When your tap water doesn’t look, taste, or perform the way it should, you need answers—not guesswork.

Whether you’re served by Aqua Pennsylvania or rely on a private well, we understand the unique geology, infrastructure, and regulations that shape your water across Delaware and Montgomery counties—and we know exactly how to address them.

PFAS, Lead, and Emerging Contaminants

Delaware and Montgomery counties have well-documented histories of PFAS contamination, particularly near former military installations like Horsham and Warminster. While those areas faced the most severe exposure, Aqua Pennsylvania has taken wells offline throughout both counties due to elevated PFAS levels. Recent Penn State research found that approximately 18% of private wells in Pennsylvania contain detectable PFAS, with the highest concentrations in Southeastern Pennsylvania’s most developed areas.

Lead presents another serious concern for Ardmore’s many historic homes. This colorless, odorless contaminant enters tap water through corrosion of older plumbing materials, with homes built before 1986 at highest risk. The health stakes are significant—lead exposure can cause developmental issues in children and cardiovascular problems in adults. Professional water testing and targeted treatment solutions like reverse osmosis systems provide effective protection against these invisible threats. Learn more about water contaminants at our water chemistry guide.

Hard Water and Plumbing Corrosion

Delaware and Montgomery counties draw water from both surface sources and groundwater aquifers, resulting in variable mineral content. Many Ardmore residents experience moderate to high water hardness, which manifests as soap that won’t lather, cloudy dishes, dingy laundry, and that persistent bathtub ring. The real damage happens inside water heaters and pipes, where mineral scale reduces efficiency and shortens equipment lifespan. A professionally installed water softener addresses these challenges at the source.

Acidic water with pH below 7 can be highly corrosive to copper pipes and brass fixtures. Many private wells in the region produce water with pH levels between 5.5 and 6.5—low enough to cause blue-green stains, pinhole leaks, and metallic taste. An acid neutralizer system raises pH to safe levels, protecting your entire plumbing system. Pennsylvania’s groundwater chemistry makes pH testing critical for well owners, as detailed in our well water article.
