- Color fading and brassiness in treated hair.
- Residue buildup, making hair feel heavy and less manageable.
- Scalp irritation and increased dandruff.
🫁 Respiratory Effects
- Inhalation of chloramine and disinfection byproducts (DBPs) in steam.
- Triggering or worsening of asthma and allergy symptoms.
- Sinus irritation, coughing, and general respiratory discomfort.
- Potential long-term respiratory health concerns from chronic DBP exposure.
✅ What You Can Do About It
Test Your Shower Water
A home water test kit can identify specific contaminant levels in your shower water, giving you a clear picture of what you're being exposed to.
Install a Quality Shower Filter
A good shower filter can significantly reduce chlorine, chloramine, heavy metals, and other contaminants, improving water quality for your skin and hair.
Improve Bathroom Ventilation
Running an exhaust fan or opening a window during and after showering helps reduce the concentration of airborne chemicals like DBPs in steam.
Limit Shower Duration and Temperature
Shorter, cooler showers reduce the amount of time your skin is exposed to contaminants and minimize the vaporization of harmful chemicals.
Moisturize Immediately After Showering
Applying a rich moisturizer to damp skin within minutes of showering helps lock in hydration and creates a protective barrier against dryness.

Is Eugene tap water safe to shower in?
Eugene's tap water meets all EPA safety standards for drinking, making it generally safe for showering. However, contaminants like chloramine and disinfection byproducts, while within legal limits, can still cause issues like dry skin, hair damage, and respiratory irritation, especially for sensitive individuals.
Does Eugene water cause dry skin or hair damage?
Yes, for many people, Eugene's water can contribute to dry skin and hair damage. The chloramine used for disinfection can strip natural oils, leading to dryness and irritation. While Eugene's water is naturally soft, the presence of other chemicals can still impact skin and hair health.
Why does my shower water in Eugene sometimes smell like chlorine?
The chlorine smell in your shower water comes from chloramine, the disinfectant used by Eugene Water & Electric Board (EWEB). While effective at killing bacteria, chloramine can off-gas, especially in hot shower water, creating a noticeable odor and contributing to respiratory irritation.
Can Eugene's shower water worsen eczema?
Yes, the chemicals present in Eugene's shower water, particularly chloramine and disinfection byproducts, can irritate sensitive skin and exacerbate eczema symptoms. These chemicals can strip the skin's natural barrier, leading to increased dryness, itching, and flare-ups for eczema sufferers.
Are shower filters effective for Eugene's water?
Absolutely. Shower filters are highly effective at reducing common contaminants found in Eugene's water, such as chloramine, chlorine, and some heavy metals. This can lead to noticeable improvements in skin hydration, hair softness, and a reduction in respiratory irritation from chemical vapors.
