✅ What You Can Do About It
Test Your Home's Water
A home water test kit can provide specific data on contaminants present in your tap water, allowing for targeted solutions.
Install a Quality Shower Filter
Shower filters effectively reduce chlorine, chloramine, heavy metals, and some DBPs, improving skin and hair health while reducing respiratory irritation.
Consider a Whole-House Filtration System
For comprehensive protection against a wider range of contaminants throughout your entire home, a whole-house system is a more robust solution.
Use pH-Balanced Skincare Products
Counteract the drying effects of hard water and chlorine by using moisturizers and cleansers that help restore your skin's natural barrier.
Limit Shower Time and Temperature
Shorter, cooler showers can reduce exposure to volatile contaminants like TTHMs and minimize the stripping of natural skin oils.

Is Harrisburg tap water safe to shower in?
While Harrisburg's tap water meets federal drinking water standards, showering exposes you to contaminants differently. Volatile chemicals like chlorine and disinfection byproducts can be inhaled in steam and absorbed through the skin, potentially leading to skin, hair, and respiratory issues.
What are disinfection byproducts (DBPs) and why are they in my shower water?
DBPs like TTHMs and HAA5s form when disinfectants, primarily chlorine, react with naturally occurring organic matter in the water. They are a concern in showers because they easily vaporize in hot water, leading to inhalation exposure and skin absorption.
Does Harrisburg have hard water?
Yes, Harrisburg's water is generally considered moderately hard. This means it contains higher levels of minerals like calcium and magnesium, which can lead to dry skin, dull hair, and soap scum buildup in your shower.
How effective are shower filters for Harrisburg water?
Shower filters can be very effective at reducing specific contaminants like chlorine, chloramines, and some heavy metals, significantly improving the quality of your shower experience. Look for filters certified to remove the specific contaminants of concern in Harrisburg's water.
Can showering in Harrisburg water worsen my eczema?
Yes, the chlorine and hardness minerals in Harrisburg's shower water can strip natural oils from your skin, disrupt its protective barrier, and exacerbate dry, itchy skin conditions like eczema. Using a shower filter and moisturizing immediately after showering can help mitigate these effects.
