✅ What You Can Do About It
Test Your Water
A professional water test can reveal specific contaminant levels in your home, providing a precise understanding of your water quality beyond city reports.
Install a Shower Filter
A high-quality shower filter can significantly reduce chlorine, chloramine, TTHMs, and hardness minerals, improving skin and hair health.
Reduce Shower Time and Temperature
Shorter, cooler showers minimize exposure to volatile chemicals like chloramine and TTHMs, and reduce the drying effects of hot water on skin and hair.
Use Moisturizing Products
Opt for sulfate-free shampoos, conditioners, and rich moisturizers to counteract the drying effects of hard water and disinfectants.
Consider a Whole-House Filter
For comprehensive protection against a wider range of contaminants throughout your home, a whole-house filtration system can be a long-term solution.

Is Jacksonville tap water safe to shower in?
While Jacksonville's tap water meets federal drinking standards, showering exposes you to contaminants differently. Inhaling steam and absorbing chemicals through your skin can have specific health and aesthetic impacts not fully addressed by drinking water regulations.
Why does my shower water in Jacksonville smell like chlorine?
Jacksonville uses chloramine, a disinfectant, to keep water safe from bacteria. This chemical can volatilize in hot shower water, creating a noticeable chemical odor that many people associate with chlorine.
Does hard water in Jacksonville affect my skin and hair?
Yes, Jacksonville's water is moderately hard. The high mineral content can leave residue on your skin and hair, leading to dryness, irritation, dullness, and difficulty in rinsing off soap and shampoo effectively, often exacerbating conditions like eczema.
Can a shower filter really make a difference?
Absolutely. A quality shower filter is designed to reduce common shower contaminants like chloramine, TTHMs, and sometimes even heavy metals and hardness minerals. This can lead to noticeable improvements in skin hydration, hair softness, and a reduction in chemical odors.
Are there specific concerns about the Floridan Aquifer water?
Water from the Floridan Aquifer can naturally contain dissolved minerals causing hardness, and in some areas, naturally occurring contaminants like arsenic and radon. While treated, these elements are considerations for overall water quality in Jacksonville.
