- Chloramine can strip natural oils, potentially leading to premature aging
- Potential allergic reactions or rashes from contaminants like hexavalent chromium
💇 Hair Effects
- Increased dryness and brittleness, leading to breakage and split ends
- Fading of hair color, especially dyed hair, due to oxidizing agents like chloramine
- Buildup of mineral and chemical residues causing dullness and frizz
- Scalp irritation and flakiness due to chemical exposure
🫁 Respiratory Effects
- Inhalation of chloramine and disinfection byproducts can irritate airways and lungs

✅ What You Can Do About It
Test Your Home's Water
Understanding the specific contaminants in your home's water is the first step. Professional testing can reveal levels of lead, copper, and disinfection byproducts that may vary by household due to plumbing.
Install a Quality Shower Filter
A good shower filter can significantly reduce chlorine, chloramine, heavy metals, and disinfection byproducts, leading to noticeable improvements in skin and hair health.
Shorten Shower Times and Lower Temperature
Reducing the duration and heat of your showers minimizes the amount of time you're exposed to chemical vapors and reduces the skin's absorption rate of contaminants.
Moisturize Immediately After Showering
Applying a high-quality moisturizer to damp skin helps to lock in moisture and counteract the drying effects of chlorinated water, especially beneficial for eczema sufferers.
Consider a Whole-House Filtration System
For comprehensive protection against contaminants throughout your entire home, a whole-house filtration system offers superior water quality for all uses, including bathing and drinking.

Is Hartford tap water safe to shower in?
While Hartford's tap water meets federal drinking water standards, showering introduces unique exposure pathways. Contaminants like chloramine and disinfection byproducts can be inhaled as steam or absorbed through the skin, potentially causing irritation or long-term health concerns, even if levels are deemed 'safe' for ingestion.
What causes dry skin and hair after showering in Hartford?
The primary culprits are chloramine, which strips natural oils from skin and hair, and potentially trace minerals that can build up. Disinfection byproducts can also contribute to skin sensitivity and dryness, leading to issues like eczema flare-ups and brittle hair.
Does Hartford have hard water?
No, Hartford's water, supplied by the MDC, is generally considered soft to moderately soft. This means mineral buildup (like calcium and magnesium) on fixtures is less of a concern compared to areas with very hard water, but other chemical contaminants still affect skin and hair.
How effective are shower filters for Hartford water?
Shower filters can be highly effective at reducing common Hartford water contaminants, particularly chloramine and its byproducts, which are major irritants. They work by using filtration media to neutralize or capture these chemicals, leading to softer skin, shinier hair, and reduced respiratory exposure.
What are disinfection byproducts (DBPs) and why are they in my shower water?
Disinfection byproducts (DBPs) like TTHMs and HAA5s form when disinfectants, such as chloramine used in Hartford, react with naturally occurring organic matter in the water. They are concerning because they can become airborne in hot shower steam and be inhaled, posing health risks beyond just ingestion.
