Quick answers: West Chester, PA water quality
Is West Chester, PA’s water safe to drink?
West Chester’s public water, supplied by Aqua Pennsylvania, meets all federal and state drinking water standards. But “meeting regulations” isn’t the same as ideal for every home. PFAS, older home plumbing, chlorine taste, and hard water can all affect what actually reaches your tap, so an in-home water test is the only way to know what’s in your specific water.
Where does West Chester’s drinking water come from?
Most West Chester Borough homes are served by Aqua Pennsylvania, which draws from Brandywine Creek and several groundwater wells, then treats and disinfects the water before distributing it throughout the community.
Does West Chester’s water contain PFAS?
Testing by Aqua Pennsylvania has detected several PFAS (“forever chemicals”) compounds in the West Chester system. Federal limits for PFOA and PFOS remain at 4 parts per trillion, and point-of-use filtration can significantly reduce many PFAS compounds in your drinking water. A home water test tells you which compounds are present at your tap.
Why does my West Chester tap water smell like chlorine?
Municipal systems keep a small amount of chlorine in the water to stop bacteria from growing as it travels through miles of underground pipe. It’s a normal public health measure, but a whole-home or drinking-water filter can remove the taste and odor.
Do I need a water softener or a filter in West Chester?
It depends on your water. Hard water (calcium and magnesium) is treated with a softener; chlorine taste and PFAS are addressed with carbon or point-of-use filtration; dirt and rust need a sediment filter. Because no single system solves everything, Mattioni starts with professional water testing before recommending equipment for Chester County homes.

Have you ever wondered what’s actually coming out of your tap when you fill a glass of water? Or maybe you’ve noticed spots on your dishes, dry skin after showering, or a chlorine taste and started asking yourself whether your water is as clean as it should be.
At Mattioni, we’ve spent over 75 years helping homeowners throughout Chester County understand (and improve) their water quality. While West Chester’s municipal water consistently meets federal and state drinking water standards, there’s much more to water quality than simply meeting regulations. Every home’s plumbing system, water source, and treatment needs are different.
In this article, we’ll explain where West Chester’s water comes from, discuss the latest concerns surrounding PFAS (Polyfluoroalkyl Substances, aka “forever chemicals”), lead, chlorine, and hard water, and help you understand when a water conditioning system may be the right investment for your home.

Where Does West Chester’s Drinking Water Come From?
Most West Chester Borough homes receive water supplied by Aqua Pennsylvania. The system draws water from both Brandywine Creek and several groundwater wells before treating it and distributing it throughout the community. Using both surface water and groundwater helps provide a reliable supply throughout the year while reducing dependence on any single source.
Before reaching your home, this water undergoes multiple treatment processes designed to remove sediment, microorganisms, and other contaminants while maintaining a disinfectant residual throughout the distribution system. According to Aqua Pennsylvania’s most recent Consumer Confidence Report, the West Chester system met all applicable drinking water regulations during the latest reporting period.
However, many homeowners are surprised to learn that “meeting regulations” doesn’t necessarily mean every substance has been eliminated. Modern lab testing can detect contaminants at incredibly small concentrations (often measured in parts per trillion), and researchers continue learning more about how long-term exposure to certain chemicals may affect human health.
PFAS: The Water Quality Issue Everyone Is Talking About
One of the biggest water quality discussions across the country involves PFAS, commonly called “forever chemicals.”
PFAS are a family of man-made chemicals that have been used for decades in nonstick cookware, food packaging, and many industrial products. Because they break down extremely slowly, they can remain in groundwater and rivers for many years.
Testing performed by Aqua Pennsylvania detected several PFAS compounds in the West Chester water system. While these results complied with regulations for the reporting period (2024), the EPA now operates under stricter drinking water standards. The West Chester public water system is now evaluating treatment upgrades where necessary to meet the new federal standards.
For homeowners who want additional peace of mind about forever chemicals, point-of-use filtration systems can significantly reduce several PFAS compounds in drinking water. Choosing the right solution, however, depends on your home’s specific water quality, making an in-home water test essential.
Lead Usually Isn’t in Your Water Supply, But it May Be in Your Plumbing
Lead is usually a plumbing issue, not a water supply issue. While Aqua Pennsylvania treats water for lead, it can enter water if it passes through older plumbing materials. Homes built before the late 1980s are more likely to contain lead service lines, lead solder, or older brass plumbing components. Because every home’s plumbing is different, two neighboring houses can have very different lead levels, even though they’re served by the same water main.
The only way to know whether lead is present at your faucet is through a water quality test.
Why Does My Water Taste Like Chlorine?
If your tap water occasionally smells similar to a swimming pool, you’re right to wonder why.
Municipal water systems intentionally maintain a small amount of chlorine throughout the distribution network. This disinfectant helps prevent bacteria and other harmful microorganisms from growing as water travels through miles of underground pipes before reaching your home.
Although chlorine performs an important public health function, some homeowners simply don’t appreciate its taste or odor. It might also play a part in dry skin or dry hair after showering.
Fortunately, these concerns are easily addressed with a whole-home filtration system or drinking water filter. These systems can significantly improve taste and odor of your drinking water.

Hard Water Creates Problems That Go Beyond Drinking Water
Not every water quality issue is a health concern. Some of the most common homeowner complaints involve hard water, which contains elevated levels of naturally occurring calcium and magnesium. These minerals are not considered harmful to drink, but they can create frustrating problems throughout your home.
Hard water often causes:
- White spots on dishes and glassware
- Scale buildup on faucets
- Soap scum in showers
- Dry skin and dull hair
- Stiff laundry
Over time, mineral buildup inside your water heater, dishwasher, and plumbing fixtures can also reduce efficiency and increase maintenance costs.
If you’re experiencing these issues, a water softener can dramatically reduce mineral buildup throughout the plumbing system. Rather than filtering contaminants, water softeners remove hard minerals before they circulate through your home’s pipes, protecting both plumbing and water-using appliances.
There’s No One-Size-Fits-All Water Treatment System
One of the biggest misconceptions homeowners have is that installing “a water filter” solves every water quality concern. In reality, different technologies solve different problems:
- A water softener treats hard water minerals
- A sediment filter removes dirt, rust, and debris
- Activated carbon filtration improves taste and reduces chlorine
- Seagull IV filters provide highly purified drinking water
In many homes, the ideal solution isn’t a single system, it’s a carefully selected combination based on professional water testing.
That’s why Mattioni begins every service visit with understanding your home’s unique water quality before recommending equipment. Most homes on public city water are paired with a City Water Conditioning Package, and most homes on private wells are paired with a Well Water Conditioning Package.
Should West Chester Homeowners Be Concerned?
Overall, West Chester’s public drinking water continues to perform well under state and federal regulations. That’s encouraging news for homeowners.
At the same time, emerging contaminants like PFAS, demonstrate that “safe” water isn’t always the same as water that’s completely healthy and preferable to your home.
Understanding your own home’s water (not just the community’s annual water report) is the best way to make informed decisions.
