Serving Southern Chester County with Trusted, Local Water & Plumbing Solutions
For homeowners in zip code 19348, water quality in Kennett Square often starts with concerns about hard water, and extends to chlorine taste, PFAS, and aging infrastructure. Whether you rely on local groundwater wells or the municipal supply through Kennett Square Municipal Water Works, you deserve clarity—and control—over your home’s water.
According to the most recent Kennett Square Consumer Confidence Report, the borough’s municipal water system meets EPA standards—but reports from EWG show that several disinfection byproducts (TTHMs, bromodichloromethane, chloroform) exceed health-based guidelines (Penn State, kennettsq.org, EWG). Plus, Penn State research indicates approximately 18% of PA private wells have PFAS above federal limits—especially in Southeastern counties like Chester (WHYY).
If you’re noticing scale, dry skin, or strange odors, the best step is a professional water test. We make it simple with expert service and responsive reporting.
