Are there ways to reduce exposure to PFAS?

Drinking contaminated water is the most common PFAS exposure pathway.


That's why it's so important to test municipal water supplies to make sure PFAS chemicals aren't present. Use an alternate water source for drinking, preparing food, cooking, and brushing teeth if drinking water is contaminated above safe health levels.

Other steps you can take to protect yourself and your family include the following:

Stain-resistant carpets
Stain-resistant carpets are a significant exposure pathway for infants and young children. Choose carpets that aren’t marketed as “stain-resistant,” and don’t apply finishing treatments such as Stainmaster to them.


Non-stick coatings

Instead of non-stick cookware, opt for ceramic, stainless steel, or cast iron. If the coating on your non-stick cookware begins to peel, do not use it.

Waterproof fabrics and waterproofing sprays

Avoid using optional waterproofing sprays on clothing and footwear. Look for raincoats and other outdoor gear labeled PFAS-free or fluoro-free. These products will be increasingly available in as little as two or three years.

Food packaging

Eat more fresh foods to avoid take-out containers and other food packaging like french fry cartons, pizza boxes, and microwave popcorn bags.


Cosmetics and personal care products

Read the ingredient list on cosmetics and personal care products, including dental floss. Look for words beginning with “fluoro-”, “perfluoro-”, or “polyfluoro-”. Do not purchase products containing these ingredients. Look for dental floss that is uncoated or coated in natural wax.

Fish and wild game

Fish and deer can take in pollutants from the environment. Reduce potential health risks from PFAS by following Wisconsin's guidelines for fish consumption and guidelines for wild game consumption.
