- Exacerbation of eczema, psoriasis, and other skin sensitivities.
- Residue buildup, leading to dullness and clogged pores.
- Potential for premature skin aging from oxidant exposure.
💇 Hair Effects
- Dry, brittle, and frizzy hair from mineral buildup and chloramine.
- Fading of hair color and chemical treatments.
- Reduced lathering of shampoos and conditioners, making hair feel unclean.
- Scalp irritation and increased dandruff due to mineral deposits.
🫁 Respiratory Effects
- Inhalation of chloramine and disinfection byproducts (TTHMs, HAA5s) via steam.
- Potential for respiratory irritation, especially in individuals with asthma or allergies.
- Increased risk of exposure to volatile organic compounds (VOCs) that off-gas from hot water.
- Long-term inhalation of DBPs linked to respiratory issues.
✅ What You Can Do About It
Test Your Home's Water
A comprehensive home water test can provide precise data on contaminants specific to your plumbing, offering a clear picture of your shower water quality.
Install a Quality Shower Filter

Is Spring Valley tap water safe to shower in?
While Spring Valley's tap water meets federal drinking water standards, showering introduces unique exposure routes like steam inhalation and skin absorption. Contaminants like chloramine and disinfection byproducts can pose concerns for sensitive individuals or those seeking optimal skin and hair health.
Why does my Spring Valley shower water smell like chlorine?
The chlorine smell in your Spring Valley shower water is primarily due to chloramine, which the Southern Nevada Water Authority uses as a disinfectant. While effective at killing harmful bacteria, chloramine can off-gas in hot water, creating a noticeable odor and potentially irritating sensitive individuals.
How does Spring Valley's hard water affect my skin and hair?
Spring Valley's moderately hard water, rich in minerals like calcium and magnesium, can leave a residue on your skin and hair. This residue can lead to dryness, itchiness, dull hair, and can exacerbate conditions like eczema by preventing moisturizers from fully penetrating.
Are shower filters effective for Spring Valley water?
Yes, shower filters can be highly effective for Spring Valley water, especially those designed to remove chloramine, chlorine, heavy metals, and sediment. They can significantly reduce exposure to these contaminants, leading to softer skin, healthier hair, and less respiratory irritation.
Will Spring Valley water cause my hair color to fade faster?
Yes, the combination of chloramine and hard water minerals in Spring Valley's water can accelerate hair color fading. Chloramine is an oxidant that breaks down dye molecules, while mineral buildup can make hair appear dull and prevent color from adhering properly.
