✅ What You Can Do About It
Test Your Home's Water
A professional water test can identify specific contaminants and their levels, providing a clear picture of what's in your Charleston shower water.
Install a Quality Shower Filter
A good shower filter can reduce chlorine/chloramine, heavy metals, and other contaminants, leading to softer skin and healthier hair.
Limit Shower Time and Temperature
Shorter, cooler showers reduce exposure to contaminants through steam inhalation and minimize the stripping of natural skin oils.
Moisturize Immediately After Showering
Applying a moisturizer to damp skin helps lock in hydration, counteracting the drying effects of hard water and chlorine.

Is Charleston tap water safe to shower in?
While Charleston's tap water meets EPA drinking water standards, showering exposes you to contaminants differently. Hot water can vaporize chemicals like chloramine and disinfection byproducts, leading to inhalation and skin absorption, which may pose concerns for sensitive individuals.
Why does my skin feel dry and itchy after showering in Charleston?
Charleston's water contains chloramine, which can strip natural oils from your skin, and it's also moderately hard. The minerals in hard water, along with chloramine, can leave a residue that irritates and dries out your skin, especially for those with eczema.
Do shower filters really work for Charleston water?
Yes, a high-quality shower filter can be very effective in Charleston. Filters designed to reduce chloramine, heavy metals, and sediment can significantly improve your shower experience, leading to softer skin, healthier hair, and reduced irritation.
What are Disinfection Byproducts (DBPs) and why are they in my shower water?
DBPs like Haloacetic Acids and Trihalomethanes form when disinfectants like chloramine react with organic matter in the water. These compounds can become airborne in shower steam and be inhaled, posing potential long-term health risks with chronic exposure.
How does hard water in Charleston affect my hair?
Hard water minerals, like calcium and magnesium, can build up on your hair strands, making them feel dry, dull, and brittle. This mineral residue can also prevent shampoos from lathering effectively and may cause hair color to fade faster.
