PFAS Basics 2: Why are PFAS a Health Concern? - YouTube.PFAS Basics 1: What are PFAS? - YouTube.These groups may be especially sensitive to harmful effects of PFAS and drink more water per pound of body weight than most people. Taking action to reduce exposure is especially important for pregnant and breastfeeding people, infants, and young children. You can also use bottled water labeled as “purified” as a short-term alternative. Filters come in different styles and can treat water at your kitchen sink, refrigerator, or in a countertop water pitcher. You can reduce your exposure to PFAS by installing a water filter that reduces PFAS in the water you use for cooking, drinking, and preparing infant formula. How to Reduce Exposure to PFAS in Drinking Water In the future, we will also include water testing data from military testing and other local testing of PFAS in drinking water. If you are near an area with a high PFAS detection, you might choose to test your water source even if you aren't required to test.This view shows where PFAS may still impact a drinking water supply (such as a groundwater aquifer).View the highest historical test result reported for each source.This view helps you understand current conditions in water systems, including any changes in PFAS water concentration after action was taken to reduce levels of PFAS.View the most recent test results for each water system and source.The dashboard also has PFAS testing statistics for commonly asked questions. Click on each dot to see more information about the water system and source. Test results are shown as a map or in the table. Results for all PFAS chemicals from the tests are included in this dashboard. Water systems must use EPA test method 537.1 (18 PFAS analytes) or EPA test method 533 (24 PFAS analytes). If you are concerned about PFAS levels at your home, please call your water system. The dashboard includes results from each source tested within a water system.Ī PFAS detection at a single source doesn’t necessarily mean these levels occur across the water system or at nearby homes. Water is tested after all water treatments are completed (such as disinfection) and before the source water is distributed to water customers. Sources could also be water that flows underground into something called an “aquifer.” An example of a source is a river or a lake. Public water systems must test all active, permanent and seasonal sources of their water supply. The dashboard shows data from PFAS water testing that is required under a 2021 state rule. This can help you decide whether to test your well for PFAS. You can use the map to learn if PFAS have been detected nearby. If you are a Group B water system or a private well owner, you are not currently required by the state to test for PFAS. Some water systems have already taken steps to lower PFAS in their water. Contact your water system to learn more about their response to PFAS. They also show if the levels are higher than our SALs. Testing results show you where PFAS have and haven’t been found in public drinking water sources. While the federal government has not finalized safety standards for PFAS in drinking water, Washington's SALs created rules to inform communities about PFAS in drinking water when it is found. Some types of PFAS could harm human health when they build up to high enough levels in your body. Water systems that find PFAS above a state action level (SAL) must notify their customers within 30 days, and test more often. Testing must be completed by December 2025. The Washington State Board of Health adopted a new rule in 2021 that requires over 2,400 public drinking water systems, also known as “Group A” systems, to test for PFAS. PFAS are a growing environmental contaminant of concern because some PFAS chemicals can be toxic to people and can build up in our bodies over time. PFAS are sometimes called "forever chemicals" in the news because they stay in the environment for a very long time. The Washington State Department of Health (DOH) collects drinking water test results for a large family of chemicals called per- and polyfluoroalkyl substances (PFAS).
