Analysis

What to know about Fairchild Afb's water

Fairchild Afb ranks #119 out of 294 cities in Washington for water quality, placing it mid-range in the state.

Fairchild Afb relies on groundwater, which is generally less vulnerable to surface contamination but can be affected by naturally occurring minerals like arsenic and nitrate, as well as agricultural and industrial runoff.

Of particular concern: PFAS "forever chemical" levels exceed the 2024 EPA maximum contaminant levels. These synthetic compounds don't break down naturally and require specialized filtration such as reverse osmosis or granular activated carbon.

Where does Fairchild Afb's water come from?

Fairchild Afb's drinking water comes from groundwater (wells), supplied by 1 water system serving approximately 5,553 people. Groundwater is generally less susceptible to surface contamination but can contain naturally occurring contaminants like arsenic, radon, and nitrate.

What Fairchild Afb residents can do

Install a water filter

Recommended: Reverse osmosis system. This addresses the specific contaminants found in Fairchild Afb's water.

Request your utility's CCR

Your water utility is required to publish an annual Consumer Confidence Report (CCR) with detailed testing results. Ask for the latest copy or check your utility's website.

Flush your taps

Run cold water for 30 seconds before drinking, especially in the morning. Lead and copper leach from household plumbing when water sits in pipes.

Where Fairchild Afb's water comes from

Groundwater

Fairchild Afb's drinking water is drawn from underground aquifers through wells.

Groundwater is naturally filtered through rock and soil layers, generally requiring less treatment than surface water. However, it can contain naturally occurring contaminants like arsenic, radon, and minerals.

Agricultural activity, septic systems, and industrial operations near well fields can introduce nitrates, pesticides, and volatile organic compounds.

The system is operated by federal ownership and serves approximately 5,553 people through 1 water system.
