What are the impacts of PFAS?
- There are many health risks associated with exposure to PFAS, even when ingested at very low levels. Specifically, these chemicals are associated with increased risk of cancers, thyroid disease, ulcerative colitis, pregnancy-induced hypertension, Type-2 diabetes in women, pre-eclampsia, developmental delays in children, increased risks of low birth weights, decreased antibodies in children, hypothyroidism and increase thyroid disease, immunosuppression, infertility, increased cholesterol, liver function disruptions, thyroid and hormone level changes, developmental effects, decreased antibody response, memory impairment, and other health conditions.
If my water is contaminated, will bathing in it, washing my hands with it, etc. put me at risk?
- Because PFAS are not readily absorbed through the skin, contacting water containing PFAS while showering and bathing is not a health concern. However, small amounts of water may be ingested while showering and bathing. If PFAS has been identified in your water at concentrations substantially greater than the MCL, avoid swallowing water while showering or bathing and monitor young children to limit the amount of water they swallow.
- If your skin has cuts, abrasions, open sores, or other wounds, you may want to limit the amount of time spent showering, bathing or soaking in water with PFAS levels greater than the MCL.
Is it OK to clean wounds or sores with PFAS-contaminated water?
- PFAS in water are not easily absorbed through the skin. If you have a rash, cuts, or broken skin on your hands, you can minimize any absorption by wearing rubber gloves when washing dishes. It is our understanding that dishes that have been washed with water containing PFAS do not pose a health risk.
Is it OK to eat fruits and vegetables from my garden if my soil, compost, or irrigation water is contaminated with PFAS?
- It is possible for plants to take up PFAS from external sources (e.g. water, soil, compost). Although PFAS do not stick to soil very well, gardens watered with PFAS-contaminated water or enriched with PFAS containing compost may have somewhat higher levels of PFAS in the soil. The amount of PFAS in home-grown plants depends on levels in the water, soil and compost as well as the type of plant, nutrient levels in soil, and the specific PFAS. At this time, it is not possible to predict what the PFAS concentration would be in plants grown in an environment containing PFAS.
- To reduce the potential exposure to PFAS in home-grown produce, you can:
- Water seeding and gardens with an alternative source of water, such as collected rain water.
- If using compost, note that PFAS concentrations in biosolid compost may contain higher levels of PFAS than other types of compost (such as backyard compost or manure). If you are unsure whether the compost you select contain PFAS, contact the manufacturer.
- Wash all fruits, vegetables and herbs in clean water before eating.
- Peel root vegetables before eating.
- Use a raised bed filled with clean soil or add clean soil to existing beds.
Is it safe to clean things like dentures or pacifiers with water found to have levels of PFAS above the MCL?
- Even though only a small amount of water might be swallowed and the risk of experiencing adverse health effects is very low, you can minimize any risk by not using water with PFAS greater than the MCL to wash items that might go directly in your mouth. If PFAS levels in your drinking water are substantially greater than the MCL, you may wish to use PFAS-tested bottled or filter water for:
- Brushing your teeth
- Cleaning dentures
- Cleaning baby bottles, nipples, pacifiers and teething toys
I’m sick now – what do I do?
- If you are feeling ill or experiencing symptoms, you should seek treatment immediately with a medical provider. We encourage everyone to document anything relating to their health and subsequent medical treatment. In addition to medical records, this can include a journal or other document of symptoms and dates.
- If you are not experiencing symptoms and have not sought regular medical care based on the recommendations for your age group, we recommend that you do so.
Is there a particular type of blood test to assess my exposure?
- Yes, there is a blood test specific for PFAS chemicals. If you wish to get a blood test, we recommend that you speak with your primary care provider. If you have water test results demonstrating your drinking water has been contaminated, providing those to your health care provider can sometimes assist the health care provider in ordering the appropriate test.
My pet or companion animal has been drinking PFAS-contaminated water, will they get sick?
- Because companion animals and pets are different sizes, have different lifespans, and drink different amounts of water than people, it’s not possible to predict what health effects an animal may experience from drinking water with PFAS concentrations greater than the MCL. To be on the safe side, give pets clean drinking water when possible. If you have concerns, you may want to consult with your veterinarian.
