PFAS in Seattle & Washington water

PFAS — often called “forever chemicals” — have become one of the most talked-about water quality issues in the country. Here's the short version: what they are, whether they're likely in your water, and what actually removes them.

What are PFAS?

PFAS are a large family of man-made chemicals used for decades in things like non-stick coatings, water-repellent fabrics, and firefighting foam. They're nicknamed “forever chemicals” because they don't easily break down — so once they reach groundwater, they tend to stick around.

Are PFAS in my water?

It depends entirely on where your water comes from. Some Pacific Northwest source water is naturally very low in PFAS, while other areas — particularly near industrial sites and military bases — have measurable contamination. Regional averages can't answer the question for your home. The only way to know is to test the water at your own tap.

How do you remove PFAS from water?

The good news: PFAS are filterable. Reverse osmosis is one of the most effective and widely recommended ways to reduce PFAS in drinking water, which is why every system we install includes RO at the kitchen tap. If your test comes back clean, you'll know that too — and you won't have paid for filtration you don't need.

The bottom line

PFAS are worth taking seriously, but they're not a reason to panic. Test first, see your actual numbers, and filter based on what's really there. That's the whole idea behind how we work.
