- Minor risk from radon gas inhalation from naturally occurring radionuclides
✅ What You Can Do About It
Test Your Home's Water
A professional water test can provide precise data on contaminants and hardness levels specific to your home, offering the clearest picture of your water quality.
Install a Quality Shower Filter
Shower filters are effective at reducing chlorine, chloramine, and some disinfection byproducts, which can significantly improve skin and hair health and reduce respiratory irritation.
Limit Shower Time and Temperature
Shorter, cooler showers reduce exposure to volatile chemicals like chloramine and DBPs, and help prevent excessive drying of skin and hair.
Moisturize Immediately After Showering
Applying a rich moisturizer to damp skin within minutes of showering helps lock in hydration and creates a barrier against environmental irritants.
Consider a Whole-House Water Filter or Softener
For comprehensive protection against contaminants and hard water throughout your home, a whole-house system provides benefits beyond just the shower.

Is Port St. Lucie tap water safe to shower in?
While Port St. Lucie's tap water meets federal drinking water safety standards, meaning it's generally safe for showering, it contains elements like chloramine and hard water minerals that can negatively impact skin, hair, and respiratory comfort. For individuals with sensitivities or specific health concerns, addressing these issues can significantly improve your showering experience.
Why does my skin feel dry and itchy after showering in Port St. Lucie?
The primary culprits are likely chloramine, used for disinfection, and the high mineral content (hardness) in Port St. Lucie's water. Chloramine strips natural oils from your skin, while hard water leaves a residue that can clog pores and exacerbate dryness and itchiness, especially for those with conditions like eczema.
Does Port St. Lucie's hard water damage hair?
Yes, hard water in Port St. Lucie can indeed damage hair. The high levels of calcium and magnesium minerals can build up on hair strands, leading to dullness, frizz, breakage, and even affecting the vibrancy of colored hair. It also makes it harder for shampoos to lather effectively, potentially leading to more product use and residue.
Can a shower filter really make a difference for my skin and hair in Port St. Lucie?
Absolutely. A quality shower filter is designed to reduce common irritants like chloramine and some disinfection byproducts, which are major contributors to dry skin, irritated scalps, and damaged hair. Many users in hard water areas like Port St. Lucie report noticeable improvements in skin hydration, hair softness, and reduced itching after installing a filter.
What are disinfection byproducts and why are they in my shower water?
Disinfection byproducts (DBPs) like Haloacetic Acids (HAA5) and Total Trihalomethanes (TTHMs) are formed when disinfectants like chloramine react with naturally occurring organic matter in the water. They are present in shower water because they are a result of the necessary disinfection process, and they can become airborne in shower steam, leading to inhalation and skin absorption.
