For many years, Pittsburgh has faced scrutiny over its tap water — especially due to issues with lead contamination and ageing infrastructure. But has the situation improved? Is the water safe to drink now?
This guide explores the current state of Pittsburgh water quality in 2026, including contaminants, treatment, testing options, and whether you should consider filtering your water at home.
Can you drink tap water in Pittsburgh today?
Yes — tap water in Pittsburgh is currently considered safe to drink and meets federal and state standards. The Pittsburgh Water and Sewer Authority (PWSA) reports high compliance with the Environmental Protection Agency (EPA) regulations.
However, historical issues — particularly with lead — mean many residents remain cautious. Filtering your tap water is still recommended, especially in older homes where pipes may leach contaminants.
Where does Pittsburgh’s water come from and who regulates it?
Pittsburgh’s drinking water primarily comes from the Allegheny River, which is treated at the Aspinwall Water Treatment Plant.
Water quality is regulated by:
- The EPA
- The Pennsylvania Department of Environmental Protection (DEP)
- Local oversight from the PWSA
These bodies ensure that over 90 contaminants are monitored regularly, including lead, chlorine byproducts, and microbial agents.
Common contaminants in Pittsburgh tap water
While the water is treated and tested, some trace contaminants may still be present:
- Lead: From ageing pipes and service lines in older homes
- Chlorine and chloramine: Used for disinfection; may affect taste or smell
- Haloacetic acids (HAAs) and trihalomethanes (THMs): Disinfection byproducts
- Nitrates and microbial contaminants: Monitored closely, especially after heavy rain or flooding
- PFAS chemicals: Detected at low levels in some areas
Many of these are within legal limits, but cumulative exposure over time is a valid concern — especially for children and pregnant women.
Lead concerns and infrastructure upgrades in Pittsburgh
One of the biggest water quality issues in Pittsburgh over the past decade has been lead contamination from old service lines. Although the lead is not in the water source itself, it can leach into the water from pipes built before 1986.
Recent updates:
- PWSA has replaced thousands of lead service lines since 2017
- A corrosion control treatment system was upgraded in 2019
- Ongoing public lead testing and transparency programmes remain active
Still, homes with old plumbing may benefit from additional filtration until all lead lines are removed city-wide.
Pittsburgh water quality reports: Highlights and recent data
The 2025 Consumer Confidence Report (CCR) from the PWSA shows:
- No violations of federal health-based standards
- Continued monitoring for lead and copper
- Low levels of chlorine, within safety limits
- Disinfection byproducts (THMs and HAAs) well under maximum levels
- PFAS levels detected but below state thresholds
Residents are encouraged to read their local report each year for specific data by neighbourhood or zone.
Water hardness in Pittsburgh: Is it soft or hard?
Pittsburgh’s tap water is classified as moderately hard, averaging 120–150 ppm (parts per million) of minerals like calcium and magnesium.
Hard water isn’t a health risk, but it can:
- Leave mineral deposits on taps and dishes
- Require more soap for washing
- Cause dry skin or hair for some people
Installing a water softener is optional — but not necessary for most homes. However, combining a general filter with a softener can improve both taste and skin feel.
How to test your water in Pittsburgh at home
Testing your water gives peace of mind — especially if you live in an older building. Here are your options:
- Free lead test kits from PWSA for qualifying households
- At-home water test kits for lead, chlorine, hardness, and bacteria
- Professional lab testing for comprehensive reports
- Smart water monitors that track real-time quality metrics
It's especially recommended to test if:
- You have a child under six
- You live in a pre-1986 home
- Your water tastes or smells unusual
Should you use a filter in Pittsburgh? Best systems and advice
Given the city's history with lead and disinfectants, many Pittsburgh residents choose to filter their water. Even if the water is technically “safe,” filtration improves both health and taste.
Top filter choices for Pittsburgh include:
- Faucet filters: Ideal for removing lead, chlorine, and microplastics
- Jug filters: Convenient and cost-effective
- Filtered bottles: Great for on-the-go hydration
- Shower filters: Help reduce skin irritation from chlorine
Solutions like Tappwater’s EcoPro or PitcherPro offer certified filtration for lead, chlorine, and disinfection byproducts, while maintaining essential minerals. They’re easy to install and eco-conscious, making them perfect for modern households.
