🧴 How Moreno Valley's Water Affects Your Skin, Hair & Health
When you shower, contaminants in the water don't just wash off — they're absorbed through your skin and inhaled as steam. Here's how Moreno Valley's water quality may be affecting you:
🧖 Skin Effects
- Dry, itchy skin and irritation
- Eczema flare-ups and redness
- Soap scum residue and poor lathering
- Potential for increased absorption of certain chemicals
💇 Hair Effects
- Dry, brittle, and dull hair
- Fading of hair color (especially dyed hair)
- Mineral buildup causing limpness and residue
- Difficulty rinsing shampoo and conditioner
🫁 Respiratory Effects
- Irritation of nasal passages and throat from chloramine vapor
- Exacerbation of asthma and allergies due to inhaled contaminants
- Potential for discomfort from volatile organic compounds (e.g., TTHMs) in steam
✅ What You Can Do About It
Test Your Water
Understanding your home's specific water profile is the first step. Home testing kits or professional labs can identify exact contaminant levels.
Install a Quality Shower Filter
A good shower filter can significantly reduce chlorine, chloramines, heavy metals, and other contaminants, protecting your skin and hair.
Adjust Shower Temperature
Using lukewarm water instead of very hot water can minimize steam inhalation of volatile chemicals and reduce skin dryness.
Moisturize Immediately After Showering
Applying moisturizer within minutes of getting out of the shower helps lock in hydration and counteracts drying effects from hard water or chemicals.
Limit Shower Duration
Shorter showers reduce your overall exposure time to contaminants in both the water and the steam.

Is Moreno Valley tap water safe to shower in?
While Moreno Valley's tap water meets federal drinking water standards, showering introduces unique exposure pathways. Contaminants like chloramines and hard minerals can impact skin and hair health, and volatile chemicals in steam can be inhaled, making informed choices beneficial.
What causes dry skin and hair after showering in Moreno Valley?
The primary culprits are hard water minerals (calcium and magnesium) and chloramines used for disinfection. Hard water leaves residue that dries skin and hair, while chloramines strip natural oils and can cause irritation, leading to dryness and dullness.
Do shower filters really make a difference for Moreno Valley water?
Yes, a high-quality shower filter can make a significant difference. Filters designed to reduce chloramines, heavy metals, and sediment can improve skin hydration, reduce hair damage, and alleviate respiratory irritation from steam.
How often should I replace my shower filter?
Most shower filters need to be replaced every 4 to 6 months, or after a certain gallon capacity, whichever comes first. Refer to your specific filter's instructions, as usage and local water quality can influence its lifespan.
Is the chlorine smell in my Moreno Valley shower water normal?
A slight chlorine-like smell is common and typically indicates the presence of chloramines, which EMWD uses for disinfection. While normal, this odor signifies the very chemicals that can contribute to skin and hair issues and respiratory irritation.
