🚿 Alaska Shower Water Quality Report (2026)
Comprehensive analysis of Alaska water quality across 2 cities • Based on real EWG testing data • Updated 2026
If you live in Alaska, you may be showering in water that contains contaminants exceeding health guidelines — and you might not even know it. Our analysis of water quality data across 2 Alaska cities reveals 8 contaminants that may exceed EWG health guidelines.
Alaska faces unique water quality challenges including remote water systems and naturally occurring minerals. Whether you're in Juneau or elsewhere in the state, understanding what's in your shower water is the first step toward protecting your skin and hair.
📊 Alaska Water Quality at a Glance
Across Alaska, we analyzed water quality data from the Environmental Working Group (EWG) database. The results show that Alaska residents may be exposed to a range of contaminants through their shower water — many at levels that exceed health guidelines set by the EWG, which are often stricter than federal legal limits.
⚠️ Top Contaminants Found in Alaska Water
Based on EWG data analysis, here are the most significant contaminants detected in Alaska water supplies:
| Contaminant | Avg. Level | EWG Guideline | Status |
|---|---|---|---|
| Perfluorohexane sulfonate (PFHXS) | 0.0000 ppt | 0.0000 ppt | ⚠️ 1004.0x above |
| Haloacetic acids (HAA9) | 6.64 ppb | 0.0600 ppb | ⚠️ 110.7x above |
| Haloacetic acids (HAA5) | 10.13 ppb | 0.1000 ppb | ⚠️ 101.3x above |
| Total trihalomethanes (TTHMs) | 10.37 ppb | 0.1500 ppb | ⚠️ 69.2x above |
| Trichloroacetic acid | 5.29 ppb | 0.1000 ppb | ⚠️ 52.9x above |
| Nitrate and nitrite | 6.1180 ppm | 0.1400 ppm | ⚠️ 43.7x above |
| Chloroform | 9.75 ppb | 0.4000 ppb | ⚠️ 24.4x above |
| Dichloroacetic acid | 4.69 ppb | 0.2000 ppb | ⚠️ 23.5x above |
Perfluorohexane sulfonate (PFHXS)
The health guideline of 0.001 ppt for perfluorohexane sulfonate was defined by EWG based on studies by Phillipe Grandjean of Harvard University and many other independent researchers who found reduced effectiveness of vaccines and adverse impacts on mammary gland development from exposure to PFOA and PFOS, the two PFAS most widely detected in drinking water. This health guideline harm to the developing immune system.
National Average: 0.0000 ppt | Alaska Average: 0.0000 ppt
Haloacetic acids (HAA9)
The health guideline of 0.06 ppb for haloacetic acids (HAA9) was defined by EWG . This health guideline protects against cancer.
National Average: 23.70 ppb | Alaska Average: 6.64 ppb
Haloacetic acids (HAA5)
The health guideline of 0.1 ppb for haloacetic acids (HAA5) was established. This health guideline protects against cancer.
National Average: 19.82 ppb | Alaska Average: 10.13 ppb
Total trihalomethanes (TTHMs)
The health guideline of 0.15 ppb for trihalomethanes was defined by in a peer-reviewed scientific study by EWG and represents a one-in-one-million lifetime cancer risk level. as a draft public health goal, the level of drinking water contaminant that does not pose a significant health risk. This health guideline protects against cancer.
National Average: 29.06 ppb | Alaska Average: 10.37 ppb

🩺 Health Effects of Alaska Water Contaminants
The contaminants found in Alaska water may be associated with various health concerns. When you shower, your skin — your body's largest organ — can absorb these substances, and you may inhale steam containing volatile compounds.
🧴 Skin & Hair
🫁 Respiratory
- Steam inhalation of chlorine/VOCs
- May aggravate asthma symptoms
- Potential respiratory irritation
⚕️ Long-Term Concerns
- Disinfection byproduct exposure
- Eczema flare-ups
- Cumulative contaminant absorption
🛡️ How to Protect Yourself from Alaska Water Contaminants
The good news: you don't have to accept whatever comes out of your Alaska showerhead. A quality shower filter can significantly reduce many of the contaminants found in your water.
Key contaminants a shower filter can help address:
- Haloacetic acids (HAA9) — learn about health effects and removal
- Total trihalomethanes (TTHMs) — learn about health effects and removal
- Nitrate and nitrite — learn about health effects and removal
- Chlorine — learn about health effects and removal
Additionally, understanding common symptoms can help you identify water quality issues:

Is Alaska tap water safe to shower in?
While Alaska tap water meets federal legal standards (MCLs), our analysis found 8 contaminants exceeding stricter EWG health guidelines. Federal limits don't always reflect the latest health research, so many health-conscious residents choose to add shower filtration for an extra layer of protection.
What contaminants are in Alaska water?
Based on EWG data, Alaska water contains up to 28 detected contaminants. The most notable include Perfluorohexane sulfonate (PFHXS), Haloacetic acids (HAA9), Haloacetic acids (HAA5). Alaska faces specific challenges with remote water systems and naturally occurring minerals.
Does Alaska have hard water?
Alaska water tends to be on the softer side, though mineral levels can vary by municipality. Even soft water may contain other contaminants of concern.
Do I need a shower filter in Alaska?
Given that Alaska water contains contaminants above EWG health guidelines, a shower filter may help reduce your exposure to chlorine, heavy metals, and disinfection byproducts. This is especially important if you experience dry skin, itchy scalp, or hair issues after showering.
How does Alaska water compare to the national average?
Alaska is in the Pacific Northwest region and faces water quality challenges common to the area, including remote water systems and naturally occurring minerals. Some contaminants may be above national averages depending on your specific city and water source.
