drinking water throughout the U.S. has been the source of much public outrage, drinking water treatment effort, and legislation. Doing laundry or washing dishes are also not a major source of exposure to PFAS. Wash your produce in clean water after you harvest it. There are things to consider with each of these technologies, including costs and operational feasibility, that would need to be weighed by the needs of the community. Parents of formula-fed infants may consider using a formula that does not require adding water. PFAS do not readily breakdown in the environment and are water soluble. Prenatal care is important for all pregnancies. Scientists are still learning about the health effects of exposures to PFAS. The Philadelphia Water Departmentstates that it is “proactively testing for PFAS in source water and has not detected concentrations above EPA’s advisory level.” EWG’s tests of Philadelphia water show total PFAS concentrations at nearly 50 ppt. Common refrigerator filters or filters found in pitchers, for instance, may not have enough carbon or the best type of carbon to reduce PFOA and PFOS. For root vegetables, consider peeling and washing them before eating. US manufacturers of PFAS-related products phased out production of PFOS by 2002 and PFOA by 2013, although US production of shorter chain PFAS continues. The PFAS sticks to the carbon, leaving a toxic residue that must be hauled away and incinerated or dumped into hazardous waste landfills. If you suspect exposure to higher levels of PFAS and you or your family members have signs or symptoms that you think could be related to that exposure, you should talk to your family's healthcare provider. Additional information on PFAS and Drinking Water is available from the Connecticut Department of Public Health (DPH) here . Contaminated water is pumped to the surface and then filtered through activated carbon tanks. If you are pregnant and you think you have been exposed to PFAS, tell your obstetrician, as it may be important to monitor your blood pressure. These technologies can be used in drinking water treatment facilities, in water systems in hospitals, or individual buildings or even in homes. Under the Third Unregulated Contaminant Monitoring Rule (UCMR3), EPA collected data for chemicals that are suspected contaminants in drinking water but do not have health-based standards set under the SDWA.
