Spring Water Quality Check in Ardmore, PA: What Montco & Delco Homeowners Should Know About Their Tap Water This May

Ardmore runs on public water supplied through the Aqua Pennsylvania system, not private wells. But public water doesn’t mean perfectly pure water — and spring is a season when a lot of homeowners in Ardmore, Haverford Township, and the surrounding Lower Merion area start noticing things about their tap water they hadn’t noticed before. Sediment, taste changes, dry skin after showering, and scale buildup on fixtures are all signs that your water may have room for improvement. May is a smart time to take a closer look.

Why Spring Matters for Ardmore Tap Water

Your water utility does the work of meeting federal and state standards before it reaches your meter. That’s a meaningful baseline — but it doesn’t tell the whole story about what comes out of your tap. Spring brings increased runoff into source water reservoirs, higher treatment chemical demands, and seasonal variation in what municipal systems deliver. And once water enters your home’s plumbing, the utility’s job is done. What happens after that is up to your pipes, fixtures, and any treatment equipment you have in place.

Aqua Pennsylvania serves much of Haverford Township, Lower Merion, and surrounding Montgomery and Delaware County communities. Their annual water quality report shows what’s in the treated supply — but it also shows contaminants that are detected at or near the action level, including regulated substances that have raised questions among homeowners in the area.

Water Quality Concerns Specific to Ardmore and Haverford Township

Hard Water Throughout the Main Line

The limestone-dominated geology of Montgomery and Delaware counties means hard water is common throughout the Main Line corridor, including Ardmore, Havertown, Bryn Mawr, and Narberth. Hard water causes scale buildup inside water heaters, shortens appliance life, leaves spots on dishes and glass, and is often what’s behind dry skin and dull hair after showering. A water softener addresses this directly and makes a noticeable difference quickly.

Chlorine and Chloramine in Treated Water

Public water systems use chlorine or chloramine to disinfect treated water. This is necessary for safety in the distribution system, but it also means the water reaching your tap contains these compounds at detectable levels. Some homeowners are sensitive to the taste or smell. Others are more concerned about the longer-term effects of chlorine and chloramine exposure. A whole-home carbon filter or an under-sink system can address this at the point of use.

PFAS in the Regional Water Supply

PFAS have been detected in public water systems across the Philadelphia suburbs, including in systems serving parts of Montgomery and Delaware counties. The EPA’s updated PFAS standards set lower maximum contaminant levels than previously required, and some utilities are still in the process of compliance. Understanding what’s in your water — and whether a point-of-use reverse osmosis system makes sense for your drinking water — is a reasonable step for any Ardmore homeowner right now.

Older Plumbing and Internal Pipe Concerns

Ardmore has a lot of older housing stock — homes built in the early to mid-1900s where internal plumbing hasn’t always been updated. Older solder joints and fixtures can leach lead and copper into water at the tap, even when utility-delivered water tests clean. If your home was built before 1986, this is worth knowing about. Learn more about treating lead in your water and what your options are.

What Public Treatment Doesn’t Address Inside Your Home

There’s a clear gap between what your water utility delivers and what comes out of your tap. Hardness minerals are not removed by standard municipal treatment — they’re naturally present and legally allowed. Treatment chemicals like chlorine and chloramine travel all the way to your faucet by design. And anything that happens inside your home’s plumbing — leaching from old pipes, sediment accumulation — happens after the utility’s responsibility ends.
